Prism mainboard: common questions

What microcontroller does the Prism mainboard use?

The Prism mainboard is built around the STM32G031F6PX, from the STM32 family.

How big is the Prism mainboard PCB?

The Prism mainboard measures 100 × 100 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Prism mainboard?

82 components, from 37 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 Prism mainboard design files?

From the AveragePillow17/P.R.I.S.M. 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 Prism mainboard design in my own project?

The repository has no license, so all rights stay with AveragePillow17. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Prism mainboard 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.
