The Radio Bonnet for Raspberry Pi sets you up with a RFM9x (or RFM69HCW) Radio Module, a 128x32 OLED display and three push-buttons. 

If you have this bonnet, everything is already "wired up" for you - move on to setting up your Raspberry Pi.

Raspberry Pi Breadboard Wiring

Wiring the Push-Buttons

We'll start by wiring three buttons. These will the physical interface between the Raspberry Pi and the Radio - we'll want to control the radio by pressing some buttons.

Make the following connections between the Pi and the three push-buttons:

  • Pi GPIO #5 to Button A (orange wire)
  • Pi GPIO #6 to Button B (blue wire)
  • Pi GPIO #12 to Button C  (green wire)
  • Pi 3.3V to Power Rail (red wire)
  • Pi GND to Ground Rail (black wire)

Wiring the OLED

  • Display GND to Raspberry Pi GND (black wire)
  • Display Vin to Raspberry Pi 3.3V (red wire)
  • Display SCL to Raspberry Pi SCL (green wire)
  • Display SDA to Raspberry Pi SDA (yellow wire)

Wiring the RFM Radio Module

Make the following connections between the Raspberry Pi and the RFM Radio Module:

  • Vin to Raspberry Pi 3.3V
  • GND to Raspberry Pi Ground
  • RFM G0 to Raspberry Pi GPIO #5
  • RFM RST to Raspberry Pi GPIO #25
  • RFM CLK to Raspberry Pi SCK
  • RFM MISO to Raspberry Pi MISO
  • RFM MOSI to Raspberry Pi MOSI
  • RFM CS to Raspberry Pi CE1

Next, let's move on to installing the necessary files for this project.
