2 layer board of 0.74 x 1.52 inches (18.7 x 38.6 mm)
Uploaded: July 2nd 2015
Shared: July 24th 2015
Total Price: $5.60

PCB will take 3.3V pro mini or 5V pro mini and connects to NRF24L01+ radio.


Version 2 Fixes

  • fixes some orphaned Ground Planes
  • Replaces the thru-hole resistors with SMD
  • adds power “ports” for various things like relay, PIR, and Temp sensors

For 3.3V Battery powered Sensor:

  • No place the AMS1117 regulator
  • Tie 3v3,IN,and VCC together.
  • Can also place Resistors R1 (1M) and R2 (470k), and C3 (0.01uF) to measure battery voltage on A0
  • Should also place C2 (10uF to 47uF or whatever works best in your environment) for more stability on Radio.

For 5V powered sensor (like from USB charger):

  • Place AMS1117 3.3V regulator.
  • Place C1 and C2
  • Tie VCC to VIN option.
  • Do NOT place R1, R2, or C3 (no battery sensor).

Other Notes

  • D8 – D3 have extra headers
  • A3 – A1 have extra headers
  • A7 – A4 have headers on pro mini itself.
  • See mySensors.org for more information. This PCB is not officially affiliated with MySensors.
