Microduino-Uno

Microduino-Uno is an extension board based on official Arduino board, you can use it just like Arduino with Microduino FT232R and Microduino Core modules.

Features

• Compatible with the pin of Arduino Uno;
• Wide-voltage DC power input (8 ~ 35V) supportable;
• The 2.45-pitch female pin header offers the base for Microduino modules and pins with the same name are connected to the base, making it easy for debugging;
• Uniformed Microduino interface standard and rich peripheral modules, capable of having a fast and flexible connection and extension with other modules and sensors in accord with 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.

Development

Microduino-Uno is capable of having a fast and flexible connection and extension with other modules and sensors in accord with Microduino interface standard.

Application

You can download the program that Microduino provides to test the LED connected to D13 I/O port:

• Prepared Hardware：Microduino FT232R, Microduino Core and Microduino UNO；
• Prepared Software：Microduino provides testing program（Arduino part）and Arduino IDE（version 1.0 and higher）；
• Open Arduino IDE's Blink test program, choose the board "Microduino Core (Atmega328P@16M,5V)" and download directly. After finishing download,you can see the onboard LED flashes one time per second;
