ESP32 Development Board


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.


  • Expanded GPIO pins with 3.3v and GND
  • A tiny breadboard
  • Li-ion battery
  • USB charging controller
  • Adjustable voltage booster (set to 5v)

  • SSD1306 LCD module
  • 3V3-5V logic level shifter (4 channels)

  • 4 x LEDs (Red, Green, Blue, Yellow)
  • 2 x DIP switches
  • 2 x Pushbuttons
  • 1 x Trimpot (10 kOhm)
  • 1 x Active buzzer
