The ESPea32 is a comprehensive development platform for Espressif’s ESP32. The ESP32 is a WiFi-compatible microcontroller, but to that it adds support for Bluetooth low-energy, and more I/O pins.
What's difference ESPea32 with other ESP32 development board? It can be cut down to smaller size if you need a smaller board. The board is also part compatible with our ESPea development board.
In addition to the WiFi/BLE SoC, the ESPea32 includes an CP2104, which converts USB to serial, and allows your computer to program and communicate with the microcontroller.
Additional features for ESPea32
A USB interface that lets you quickly use it with the Arduino IDE
Both I2C interfaces are supported by the Wire library. The SDA and SCL pins are assigned, by default, to pins 21 and 22.
And the SPI library should support all three possible SPI interfaces. By default, here are the pin mappings for those interfaces:
