this is version 2 (or technically version 3) of a project that all started because I was too lazy to buy a level shifter.

this project uses a Raspberry Pi Pico RP2040 microcontroller (seen above). past hardware revisions include an off-brand Arduino Uno R3 (no picure) and a Genuino Arduino Leonardo ([picure](https://ben.wiegand.pw/img/smbus-mitm-arduino-thumb.webp)).

the Arduino version had major technical limitations that made me not want to release it. also I blew up the arduino.
