- 3x reference resistor 0k4 0.1% accuracy (Vishay PTF65400R00AZBF)
- 3x MAX31865 temperature reader SSOP package, Maxim Integrated
- 3x Adafruit PCB breakout TSSOP
- 9x 100nF and 3x 10nF capacitors
- micro SD card
- LiPoly battery
- optional: USB adapter
- breadboard sized headers, pins, switches, jumpers and screw terminals
