ESP32Breakout is an ESP32 breakout board with a lot of breakout pins (as the name suggests), for PWM servos, normal I2C connections, and more. This board is not too advanced, as it's my first dev board, but hey, it serves its purpose. This uses USB-C and a microSD card slot for code uploading, and a lithium-ion battery for powering the board (when not plugged in).
