Overview
1bitsy is an open-source printed circuit board by 1Bitsy, from the 1Bitsy/1bitsy-hardware repository on GitHub. It is a 4-layer board of 38.1 × 17.8 mm with 84 parts on 62 nets, routed with 695 tracks and 78 vias.
It is built around the STM32F415RGT6. Its parts include 43 connectors, 18 capacitors, 5 resistors, 3 crystals and 2 ICs. It belongs with the interfaces and adapters and sensors and measurement boards and the STM32 boards of this library.
Main components
1README
README.md1BitSy
This project includes 1BitSy evaluation boards. These boards are breadboard friendly STM32 (eventually other MCUs will be considered) with exposed Cortex JTAG and SWD interfaces. This allows the use of the Black Magic Probe, instead of the usually very limited built in debugger hardware.
Currently we have the following eval boards:
- 1BitSy V1.0d -> STM32F4x5RGT6
You can find the datasheet of the STM32F415RGT6 chip on the STMicroelectronics website.

Questions
How big is the 1bitsy PCB?
It measures 38.1 × 17.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the 1bitsy use?
84 parts, built around the STM32F415RGT6. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the 1bitsy KiCad files?
From the 1Bitsy/1bitsy-hardware repository on GitHub, at the commit this page was made from: the board is 1bitsy/v1.0a/1bitsy.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1bitsy design in my own project?
Its repository states no licence, so its author keeps all rights: ask 1Bitsy before reusing the design.
