cactuar
a wireless keyboard receiver for the raspberry pi pico.
Cactuar is a program I created for the Raspberry Pi Pico, which transforms the Pico into a wireless keyboard reciever. I had created it so I could easily switch my keyboard between my computer and PS5. I had originally written a working version using C and FreeRTOS, but I was having performance issues (input lag and delays) so I switched to using Rust and Embassy which lead to much better performance.
features
- Forward keyboard input to the Pico from a Windows or Linux computer
- Works over Wi-Fi
- Encyption using ChaCha20-Poly1305
- Works with any device that supports USB keyboards
