Opq: common questions

What microcontroller does the Opq use?

The Opq is built around the STM32F373CCT6, from the STM32 family.

How big is the Opq PCB?

The Opq measures 85.2 × 93.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Opq?

51 components, from 28 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 Opq design files?

From the openpowerquality/opq repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Opq design in my own project?

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

Can I test firmware for the Opq 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.
