# desklift

A simple PCB to control an Actiforce desk lift from a Blue Pill STM32

microcontroller board using two low-current relays.

![Picture 1: Front](pic1.jpg)

![Picture 2: Back](pic2.jpg)

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](https://aisler.net/p/MNKNKKFU).

This is a [LibrePCB](http://librepcb.org) project!
