Connect FONA to your Raspberry Pi or BeagleBone Black by following the appropriate steps below.
Raspberry Pi
Wire FONA to the Raspberry Pi as follows. If you aren't familiar with the pinout of the Raspberry Pi, see this page for an image of the header pins and their functionality.- FONA GND to Raspberry Pi ground.
- FONA Vio to Raspberry Pi 3.3 volt power.
- FONA GND to FONA Key.
- Note that this wiring will force FONA to stay active all the time the Raspberry Pi has power.
- FONA TX to Raspberry Pi RXD.
- FONA RX to Raspberry Pi TXD.
BeagleBone Black
Wire FONA to the BeagleBone Black as follows. If you aren't familiar with the pinout of the BeagleBone Black, see the Headers section of this page for images of the pins.- FONA GND to BeagleBone Black ground.
- FONA Vio to BeagleBone Black 3.3 volt power VDD_3V3 pin.
- FONA GND to FONA Key.
- Note that this wiring will force FONA to stay active all the time the BeagleBone Black has power.
- FONA TX to BeagleBone Black UART4 RX pin P9_13.
- If you aren't familiar with pin numbers on the BeagleBone Black, read the GPIO guide.
- FONA RX to BeagleBone Black UART4 TX pin P9_11.
