Simple relay board to control automotive wiper motor from digital outputs
This board was created when I needed a way to control a MK2 VW wiper motor using outputs from my PDM.
Many PDMs require either external relays to drive wiper motors or use specific outputs designed to handle the wiper motor braking functionality.
Rather than include this specific feature on the PDM, I opted to create a simple relay board that can be placed inbetween the PDM and the wiper motor.
This setup also allows me to use 1 high current output to drive the motor at low speed or high speed, and one low current output to control that speed.
Wires are connected to the board using Deutsch DT 4 pin connectors

Questions
How big is the WiperModule PCB?
It measures 65.3 × 39.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WiperModule use?
8 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the WiperModule KiCad files?
From the corygrant/WiperModule repository on GitHub, at the commit this page was made from: the board is WiperModule/WiperModule.kicad_pcb and its schematic WiperModule/WiperModule.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WiperModule design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
