Badges: common questions

What microcontroller does the Badges use?

The Badges is built around the RP2040, from the RP2040/RP2350 family.

How big is the Badges PCB?

The Badges measures 84 × 98 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Badges?

83 components, from 42 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 Badges design files?

From the sophiayduan/badges 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 Badges design in my own project?

Yes, under the terms of its Unlicense license, which sophiayduan chose for the repository.

Can I test firmware for the Badges without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
