文件:MicroWRT-rect.jpg 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 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.
