To220 powerstage: common questions

What microcontroller does the To220 powerstage use?

The To220 powerstage is built around the STM32F105RC, from the STM32 family.

How big is the To220 powerstage PCB?

The To220 powerstage measures 99.8 × 74.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the To220 powerstage?

125 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the To220 powerstage design files?

From the emdotnet/stmbl repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the To220 powerstage design in my own project?

Yes, under the terms of its GPL-3.0 license, which emdotnet chose for the repository.

Can I test firmware for the To220 powerstage 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.
