Adafruit sells Airlift hardware in multiple form factors in order to be compatible with many microcontroller boards. While each microcontroller board and airlift hardware combination has its own wiring scheme, we suggest either using the wiring below or referencing the AirLift product guide.
To use the AirLift FeatherWing with BLE, you will need to solder the three jumpers closed on the bottom of the AirLift FeatherWing:
After soldering the jumpers closed, we suggest using the FeatherWing Doubler to connect a Feather RP2040 and an AirLift FeatherWing side-by-side.
If you're using a Raspberry Pi Pico RP2040, make the following connections between the Pico RP2040 and an Adafruit AirLift breakout.
- Pico VSYS to AirLift Vin
- Pico GND to AirLift GND
- Pico GP13 (SPI1 CSn) to AirLift CS
- Pico GP14 to AirLift BUSY
- Pico GP16 to AirLift !RST
- Pico GP9 to AirLift GPIO0
- Pico GP0 to AirLift RXI
- Pico GP1 to AirLift TX0
