TP-Link TL-WR843ND

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version (18.06 or later) onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device will end after 2019.
19.07 will be the last official build for 4/32 devices. After 19.07, no further OpenWrt images will be built for 4/32 devices. See OpenWrt on 4/32 devices what you can do now.

Very similar router as WR841ND just with POE support.

There is a topic about this router (google translate it):

Working images (tested wifi multi-net, bridge networking — AA 12.09) here: — seems to be 841ND's with id modified.

:!: Warning! Be aware of input filter caps, which are rated only for 16V! (at least on v1.5), so 15V is absolutely maximum for PoE powering of this router

Main difference is that this router has 34063 UM-G1 445TA8 DC voltage regulator whose specifications show 40V DC as maximum allowed voltage, but recommended maximum voltage is 36V. So you can power this router with wide range of voltage: 5-36V DC.

Here is an image of DC voltage regulator:
