Get ready for our fastest Metro ever - the 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, plus a WiFi co-processor using an on-board ESP32 module.

The iMX series of chips is the fastest microcontrollers 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.
