MicroWRT was created in July, 2014.  

MicroWRT is a brand new development board, designed by Makermoudle for OpenWrt; 

With the MT7620A core of MIP24KEc, it is created for internet, compatible with OpenWRT;  

It supports DDR2, SD, PCI-E and I2S, equipped with 64/128MbitFlash;

It is applied in NAS, webcam, robot, OpenCV and MicroWRT;  

Here is the key: We design Microduino interface for MicroWRT, which makes it possible for you to use Microduino modules on it.  



==Feature==
*Created for the internet;   
*Small, cheap, stackable and open-source; 
*Open-source hardware circuit design and OpenWRT compatible programming development environment;  
*With H-PIN52 interface as well as extension board, it can have a fast connection with Microduinomodules;  
*2.54-pitch pin interface makes it easily integrated to pegboard. 
==History==
*Made a proof as the first edition on June 4, 2014; 

*Made a proof as the second edition on July 26, 2014; 
**Revise several bugs; 
**Change power supply scheme; 
**Add power supply indicator;  
**Change Flash packaging;

*The third edition finished on Aug. 23, 2014; 
**Introduce soft serial port, supporting I2S;  
**Design JTAG interface on the core board; 
**Change USB, UART, I2C and other pin definition; 
**Change the position of the power supply indicator.
