LoRaNow v1

LoRaNow Boards v1 is a PCB to help wiring between Atmega328p and RFM95 LoRa module to work with 2 AA batteries.

Detailed Description

This board has:

• Footprint for Atmega328p
• Footprint for RFM95
• Footprint for P-Channel Mosfet to turn on/off the RFM95
• Classic I2C connector (VCC, GND, SCL, SDA)
• Footprint for Diodes (DIO0/DIO1/DIO2 to pin 2)
• Footprint for Ultra Low Power controller TPL5110 (Optional)

Look at the schematics for more informations.
