An Arduino shield accepting a Nano, eeprom and a BMP280 barometric pressure sensor. When a datalogger shield and a RGB LCD shield are added this will display and log the temperatures and ABV values during a distillation run. Fabrication is ultra fast and the delivery of a second slightly revised version was delivered to an address in China in two days and 4 hours (not kidding) after ordering them. The design is done in KiCad and for the second order the round holes were changed for the oval holes as standard in the footprint of the barrel jack in Kicad. PCBway had no problem with this. I think this is something they should advertise with. The quality of the boards is outstanding. What more to say? Highly recommended!
