Game and watch hardware: common questions

What microcontroller does the Game and watch hardware use?

The Game and watch hardware is built around the STM32H7B0VGT6, from the STM32 family.

How big is the Game and watch hardware PCB?

The Game and watch hardware measures 108.7 × 55.1 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Game and watch hardware?

155 components, from 55 distinct parts. The full bill of materials is listed on this page.

Where can I download the Game and watch hardware design files?

From the Upcycle-Electronics/game-and-watch-hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Game and watch hardware design in my own project?

Yes, under the terms of its MIT license, which Upcycle-Electronics chose for the repository.

Can I test firmware for the Game and watch hardware without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
