Board for contact temperature measurement with the use of thermistors. The board is intended to be used in calibrating the IR thermometer board.
Originally, ItsyBitsy 32u4 was used, but due to that MCU's insufficient ADC resolution, ItsyBitsy nRF52840 Express is now used. The new board has the same form factor and a compatible pinout, so no modification to the PCB was necessary.
Arduino core used is Adafruit Bluefruit nRF52 v1.6.0.
InterboardSerial custom library is used for communicating with the IR thermometer board.

Thermistors monitor temperature with resistance. This article by Adafruit explains the bulk of theory used in creating the PCB as well as making calculations in the software.
