mountable Wireless Access Point, which is powered over PoE.
Hardware:
	- SoC: Mediatek MT7621DAT
	- RAM: 128MiB on SoC
	- Flash: 16MiB GigaDevice GD25Q128C
	- 2.4Ghz Wifi: Mediatek MT603EN
	- 5GHz Wifi: MT613BEN
	- Ethernet:
	  - 1x 1GBit WAN port, passive PoE capable
	  - 2x 1GBit LAN ports
	LEDs: 1x Bi-Color LED (red/blue)
	Buttons: 1x Reset Button, 1x Power Button

Installation:
	Power on the access point and immedately press the reset
