Your favourite electronics companies have collaborated to make the fastest Metro ever! For this new product, DigiKey, NXP and Adafruit all contributed the stuff they know best: shipping parts fast (DigiKey), designing microcontrollers (NXP) and crafting great products with tutorials (that’s us, Adafruit!)
We teamed up to present to you the Adafruit Metro M7 with
microSD
! An NXP iMX RT1011 microcontroller powers this board with a 500 MHz ARM Cortex M7 processor. There’s 8 MB of execute-in-place QSPI for firmware + disk storage and 128KB of SRAM in-chip. Arduino-compatible headers make using any ‘shield’ daughterboard easy. And, as you can expect, there’s a
micro SD card
slot wired up right on board so that you can read files or data logs easily to removable, wear-leveled storage.
The iMX series of chips is the fastest microcontroller around, with a Cortex M7 processor that is more powerful than the M0 or M4, and clock speeds of 500MHz+. For pure performance, there’s nothing better! This chip family is well known for being featured in the Teensy 4 dev board series. Now we have a Metro-shaped board so you can use many
Arduino shields
, that is fully open source so you can adapt the design to create your own custom layouts, and a USB drag-n-drop bootloader plus CircuitPython support for easy development. Beginners and experts alike will enjoy the combination of low cost, roomy memory and storage, and no-soldering quick start.
Please note that this board does not have Arduino or Platform.io support. You can program it with CircuitPython, a fast-to-start embedded version of the popular Python programming language, or with
MCU Xpresso IDE for C/C++ advanced embedded development
