==Features==
*Compatible with the pin of Arduino Uno;
*Wide-voltage DC power input (8 ~ 35V) supportable;
*The 2.45-pitch female pin header offers 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;
