Circuit Diagram

This provides a visual reference for wiring of the components. This diagram was created using Fritzing software.

• RFM95W VIN to 3V on the Feather
• RFM95W GND to GND on the Feather
• RFM95W SCK to SCK on the Feather
• RFM95W MOSI to MOSI on the Feather
• RFM95W MISO to MISO on the Feather
• RFM95W CS to 11 on the Feather
• RFM95W RST to 12 on the Feather
• RFM95W G0 to A5 on the Feather

Button goes between Feather A0 and GND — internal pull-up, so no external resistor needed. Sensor on the STEMMA QT port with a JST SH cable, so no soldering.

SCK, MOSI and MISO are shared with the eInk Feather Friend, so D5, D6, D9 and D10 are unavailable.
