Product overview
The Whadda WPB109 ESP32 development board is a comprehensive development platform for Espressif’s
ESP32, the upgraded cousin of the popular ESP8266. Like the ESP8266, the ESP32 is a WiFi-enabled
microcontroller, but to that it adds support for Bluetooth low-energy (i.e BLE, BT4.0, Bluetooth Smart), and 28
I/O pins. The ESP32’s power and versatility makes it the ideal candidate to serve as the brains of your next IoT
project.
