Mini Router

A mini router made using a router module with a processor of MT7628 (Ebaite E103-W20, compatible with HLK7628N).

As small as possible, using TPS54302DDCR for 3.3v power supply, resistor and capacitor 0603 package, leading out a network port (switching LAN/WAN function through switch), a 1.0mm * 4p terminal LAN port, USB2.0 interface, TF card interface, TTL serial port, antenna for ipex 1 generation

Chip solution: MT7628AN, operating frequency: 2.4GHz, transmit power: 20~ 24dBm, MCU frequency: 580MHz, communication distance: 200m, wifi protocol: IEEE802.11b/g/n.

Module Introduction: This module introduces all the interfaces of MT7628AN, supports OpenWrt operating system and custom development, has rich interfaces and powerful processors, can be widely used in smart devices or Cloud as a Service applications, and can be freely developed.

HLINK Module Data: HLK7628N

Breed firmware: breed-mt7688-reset38

OpenWrt firmware: Password: 58pp

Using lede branch, background IP: 192.168.8.1, password: 5845201314, compile parameters are as follows:

Known issue: Due to the IO of the TF card and some network ports to be reused, after flashing the TF firmware, the network port will become unusable, and the technical problem cannot be solved temporarily. As the chip is too old and the performance is not good, it can only be played with reluctantly. Here are some test pictures.
