BoSL Board v0.3

BOSL BOARD - THE ULTRA LOW POWERED IOT LOGGING DEVICE

This little beauty costs less than an Arduino and Sim5320a put together, yet it comes already assembled, runs on 4v, is ultra low power consuming (we removed all the overheads of the off the shelf arduinos) and can send data via the CAT-M1 or NB-IoT networks! We estimate that these things can log each minute for over 12months!
