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 BLE, 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.


  • ESP32 Dual-core Tensilica LX6 microprocessor
  • Up to 240MHz clock frequency
  • 520kB internal SRAM
  • Integrated 802.11 BGN WiFi transceiver
  • Integrated dual-mode (classic and BLE)
  • 2.5 µA deep sleep current
  • 28 GPIO
  • 10-electrode capacitive touch support
  • Hardware accelerated encryption (AES, SHA2, ECC, RSA-4096)
  • 4MB of FLASH memory (32 MBit)

Additional features for ESPea32

  • CP2104 USB-Serial converter onboard with 921600 max baudrate for speedy uploading
  • Auto-reset support for getting into bootload mode before firmware upload
  • 2 mounting holes
  • Reset button & flash button
  • Breadboard friendly
  • Two optional sizes
    • whole size - 25.8mm * 51.28mm
    • cut off size - 25.8mm * 33.56mm

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:
