Your Laptop Keyboard, On Another Device

A DIY project uses two RP2040 boards to turn a laptop's built-in keyboard into a USB HID keyboard for a headless machine like a Raspberry Pi. One RP2040 acts as a USB-to-serial bridge on the laptop side, and a second RP2040 receives that serial data and emits USB HID keystrokes, letting you type on the target device without a spare keyboard. Once initial setup is done, you can switch to SSH or another remote access method. Source code is provided for anyone with two RP2040 boards to replicate it.
