About the PCB business card

PCB business card is an open source ESP32 PCB design by fab-pie, published on GitHub. It is a 4-layer board measuring 49 × 74.9 mm, with 301 components from 36 distinct parts.

Its main chip is the ESP32-H2-MINI-1, from the ESP32 family. Other key parts include the TPS631000DRLR, MCP73833, A3908 and AP2204. By type, the board carries 135 capacitors, 120 LEDs, 25 resistors, 5 ICs, 5 diodes and 4 switches.

It belongs with the iot & wireless designs in this gallery.

From the project

A custom PCB based "business" card that lets you play a version of Flappy Bird.

These are structured into their own files. I could have used submodules, but decided against it.

The script requires the config.py file to be modified. You will need to create your own API key at openweather.org

To run the script, simply run python CardController.py

PCB business card: common questions

What microcontroller does the PCB business card use?

The PCB business card is built around the ESP32-H2-MINI-1, from the ESP32 family.

How big is the PCB business card?

The PCB business card measures 49 × 74.9 mm, has 4 copper layers and is 1.66 mm thick.

How many components are on the PCB business card?

301 components, from 36 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 PCB business card design files?

From the fab-pie/workshop_kicad_2 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 PCB business card design in my own project?

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

Can I test firmware for the PCB business card without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
