The DWR-118-A2 Wireless Router is based on the MT7620A SoC.

- 128 MB of RAM
- 16 MB of FLASH
- 1x 802.11bgn radio
- 1x 802.11ac radio (MT7612EN)

- 1x 10/100/1000 Mbps Marvell Ethernet PHY (1 LAN)
- 2x external, non-detachable antennas
- 1x USB 2.0
- UART (J1) header on PCB (57600 8n1)
- 7x LED (5x GPIO-controlled), 2x button
