README
README.mdESP32-devboard
I made this ESP-32 Development board to learn KiCad. It is heavilly based on the ESP32-DevKit C reference implementation, but with the redundant micro USB port replaced with USB-C. Here's a ray-traced KiCad render:
Usage
This repo comes with the footprints, 3D models and everything needed to reproduce the renders. Also, this KiCad project uses the KiKit extension to create the below panelization in a format compatible with the JLCPCB PCBA service.
The resultant production files are here. If you want to edit the design you will have to re-create the panel and gerbers for production:
- Setup KiKit
- Open an empty KiCad pcbnew instance
- Click on the KiKit icon to open the GUI.
- Select the updated pcb design and output directory (I used
/panelized) - Import my KiKit JSON config
- Panelize!
If you then decide it's good enough for production, run the following snippet to get the gerbers, specifying the path to the panel.
kikit fab jlcpcb --nametemplate "ESP32_panelized_output{}" --no-drc --assembly --schematic <path to schematic file> <path to PCB file> <path to output directory>This will produce gerber, drill and position files for JLC PCB.
Previous revisions:
The PCB did not work on first try because of two misconfigured 0ohm DNP resistors on the USB serial traces. As a result I had to solder two strands of solder wick directly to the serial converter chip and ESP32, and hold them in place with copious quantities of tape.

Questions
How big is the PanelizedESP32 PCB?
It measures 204.3 × 75.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the PanelizedESP32 use?
491 parts, built around the AMS1117-3.3, LESD5D5.0CT1G, SS8050-G and TS-1187A-B-A-B. 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 PanelizedESP32 KiCad files?
From the valeriyproklov/ESP32-devboard repository on GitHub, at the commit this page was made from: the board is panelized/panelizedESP32.kicad_pcb and its schematic ESP32-devboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PanelizedESP32 design in my own project?
Its repository publishes it under the CERN-OHL-P-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).
