- 1 GB of RAM (DDR3)
- 8 MB of serial flash (SPI NOR)
- 256 MB of parallel flash (NAND)
- 2x2 2.4 GHz WiFi (IPQ6010)
- 2x2 5 GHz WiFi (IPQ6010)
- 2x IPEX/U.FL antenna connectors
- 4x 3 dBi dual-band antennas
- 2x 1 Gbps Ethernet (QCA8075) with 802.3at PoE input support
- 1x RGB LED
- 1x push-button (reset)
- DC jack for main power input (12 V)
- UART (4-pin, 2.54 mm pitch) header on PCB
