NEW GUIDE: MicroPython Hardware: SD Cards @micropython

 

MicroPython Hardware: SD Cards is a new guide in the learning system:

Secure Digital, or SD, cards and tiny microSD cards are inexpensive and ubiquituous means of adding lots of storage to devices.  For a few dollars you can have gigabytes of storage at your fingertips (smaller than your fingertips actually!).  With small MicroPython boards you typically have a very limited amount of flash memory to store code and data.  Wouldn’t it be nice if you could connect a microSD card to a MicroPython board and expand its storage?  It turns you can use microSD cards with MicroPython!  In fact some boards like the pyboard come with microSD card support built-in, and for other boards like the ESP8266 they can easily be connected to a microSD card that expands their storage.

This guide explores how to use a microSD card as the root filesystem for a MicroPython board.  Specifically adding a microSD card to the pyboard, WiPy, and ESP8266 will be covered in this guide.  You’ll learn how to connect a microSD card to the board and mount it as a new root filesystem that MicroPython can use to store code & data just like its internal filesystem.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
