Microduino™ MicroWrt Core

The MicroWrt Core is a cheap and small development board based on the MediaTek MT7620A SoC (which integrates Ethernet networking and 2.4 GHz WiFi 2T2R), with 64 MB of RAM and 16 MB of flash storage, built by Microduno™. The device consists of a board with the SoC, a µ-USB plug, 2 antenna connectors and two buttons, and it has 52 exposed pins. The pins are used to stack different extension boards providing diverse functionalities (Ethernet, USB, mPCI-E, etc.) and to stack a series of Microduino™ board (which are Arduino-compatible). The device is shipped with a customized OpenWrt version.
