Crowd Supply D-MARK Controller Board

Crowd Supply D-MARK Controller Board with a microSD is a versatile, open-source development board designed to leverage the STM32F070RB ARM microcontroller’s price-to-performance ratio. The D-MARK Controller Board includes open-source D-MARK Script Interpreter (DMSI) firmware, eliminating the need for a programmer. The easy-to-use board needs a few lines of text to a microSD card, slot it in, and watch D-MARK go to work.

Unlike many development kits, D-MARK includes a curated set of inputs and outputs that were carefully chosen to facilitate real-life applications and prevent re-investing in hardware. D-MARK is a fast and economical way for users to begin exploring the world of ARM microcontrollers.
