Pcb-Badge: common questions

What microcontroller does the Pcb-Badge use?

The Pcb-Badge is built around the RP2040, from the RP2040/RP2350 family.

How big is the Pcb-Badge?

The Pcb-Badge measures 73 × 41 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Pcb-Badge?

63 components, from 29 distinct parts. The full bill of materials is listed on this page.

Where can I download the Pcb-Badge design files?

From the souptik-samanta/Pcb-Badge repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Pcb-Badge design in my own project?

Yes, under the terms of its MIT license, which souptik-samanta chose for the repository.

Can I test firmware for the Pcb-Badge 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.
