Give your next project a lift with AirLift - Adafruit’s witty name for the ESP32 co-processor that graces this Metro M4.
You already know about the Adafruit Metro M4 featuring the Microchip ATSAMD51, with it’s 120MHz Cortex M4 with floating point support. With a train-load of FLASH and RAM, your code will be fast and roomy. And what better way to improve it than to add wireless? Now cooked in directly on board, you get a certified WiFi module that can handle all your TLS and socket needs, it even has root certificates pre-loaded.
This Metro is the same size as the others, and is compatible with all our shields. It’s got analog pins where you expect, and SPI/UART/I2C hardware support in the same spot as the Metro 328 and M0. But! It’s powered with an ATSAMD51J19:
Pretty good start, right? Adafruit put this chip on a PCB with all these nice extras:
The primary target for this board is CircuitPython - with 120 MHz, and 192KB of RAM CircuitPython runs really well on this chip! CircuitPython’s built in support for JSON parsing plus our requests compatible library makes it incredibly easy to build secure IoT projects in just a few minutes.
Metro M4 AirLift, see how easy and fast it is to get started with IoT projects using CircuitPython!

This is the latest stable release of CircuitPython that will work with the Metro M4 AirLift Lite.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the Metro M4 AirLift Lite.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
