About this board
The ESPino (also written as ESPino ESP-12 or ESPino ESP8266) is a compact, breadboard-friendly development board built around Espressif's ESP8266 on an ESP-12 module. It integrates an onboard 3.3V regulator, a CP2104 USB-to-serial bridge with a micro USB connector for easy programming, an RGB LED, and two buttons for prototyping. Its built-in Wi-Fi makes it well suited to IoT, home automation, and connected sensor projects. In this guide, you'll find the ESPino pinout, datasheet, technical specs, and setup instructions.
- Operating Voltage: 3.3V
- Input Voltage: 4.4 - 15V
- DC current per I/O Pin: 12 mA
- Max. DC current for the 3.3V Pin: 800 mA
