TP-LINK RE210


 * Product page

"2053500117" is silkscreened on the board in the FCC photos.
 * Hardware appears to be very similar to the Netgear EX6100.

Unit has internal power supply and plugs directly into mains power socket.

Stock firmware only functions as an extender and client bridge and does
 * not support access point mode.

Basic details
To get the unit open, remove the two screws at the top. Squeeze the case in the middle
 * of each side t help loosen the two clips that continue to hold it together.

It takes some force to separate the two halves, but be careful not to damage the short
 * the antenna cables when the case finally gives.

There is a ceramic heatsink on the CPU - you can remove this to inspect it by giving
 * it a twist. It will remain adhesive so can be re-attached when finished.

Pinout

 * J1 is a serial header. Pin 1 is closest to the top
 * of the unit and pin 4 closest to the Ethernet port.

The pinout is as follows: © 1 - Tx © 2 - Rx © 3 - Gnd ® 4 - Vcc Connect with settings 57600 8N1. Signalling voltage is 3.3v.
