User Manual

two RX/TX LEDs for data being sent over USB, and a red LED connected. Next to the reset button there is an

RGB NeoPixel that can be used for any purpose.

2 MB QSPI Flash storage chip is included on board. You can use the SPI Flash storage like a very tiny hard drive.

When used in Circuit Python, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in

Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access

the files over USB.

Easy reprogramming, comes pre-loaded with the UF2 bootloader (https://adafru.it/wbC), which looks like a USB

storage key. Simply drag firmware on to program, no special tools or drivers needed! It can be used to load up

CircuitPython or Arduino IDE (it is bossa v1.8 compatible)

We have a working Arduino board support package, with lots of stuff working, but our 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.

So what are you waiting for? Pick up a Metro M4 AirLift today and be amazed at how easy and fast it is to get started

with IoT projects using CircuitPython!
