See https://mikrotik.com/product/RB952Ui-5ac2nD for more details.

Specifications:
 - SoC: QCA9533
 - RAM: 64MB
 - Storage: 16MB NOR
 - Wireless: QCA9533 802.11b/g/n 2x2 / QCA9887 802.11a/n/ac 2x2
 - Ethernet: AR934X switch, 5x 10/100 ports,
    10-28 V passive PoE in port 1, 500 mA PoE out on port 5
 - 6 user-controllable LEDs:
   - 1x user (green)
   - 5x port status (green)

Flashing:
 TFTP boot initramfs image and then perform sysupgrade. The "Internet"
 port (port number 1) must be used to upload the TFTP image, then
