Already have a compatible remote? An ESP32-C3 board costs about $5 and a remote about $10; a full set runs about $15.
Prices are project estimates. Check compatibility before you buy.

Xiaomi remotes use a preset; other remotes are learned key by key.

03 / BUILT TO BE SIMPLE
Install less, use more.
The bridging happens on the board; your PC just sees a standard Bluetooth keyboard. Open the web page only when you want to change something.
Cheap to build
About $5 for the board, plus a compatible Bluetooth remote at around $10 — ideally one you already own.
Windows drivers untouched
It connects as a standard Bluetooth HID device and never modifies, replaces or injects a keyboard driver, which keeps it clear of anti-cheat, antivirus and system-stability trouble.
Configured in the browser
Connecting, Wi-Fi setup and key mapping each have their own entry. A device that already runs the firmware never needs reflashing just to change Wi-Fi.
Every RC003 key works
All 13 keys are supported, including the special ones Windows usually cannot read; the board converts them to standard HID before sending them on.
Keys forwarded locally
The key path from remote to PC runs over Bluetooth; the config page’s Wi-Fi only opens inside its own time window.
Open source, keep hacking
The firmware ships under GPL-3.0-or-later, with readable source and config so you can keep improving it.
04 / COMPATIBILITY

Bluetooth HID support on your PC and the browser requirement for the USB connection are two different things; the section below checks this browser for Web Serial.
05 / GET CONNECTED
Plug in USB, then click “Connect device”.
A blank board gets the installer; a device that already runs the firmware can update, join Wi-Fi, show logs or open its config page.
1Pick a serial port
2Install / Wi-Fi
3Open the config page
ESP Web Tools · official flow
Plug the board in and connect once.
Once you pick the port, the official component recognizes the device: a blank board is offered MiRemoteBridge; an existing device gets update, Wi-Fi, logs and its config page.
Loading the official component…
Firmware install optionsRarely needed
Erase installs and factory resets are still confirmed in the official ESP Web Tools dialog.
Checking Web Serial and the official component…
Wi-Fi already closed, or unsure which install to pick?
If the official dialog says Wi-Fi is closed, tap BOOT on the board and try again. Keep “Full firmware” for everyday use; “App only” is for devices that already run MiRemoteBridge with an unchanged partition table.
