A bit of a back-story of how this project came to be.
Sub if you like what you see.
Project Structure
The project consists of
- Firmware
- Hardware
- Mechanical
- Scripts
These are structured into their own files. I could have used submodules, but decided against it.
1. Firmware
Code for the business card. This lives on the ESP32
Requirements
- ESP32 IDF version 5.4
- Target set to ESP32-H2
- BLE configured to NIMBLE
2. Hardware
Schematic
PDF schematic included for your viewing pleasure.
PCBs
All the gerber files you'd need to send to a fab house.
Kicad
All the files you'd need to expand and work on this further. If you'd like.
3. Mechanical
Enclosure
All the step files you need to make one of these. Extrusion printer works well for this part.
4. Scripts
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
Requirements
A bunch of pip packages
What the project could use
- Cleanup, but thats true for almost anything out there
- A proper graphics library -- Adafruit, or even LVGL
- Scripts that would show stock data. anyone?
If you take it further
Let me know if you ever make one of these, I'd love to see it. Seriously, that'd be exciting and inspiring to keep making my projects open source!
Known issues
- Switch requires to be shorted due to power consumption at run time
- GPIO 1 as is does not allow the device to wake up from sleep
- The LEDs seem to be pulling a lot power even when ESP32 is in deep sleep mode

Special Thanks
Thanks to Michael Angerer for his open sourced esp32_ble_ota project. I used it to get BLE running in this project. His blog post and github repo are a great resource. Check it out. https://github.com/michael-angerer/esp32_ble_ota

Questions
How big is the PCB business card PCB?
It measures 49 × 74.9 mm and has 4 copper layers, 1.66 mm thick.
What parts does the PCB business card use?
311 parts, built around the ESP32-H2-MINI-1U, MCP73833, IN-PI15TAT5R5G5B and BSS138. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the PCB business card KiCad files?
From the StuckAtPrototype/PCB_business_card_remake repository on GitHub, at the commit this page was made from: the board is hardware/PCB_business_card.kicad_pcb and its schematic hardware/LED_Display.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB business card design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
