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.
