Pride Badge: common questions
What microcontroller does the Pride Badge use?
The Pride Badge is built around the STM32F042F6P6, from the STM32 family.
How big is the Pride Badge PCB?
The Pride Badge measures 65.2 × 72.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Pride Badge?
128 components, from 102 distinct parts. The full bill of materials is listed on this page.
Where can I download the Pride Badge 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 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 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.
