Moco rc1: common questions
What microcontroller does the Moco rc1 use?
The Moco rc1 is built around the STM32G431CBT6, from the STM32 family.
How big is the Moco rc1 PCB?
The Moco rc1 measures 35 × 35 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Moco rc1?
80 components, from 68 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Moco rc1 design files?
From the ziteh/moco repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Moco rc1 design in my own project?
Yes, under the terms of its CERN-OHL-P-2.0 license, which ziteh chose for the repository.
Can I test firmware for the Moco rc1 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.
