Moco-OD501: common questions
What microcontroller does the Moco-OD501 use?
The Moco-OD501 is built around the STM32G431CBT6, from the STM32 family.
How big is the Moco-OD501 PCB?
The Moco-OD501 measures 60 × 60 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Moco-OD501?
92 components, from 72 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-OD501 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-OD501 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-OD501 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.
