Moco pg4: common questions
What microcontroller does the Moco pg4 use?
The Moco pg4 is built around the STM32G431CBT6, from the STM32 family.
How big is the Moco pg4 PCB?
The Moco pg4 measures 40 × 40 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Moco pg4?
90 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 pg4 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 pg4 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 pg4 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.
