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.\n  \n\nI decided to share it *open-source* under *Creative Commons Attribution-ShareAlike 4.0 International License*.\n\nThe 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.\n\u003c/div\u003e\n\n### Features\n\n- Expanded GPIO pins with 3.3v and GND\n- A tiny breadboard\n- Li-ion battery\n- USB charging controller\n- Adjustable voltage booster (set to 5v)\n\n- SSD1306 LCD module\n- 3V3-5V logic level shifter (4 channels)\n\n- 4 x LEDs (Red, Green, Blue, Yellow)\n- 2 x DIP switches\n- 2 x Pushbuttons\n- 1 x Trimpot (10 kOhm)\n- 1 x Active buzzer\n\n\n## Schematics Diagram\n\nYou can find the schematics diagram from *v1_schematics.pdf*.\n\n## PCB design\n\nYou 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.\n\n\u003cimg src=\"./images/pcb_fromTop.png\" alt=\"PCB - Top View\" style=\"width:90%; margin:15px;\"/\u003e\n\n## Final View\n\nYou can see some images of the final design (with the 3d printed enclosure) here.\n\n\u003cimg src=\"./images/image1.jpg\" style=\"width:90%; margin:15px;\"/\u003e\n\n\u003cimg src=\"./images/image2.jpg\" style=\"width:90%; margin:15px;\"/\u003e\n\n## Sample Codes\n\nI added a sample code for SSD1306 display, which is using Adafruit_SSD1306 library. I will try to add a few more libraries in future.\n\n----\n\nThis work is licensed under a\n[Creative Commons Attribution-ShareAlike 4.0 International License][cc-by-sa].\n\n[![CC BY-SA 4.0][cc-by-sa-image]][cc-by-sa]\n\n[cc-by-sa]: http://creativecommons.org/licenses/by-sa/4.0/\n[cc-by-sa-image]: https://licensebuttons.net/l/by-sa/4.0/88x31.png\n[cc-by-sa-shield]: https://img.shields.io/badge/License-CC%20BY--SA%204.0-lightgrey.svg\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnuwanj%2Fesp32-development-kit","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fnuwanj%2Fesp32-development-kit","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fnuwanj%2Fesp32-development-kit/lists"}
