ESP32 is a powerful embedded development board. But the ESP32 DevKit design is not much breadboard friendly and has a weird pinout design. That is why I designed this development kit, to make my experiments easier with the help of built-in electronic components and breadboard.
I decided to share it open-source under Creative Commons Attribution-ShareAlike 4.0 International License.
The stickers pasted to the board also uploaded for your reference. You can print the prints/stickers.pdf file to an A5 size sticker paper and cut them.

You can find the schematics diagram from v1_schematics.pdf.
You can find the Gerber files of the design from the v1_gerber folder. This is a single side PCB, with 4 jumpers. PCB is designed using Fritzing.
You can see some images of the final design (with the 3d printed enclosure) here.
I added a sample code for SSD1306 display, which is using Adafruit_SSD1306 library. I will try to add a few more libraries in future.
