it's a begginner to medium level soldering kit. but not a beginner's kit.

it's made up of an ESP32 running micropython (obviously you're free to run rust on an emulated 6502 if that's your kink!) and a RTC module and one of our large 6 digit digitus16 RGB displays of 16-segment displays. HW and SW are fully opensource in case you wonder =)
