Give 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 transferring data from a site, even if its using the latest TLS/SSL encryption (it has root certificates pre-burned in). https://elecena.pl/product/17502451/adafruit-airlift-bitsy-add-on-esp32-wifi-co-processor 2021-04-07 https://elecena.pl/product/17502451/adafruit-airlift-bitsy-add-on-esp32-wifi-co-processor 2024-01-16 https://elecena.pl/product/17502451/adafruit-airlift-bitsy-add-on-esp32-wifi-co-processor 2024-01-17 https://elecena.pl/product/17502451/adafruit-airlift-bitsy-add-on-esp32-wifi-co-processor 2026-03-17
