A simple PCB to control an Actiforce desk lift from a Blue Pill STM32 microcontroller board using two low-current relays.
The PCB itself is designed mostly one-sided, you just need a single jumper wire if you want a one-sided board. This makes it suitable for self-etching.
You can order the PCB on Aisler.
