Mercusy is another subsidiary of TP-Link for budget wireless devices such as wireless access point and router devices. I seen this Mercusy MW301R 300Mbps cheap plastic case budget router with the price tag of 495Php online its around 10USD if we convert that from Philippine peso. The MW301R is so tiny more or less a clone of TP-Link WR820N v2.0 except that the flash of WR820N v2 is 2Mb whereas SoC and RAM exactly the same including the LAN/WAN ports.
MW301R is equip with MediaTek MT7628KN SoC a single core 570MHz processor, RAM is not expandable it is built-in inside the SoC its 8MB whereas FLASH can be replace with any 8pin chips such 25Q series flash chip.
I buy it for the purpose of its small form factor that I can turn it into OpenWrt IoT, I thought it was just like WR701N and WR703N were you can just desolder the RAM and the FLASH and replace it with higher capacity so OpenWrt will work with full functionality. It was a mistake because during my purchase of this Mercusy devices I can not find any docs on Google.
The only possible thing about this MW301R is upgrade the RAM with 2Mb flash and replace with TP-Link firmware to make it WR820N v2.0 which support the following WISP, AP with smart DHCP, Reapeter or Extenbder. With Mercusys firmware MW301R this device is limited to WAN PPPoE, Dynamic and Static IP only. It has WDS but the range is not that power as such MT7628N SoC like WR840N and WR841N.
Upon testing on the wireless access point I plug my 100Mbps fiber optic connection to the WAN ports it can only gives me around 25Mbps, direct connection on the LAN ports about 39Mbps only. Not bad for the price tag 495Php if you intend to use it at home for limited user for less than ten users only.
Serial port is present on the circuit board its labeled with Tx, Rx and Vcc. USB port can be moded if you wish to have one for some purposes docs is available online.

How to flash WR820N firmware into MW302R. Both of them has same hardware specs.
why you want to flash your WR820N with MW302R firmware? is it mw301R or MW302R?
TP-Link WR820N can be flash with MW302R firmware or vice versa you need a USB-serial.
these two router has only 8MB RAM DRR2? other routers that have the same price have 64mb ram.
