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.
