Pride Badge prototype: common questions

What microcontroller does the Pride Badge prototype use?

The Pride Badge prototype is built around the STM32F042F6P6, from the STM32 family.

How big is the Pride Badge prototype PCB?

The Pride Badge prototype measures 100 × 130 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pride Badge prototype?

92 components, from 75 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pride Badge prototype design files?

From the aziraphale/pride-badge-v1 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Pride Badge prototype design in my own project?

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

Can I test firmware for the Pride Badge prototype 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.
