Arduino NANO & RFM69HCW

This board is designed to connect RFM69HCW to Arduino Nano.

Features:

  • Easy connect Arduino Nano
  • Power supply 3.3V for RFM module and Arduino Nano
  • BME280 on board (I2C address: 0x77)
  • DS18B20 on board

For proper operation of RFM module It's necessary to bypass internal 'power supply' (+5V) of Arduino Nano::

  • desolder schotky diode (with label 'S4') under the USB connector (step 1)

  • solder Pin between our board (+5V) and Arduino Nano (step 2)

Note: RFM69HCW (right side) is smaller than standard module RFM69HW (left side). Pin layout is also different. Dimensions of RFM69HCW are 16mm x 16mm enter image description here
