Documentation and source files for my functional PCB business card

Hiya! Welcome to the documentation for my... business card? Yep, my business card. Which is also a PCB. Chances are you received one from me and are curious enough to scan the QR code on the back.

In these docs, you'll find information on the specs, how to flash it, which peripherals are onboard, how to do cool stuff with it, and (if you received a bare board) where to source the parts you'll need to assemble it. You'll also find the source KiCad project files for the schematic and board, as well as the source for the firmware that is installed by default. These are open source under…

Bizcard bkup: common questions

What microcontroller does the Bizcard bkup use?

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

How big is the Bizcard bkup PCB?

The Bizcard bkup measures 88.9 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bizcard bkup?

23 components, from 11 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bizcard bkup design files?

From the tjhorner/bizcard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Bizcard bkup design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which tjhorner chose for the repository.

Can I test firmware for the Bizcard bkup 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.
