Pinout

Low source legibility.The original manufacturer datasheet for this part was difficult to read, so this pinout may be incomplete or imperfect. Always confirm against the specific manufacturer’s datasheet before wiring.

Pin	Name	Functions	Notes
GND	GND	GND	Common power/logic ground.
BAT	BAT	—	Positive voltage from JST on Feather for an optional LiPo battery.
USB	USB	POWER	Positive voltage to/from the Micro USB jack if connected.
EN	EN	—	3.3V regulator's enable pin. It's pulled up, so connect to ground to disable the 3.3V regulator
3V	3V	POWER	Output from the 3.3V regulator.
SCK	SCK	SPI	SPI Clock from your microcontroller, level shifted so can be 3-5V logic
MISO	MISO	SPI	SPI Data from the AirLift to the microcontroller, this is 3.3V logic out, can be read by 3-5V logic.
MOSI	MOSI	SPI	SPI Data to the AirLift from the microcontroller, level shifted so can be 3-5V logic
ESPCS	ESPCS	SPI	SPI Chip Select from the microcontroller to start sending commands to the AirLift, level shifted so can be 3-5V logic
ESPBUSY	ESPBUSY	—	This pin is an input from the AirLift, it will let us know when its ready for more commands to be sent. This is 3.3V logic out, can be read by 3-5V logic.
ESPRST	ESPRST	—	This pin is an output to the AirLift. Set low to put the AirLift into reset. You should use this pin, even though you might be able to run for a short while without it, it's essential to 'kick' the chip if it ever gets into a locked up state.
ESPGPIO0	ESPGPIO0	GPIO	This is the ESP32 GPIO0 pin, which is used to put it into bootloading mode. It's also used if you like when the ESP32 is acting as a server, to let you know data is ready for reading.
ESPRX	ESPRX	UART	Serial data in, used for bootloading new firmware. Leave disconnected if not using BLE or when not uploading new WiFi firmware to the AirLift (which is a rare occurrence).
ESPTX	ESPTX	UART	Serial data out, used for communication when in BLE mode. Leave disconnected if not using BLE or when not uploading new WiFi firmware to the AirLift (which is a rare occurrence).
