MicroWRT

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.

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.
