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 well in NAS, webcam, robot, OpenCV;

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 Microduino modules;
  • 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.
