Adafruit AirLift Bitsy Add-On – ESP32 WiFi Co-Processor [Discontinued] _ARD 8 GPIO pins (we have

8 GPIO pins (we have example code for this in our Arduino library)

Connect to it with any microcontroller over SPI and read out the resistance ratio from the internal ADC

Adafruit recommends the FONA 3G instead

wall adapter

need to use ALSA Softvol or volume control in the application

Adafruit AirLift Bitsy Add-On – ESP32 WiFi Co-Processor [Discontinued] _ARD 8 GPIO pins (we haveGive your ItsyBitsy project a lift with the Adafruit AirLift Bitsy Add On a daughterboard that lets you use the powerful ESP32 as a WiFi co processor. You probably have your favorite ItsyBitsy (like the Itsy' M4) that comes with its own set of awesome peripherals and lots of libraries. But it doesn't have WiFi built in! So lets give that chip a best friend, the ESP32. This chip can handle all the heavy lifting of connecting to a WiFi network and
