## What it is
An Arduino/PlatformIO library that turns ESP32-family microcontrollers into Bluetooth LE HID gamepads. It supports up to 128 buttons, 6 axes, sliders, hats, gyro/accelerometer, and battery reporting via the efficient NimBLE stack.

## Use cases
- make an ESP32 act as a wireless game controller
- build a custom BLE gamepad with Arduino
- emulate a HID gamepad over Bluetooth LE
- create a DIY flight sim controller with throttle and rudder
- send gyroscope and accelerometer data as gamepad motion
- pair a microcontroller controller with Windows or Android

## When to choose
- you need a custom hardware controller for PC, Android, Linux, or macOS
- you want configurable HID descriptors, VID/PID, and axes resolution on ESP32
- you need battery reporting or force-pairing control in a BLE gamepad

## When to avoid
- you need iOS compatibility, which is not supported (no MFI)
- your board is an ESP32-S2, which has no Bluetooth radio
- you want classic Bluetooth (non-LE) HID emulation

## Facets
- artifact type: library
