Don’t let the smaller size fool you; the 4.0 is based on an ARM Cortex M7 running at 600 MHz (!), the fastest microcontroller you can get in 2019, and testing on real-world examples shows it ...

The hardware consists of not much more than an ARM Cortex-M7 MCU, a 240×320 LCD screen and a few buttons soldered onto a piece of prototyping board, all powered by a set of AAA batteries.

The Cortex-M7 processor enables partners to build the most sophisticated variety of MCUs and embedded SoCs. It has been designed to deliver a very high level of performance, while maintaining the ...
