Led interposer: common questions

What microcontroller does the Led interposer use?

The Led interposer is built around the STM32G474RETX, from the STM32 family.

How big is the Led interposer PCB?

The Led interposer measures 6.4 × 6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Led interposer?

3 components, from 3 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 Led interposer design files?

From the Mouse-GYM/auto-trainer-hardware 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 Led interposer design in my own project?

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

Can I test firmware for the Led interposer 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.
