Final version of my control PCB for turnout motor, indicator leds, and pushbuttons. You need one of these boards per turnout. Production process was fast and smooth. Shipping was also flawless. Thanks a lot, PCBWay !!!

It's a heart-shaped PCB based on https://github.com/fellettigiacomo/NeoHeart but I reduced the number of LEDs and added a MAX30102 sensor to read the users's heartbeat and pulse the onboard LEDs accordingly. Sierra was in charge of overseeing the assembly and they did a pretty good job, I am very happy, everything is working correctly and they took every measure they could to ensure that because they reached out to me multiple times for confirmation.
