Despite the speed jump, it retains the UNO-shape form factor that ensures compatibility with the vast library of Arduino shields already on the market. WiFi connectivity is handled by an onboard ESP32 co-processor via SPI — the same AirLift approach used on other Adafruit Metro boards. The ESP32 manages TLS/SSL offloading so the main M7 core stays free for application logic. A drag-and-drop UF2 bootloader on the 8 MB QSPI Flash makes firmware updates as simple as copying a file. A STEMMA QT connector exposes an I2C bus so you can attach Adafruit's large ecosystem of sensors and displays without soldering. A 6–12 V barrel jack or USB-C can provide power, and an onboard On/Off switch adds convenience for battery-backed projects. SWD pads are available for advanced debugging. Note that CircuitPython support is the primary focus; the board is not compatible with the Arduino IDE or PlatformIO at this time. Adafruit distributes the board through DigiKey, Mouser, and Micro Center in addition to their own shop. ## Where to Buy - [Adafruit](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F4950&ref=openhardware.directory&product=adafruit-metro-m7-airlift&source=md-export) — 29.95 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F4950&ref=openhardware.directory&product=adafruit-metro-m7-airlift&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fadafruit%2FAdafruit-Metro-M7-PCB&ref=openhardware.directory&product=adafruit-metro-m7-airlift&source=md-export) - [learn guide](https://openhardware.directory/r?to=https%3A%2F%2Flearn.adafruit.com%2Fadafruit-metro-m7-1011-with-airlift&ref=openhardware.directory&product=adafruit-metro-m7-airlift&source=md-export) ## Tags `metro`, `imxrt1011`, `airlift`, `esp32-wifi`, `circuitpython`, `arduino-shield`, `usb-c`, `stemma-qt` ## Images ![Adafruit Metro M7 with AirLift](https://nbg1.your-objectstorage.com/openhardware-directory/entities/adafruit-metro-m7-airlift/c4fcd5d8518c.jpg) ![Adafruit Metro M7 with AirLift](https://nbg1.your-objectstorage.com/openhardware-directory/entities/adafruit-metro-m7-airlift/9eee55af522f.jpg) ![Adafruit Metro M7 with AirLift](https://nbg1.your-objectstorage.com/openhardware-directory/entities/adafruit-metro-m7-airlift/d749ad8e6a40.jpg) --- [View full device page](https://openhardware.directory/devices/adafruit-metro-m7-airlift)
