Arduino AirLift Shield ESP32 WiFi co-processor arrives at Adafruit

A new piece of Arduino hardware is now available to purchase from the Adafruit online store in the form of the Adafruit AirLift Shield. A piece of kit that offers you anΒ ArduinoΒ shield that allows you to use the ESP32 as a WiFi co-processor. If your favourite Arduino board doesn’t have integrated wireless connectivity the new AirLift Shield can rectify that. Handling all the heavy lifting of connecting to a WiFi network and transferring data from a site, even if it’s using the latest TLS/SSL encryption.

Adafruit explained a little more about the new piece of hardware and its features. β€œHaving WiFi managed by a separate chip means your code is simpler, you don’t have to cache socket data, or compile in & debug an SSL library. Send basic but powerful socket-based commands over 8MHz SPI for high speed data transfer. You can use any 3V or 5V Arduino, any chip from the ATmega328 or up (although the β€˜328 will not be able to do very complex tasks or buffer a lot of data). It also works great with CircuitPython, a SAMD51/Cortex M4 minimum required since we need a bunch of RAM. All you need is the SPI bus and 2 control pins plus a power supply that can provide up to 250mA during WiFi usage.”

The Adafruit AirLift Shield is now available to purchase priced at $15.95 and come supplied fully assembled and tested, pre-programmed with ESP32 SPI WiFi co-processor firmware that you can use in CircuitPython to use this into WiFi co-processor.
