Description
This I/O expansion board is designed for Arduino Nano microcontrollers, breaking out pins into convenient 3-pin headers for rapid prototyping. It provides dedicated servo-style connections, analogue power breakouts, and I2C ports to simplify project wiring. It is an ideal companion for students, hobbyists, and makers building sensor-rich robotics and automation projects.
Versatile pin breakouts
The board breaks out 14 digital I/O pins into 3-pin servo-style headers with dedicated ground, power, and signal lines. It also includes 8 analogue pins with integrated power and ground rails, as well as 6 PWM-capable pins.
Expansion and power options
Featuring 5 I2C expansion headers, this board simplifies connecting multiple I2C sensors and displays. It also provides dedicated AREF and 3.3V outputs alongside a dedicated servo power input.
Form factor and compatibility
Designed for a snug fit with Arduino Nano V2.X and V3.X development boards, it measures 57x54mm for easy integration into compact project enclosures.
