Device specifications:
* Qualcomm/Atheros QCA9533 v2
* 650/600/217 MHz (CPU/DDR/AHB)
* 64 MB of RAM
* 16 MB of SPI NOR flash (mx25l12805d)
- 2x 7 MB available; but one of the 7 MB regions is the recovery image
* 2x 10/100 Mbps Ethernet
* 2T2R 2.4 GHz Wi-Fi
* multi-color LED (controlled via red/green/blue GPIOs)
* 1x GPIO-button (reset)
* external h/w watchdog (enabled by default)
* TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX)
* 2x fast ethernet
- eth0
+ Label: Ethernet 1
+ 24V passive POE (mode B)
+ used as WAN interface
- eth1
+ Label: Ethernet 2
+ 802.3af POE
+ builtin switch port 2
+ used as LAN interface
* 12-24V 1A DC
* internal antennas
Flashing instructions:
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the factory image to the u-boot when the device boots up.
