Microduino-Shield UNO

Language:	English  • 中文

Microduino-Uno Microduino-Uno is an extension board based on the official Arduino board, you can use it just like Arduino with Microduino-USBTTL and Microduino Core modules.

Features Compatible with the pin of Arduino Uno. Wide-voltage DC power input (8 ~ 35V) supportable. The 2.45mm (0.1 inch) pin pitch offers the base for Microduino modules and pins with the same name are connected to the base, making it easy for debugging; Uniform Microduino interface standard and rich peripheral modules make it easy to connect with other modules and sensors meeting Microduino interface standard. Specifications Wide voltage DC power input (8 ~ 35V input) supportable; 5V and 3.3V regulated power; LED indicator connected to D13 digit I/O port and lightened up with high electrical level; Onboard reset button; With serial port（RX1，TX1), I2C（SCL，SDA), power（5V，3.3V）and ground pin added； Onboard ICSP pin; Two Microduino UPIN27 bases interconnected to the board.
