1.2 - Specifications

This page lists every hardware specification, supported platform, and compatibility limitation of ReaSnow S2.

Port Layout

Hardware Specifications

Supported Platforms

PS5 Connection Options

Unsupported Features

S2 is a keyboard and mouse converter. The following features are not supported and are marked for clarity:

Peripheral Compatibility Summary

Recommended Mouse Settings

⚙️ Advanced: Each Game Config calibrates the Intelligent Mouse Engine for its target game. Set your in-game settings to what the config recommends.

1.3 - APP Usages & Settings

This page covers the Home, Configs, Settings and etc section of the ReaSnow Manager APP. For account management (login, registration, membership), see Account System.

APP Orientation

The main interface has 4 tabs at the bottom:

Settings Menu

Open Settings from the bottom tab bar to access:

Global Settings

Boot Mode

Sets which platform S2 emulates on boot. The correct mode must match your console and authentication method.

The selector shows all 8 modes as visual radio tiles. Tap a mode, confirm, and S2 automatically restarts into that mode.

USB Report Rate

Higher report rates reduce input latency. Changing the rate causes S2 to restart automatically.

Mute Mode

Controls how the mute hotkey behaves:

Office Mode

When enabled, S2 outputs as a standard keyboard and mouse rather than a controller — useful for desktop tasks.

Custom Bluetooth Name

Set a friendly name (up to 15 UTF-8 bytes) for S2’s BLE broadcast. Helps identify your device when multiple S2 units are nearby.

IO Monitor

The IO Monitor is a real-time input viewer — a unique S2 feature not found on competing converters.

💡 Tip: The IO Monitor is your best debugging tool. If a button isn’t working in-game, open this page and press it — you will immediately see whether S2 detects the input and what it maps to.

Hotkey Selector

Every action that can be bound to a key (config switching, macro activation, mute, office mode) uses the Hotkey Selector to assign the trigger.

⚙️ Advanced — Search: Instead of picking from a grid, you press the actual key you want to use, and S2 learns it instantly. This is the fastest way to set a hotkey, especially for unusual keyboards.

1.4 - Bluetooth Pairing

S2 communicates with the ReaSnow Manager APP exclusively over Bluetooth Low Energy (BLE). There is no USB data connection between the APP and S2 — all configuration, firmware updates, and real-time monitoring happen wirelessly.

First-Time Pairing

1. Power on S2 — the LED will show slow-flashing blue (waiting for BLE connection).
2. On your phone, turn on Bluetooth and Location/GPS.
3. Open the ReaSnow Manager APP.
4. The APP automatically scans for nearby S2 devices — look for a device name starting with ReaSnow-S2- followed by a unique identifier.
5. Tap your S2 in the device list to connect.
6. The LED changes to solid blue when connected.

ℹ️ Info: Grant Bluetooth and Location permissions when asked. On Android, BLE scanning requires Location permission at the OS level — this is an Android requirement, not an S2 requirement.

Auto-Reconnect

S2 remembers the last paired phone. After the initial pairing:

• Power on S2 → the APP auto-reconnects within 5 seconds (if the APP is open and Bluetooth is on).
• If the BLE connection drops unexpectedly, the APP automatically attempts to reconnect.
• Upon reconnect, the APP resets to the Home tab.

Connection Rules

Custom Bluetooth Name

Set a custom name for your S2’s BLE broadcast to make it easy to identify when multiple units are nearby:

1. Go to Settings → Global Settings → Custom Bluetooth Name.
2. Enter a name up to 15 bytes (UTF-8).
3. Tap Save — the new name takes effect immediately.

Useful in tournament or LAN party settings where several players may have S2 devices in range.

Troubleshooting

💡 Tip: If nothing else works, restart your phone’s Bluetooth, power-cycle S2, and try again. This resolves most BLE pairing issues.

1.5 - Firmware Update

S2 firmware is updated wirelessly through the ReaSnow Manager APP — no PC, no USB cable, no file downloads required.

Update Channels

Choose a channel based on your needs:

💡 Tip: Stay on the Stable channel unless you are testing a specific fix or feature with guidance from ReaSnow support.

How to Update

1. Open the ReaSnow Manager APP and connect to S2.
2. Navigate to Settings → Firmware Upgrade.
3. The APP checks the server for available updates.
4. If a newer version is available, tap Upgrade.
5. The upgrade proceeds in four phases:

During the Update

Important Notes

⚠️ Warning — follow these or the upgrade may fail:

Recovery

If an upgrade fails:

1. The APP shows an error message with the failed phase.
2. S2 remains in its current working state — a failed upgrade does not brick the device.
3. Tap Retry to attempt the upgrade again.
4. If repeated attempts fail, try:
   • Moving closer to S2 (within 1 meter).
   • Restarting the APP.
   • Power-cycling S2.
   • Switching to a different phone if BLE performance is consistently poor.

If the issue persists, contact ReaSnow support with your current firmware version and the error message.

2 - Tuning & Configuration

Customize every aspect of your S2 setup.

2.1 - Aim Tuning

This section covers everything related to mouse aim tuning on S2 — from basic sensitivity setup to the 50-point curve editor and dead zone configuration.

Before You Tune

Get these fundamentals right first:

Set your mouse to the recommended DPI and report rate using your mouse manufacturer’s software or onboard DPI button before connecting to S2.

Sensitivity Parameters

These are adjusted in the APP’s Mouse Advanced Settings page.

⚙️ Advanced: HIP and ADS each have independent sensitivity values. This lets you keep fast turning while hip-firing and a slower, more precise speed when scoped in.

Response Curve

S2 uses a 50-point Catmull-Rom spline curve that maps physical mouse movement to in-game stick output. Each point is a control node you can drag to reshape the response.

Learn how to use the curve editor in detail: Curve Editor

Dead Zone

If your aim drifts when you are not touching the mouse, or the crosshair moves too abruptly from a standstill, adjust the dead zone. This is also where you fine-tune the controller stick dead zone for authentication and gameplay.

Full reference: Deadzone Settings

Aim Assist

S2 offers two aim-assist algorithms for games that benefit from stick-acceleration-style reticle friction:

⚠️ Warning: Aim assist behavior varies by game. Test both options in your game’s practice range before committing to one.

Saving Your Settings

All aim parameters are automatically synced to S2’s RAM as you adjust them. To make settings permanent across power cycles, tap Save to Flash — otherwise changes are lost when S2 powers off.

2.1.1 - Curve Editor

The curve editor maps your physical mouse movement to in-game stick output. A well-tuned curve makes aiming feel natural — the crosshair moves exactly where you expect it to.

How It Works

S2 samples your mouse movement and translates it through a Catmull-Rom spline curve with up to 50 control points. The X axis represents physical mouse speed; the Y axis represents the stick output sent to the console. Each point is an anchor you can drag to reshape the response.

5 Preset Curves

Start from a preset, then fine-tune. Tap any preset to load it onto the canvas.

Editing Controls

Axis Options

For specialized scenarios, you can lock or swap the response axes:

💡 Tip: Most players leave both axes unlocked. Use axis locking only if you need different horizontal vs. vertical response — e.g., reducing vertical bounce during anti-recoil macros.

Per-Game Recommendations

Each official Game Config ships with a recommended curve tuned for that specific game. When you install a Game Config from the library, the curve is included automatically.

To see what curve the config recommends, open the curve editor after loading the config — the preset and point positions reflect the author’s tuning.

2.1.2 - Deadzone Settings

Dead zones define how much physical movement is ignored before S2 begins outputting a stick or trigger signal. Properly tuned dead zones eliminate drift, reduce unwanted movement, and make stick response feel consistent across different controllers.

Controller Stick Dead Zone

Two controllers can have their dead zones configured: the authentication controller (plugged into USB1) and the main controller (USB2–4).

Authentication vs. Main Controller

Trigger Dead Zone

Configure the inner and outer dead zone for analog triggers (L2/R2) on connected controllers.

Trigger dead zones are useful for games where you want a hair-trigger response (lower inner dead zone) or need to prevent accidental trigger activation (higher inner dead zone).

Numeric Input

Every dead zone slider supports precise numeric entry. Tap the value to open an input box and type the exact number you want — no need to guess with the slider.

Dead Zone Shape

For the main controller sticks, choose between two dead zone shapes in the Game Settings page (alongside keybinding configuration):

💡 Tip: Start with Circle and a low inner dead zone (5–10). Increase only if you notice stick drift on the IO Monitor.

Per-Game Differences

Different games interpret stick input differently. A dead zone that works for one FPS may cause sluggish aim in another. Always test after changing:

1. Open the IO Monitor to see real-time stick values.
2. Move the stick to the edges — verify both X and Y reach 100%.
3. Release the stick — verify both axes return to 0.
4. Adjust the inner dead zone up if values do not settle at 0, or adjust the outer dead zone down if values do not reach 100%.

⚠️ Warning: Setting the inner dead zone too high can create a “jump” when the stick passes the threshold. Keep the inner dead zone as low as your hardware allows.

2.2 - Macro System

S2’s macro system lets you record and play back sequences of button presses with millisecond precision. Use it for anti-recoil patterns, movement combos, rapid building, and any repeated input sequence.

Macro Structure

Think of a group as a “loadout” for one game or playstyle. Switch between groups to change your entire macro setup.

Group Settings

Each macro group has independent settings:

Trigger Modes

Execution Modes

Macro Editor

The visual timeline editor is the core of macro creation. Each row is a time step; each column is an action.

💡 Tip: Use the Play Test button to preview the macro in the editor before saving it to S2. The IO Monitor shows exactly what the macro outputs.

Anti-Recoil Macros

Anti-recoil macros are specialized macros that compensate for vertical weapon kick during ADS:

Create a short sequence of downward stick movements timed to your weapon’s fire rate. The macro editor’s ms-level precision lets you match the recoil pattern exactly.

Macro Element Selector

When adding actions to the timeline, choose from three input categories:

7 Scenario Examples

These real-world examples show what the macro system can do:

Recording a Macro

1. Open the macro editor for the target macro slot.
2. Tap the Record button.
3. Press keys and buttons on your connected devices — S2 captures timing and order.
4. Tap Stop to finish.
5. Use the timeline editor to adjust timing, add delays, or insert new actions.
6. Tap Play Test to preview.
7. Save to Flash to persist to S2.

⚠️ Warning: Macros are saved to RAM automatically as you edit. Tap Save to Flash before powering off S2, or your changes will be lost.

2.3 - Keybinding

Keybinding translates your keyboard and mouse inputs into controller outputs. Each mapping tells S2: “when this key is pressed, send that controller button to the console.”

Config Structure

Sub configs let you switch mapping layouts by context. For example, a sniper button that changes scope while ADS uses one mapping in the HIP config and a different one in the ADS config.

Sub Config Inheritance

Sub configs 2–5 can inherit mappings from the HIP config:

• ADS inherits from HIP
• TBD1 inherits from HIP
• TBD2 inherits from HIP
• TBD3 inherits from HIP

Inheritance means you use the same mappings.

Keybinding List

The mapping list shows all slots with their default keys and target outputs:

Mapping Methods

⚙️ Advanced — Search: Instead of picking from a grid, you press the actual key you want to use, and S2 learns it instantly. This is the fastest way to set a hotkey, especially for unusual keyboards.

Combo Keys

A combo combines two input keys (from keyboard, mouse, controller, or any compatible device) into a single virtual key, which is then mapped to a controller button output or used to activate a feature.

Each combo group holds 8 combo entries. Press the two assigned input keys simultaneously to trigger the virtual key, useful for actions that benefit from two-handed input or to create unique shortcuts that avoid normal-key conflicts.

💡 Tip: Combo Keys should be set properly in the “Combo Keys” page before its usage

Analog Behavior

AB converts a digital key press into a timed analog stick/trigger movement - the controller sees the stick/trigger move, not a button press.

💡 Tip: A game requires analog-style input for certain actions — AB converts a key press into that analog signal.

Vibration

Route vibration feedback to a connected controller:

Saving Keybindings

Keybindings auto-sync to S2’s RAM as you edit. Changes are temporary until you tap Save to Flash — do this before powering off, or your mapping setup will revert.

2.4 - Flight & Arcade Stick

S2 supports flight sticks (including standalone throttles), arcade sticks, and gyro-to-stick conversion. This page covers axis mapping, speed limits, and dead zone configuration for these peripherals.

⚠️ Warning: Steering wheels, pedals, force feedback, and any racing wheel subsystems are not supported on S2. See Specifications for the full unsupported features list.

Supported Peripherals

Stick Settings

These apply to both analog sticks detected by S2:

Gyro-to-Stick

S2 can translate gyroscope motion from a supported controller into analog stick output — enabling motion-based aiming in games that do not natively support gyro.

💡 Tip: Gyro-to-stick sensitivity is controlled through the stick speed settings above. Increase right stick max speed for faster gyro response.

Flight Stick Axis Mapping

Each analog axis on a flight stick can be mapped independently to any S2 input port:

A typical HOTAS maps:

• X axis → Roll (ailerons)
• Y axis → Pitch (elevator)
• Z axis → Rudder (twist or pedal)
• Slider → Throttle

Stick Response Curves

Multiple response curve types are available for analog sticks — choose based on your game and playstyle:

Select the curve in the stick settings page. The curve applies to the analog stick output, similar to how the mouse curve editor controls mouse-to-stick translation (see Curve Editor).
