## What it is
HID Remapper is an open-source programmable USB dongle, built on RP2040-based boards like the Raspberry Pi Pico, that remaps inputs from mice, keyboards, and other USB HID devices entirely in hardware. It is configured through a WebHID-based web tool and supports button/axis remapping, layers, macros, sensitivity changes, and polling rate overclocking.

## Use cases
- remap mouse buttons to keyboard keys
- change keyboard layouts with a hardware dongle
- adjust mouse sensitivity on the fly
- make a joystick act as a mouse
- make a keyboard work as a game controller
- overclock mouse polling rate to 1000 Hz
- set up drag-lock and scroll-by-moving-mouse behaviors
- build an accessibility input adapter for gaming

## When to choose
- you need input remapping that works in hardware with no host software
- you want per-device mappings for multiple USB input devices
- you need an accessibility-focused input translation device
- you want to remap inputs at the OS-independent firmware level

## When to avoid
- you only need software-level remapping on one OS
- you don't want to buy or assemble microcontroller hardware
- you need remapping of non-USB or non-HID devices
- you require a plug-and-play solution without flashing firmware
