Open-Source Miniature Breadboard Friendly ARM Cortex-M4F Dev Board with 1MB Flash, 196kB RAM, 168MHz, floating point and more.

What is it?

1Bitsy is a debuggable open source STM32F415 development board. Designed for beginners as well as advanced users that want more control over their embedded software by exposing the JTAG/SWD debug interface that is compatible with the Black Magic Probe JTAG/SWD debugger with built in GDB server.

What makes 1Bitsy special

The main goal of the 1Bitsy platform is openness. We want to provide a platform that is not artificially trying to hide complexity to provide a false sense of simplicity but rather expose the amazing power of an ARM Cortex-M4F core and the STM32F415 peripherals to take advantage of. Also the chip we have chosen has lots of space for your code and runs at 168MHz making it a fast and spacious work horse.
