Description
MT7621A Wi-Fi Router Board Multi-Interface AP7621-004
AP7621-004 is a 120×100 mm Router board with MT7621A integrates a dual-core MIPS1004Kc (880MHz), HNAT/ HQoS/ Samba/ VPN accelerators, GbE switch, RGMII, Mini PCIe, USB, UART/GPIO and SDXC. The powerful CPU with rich portfolio is suitable for 802.11ac, LTE cat4/5, edge, hotspot, VPN, AC (Access Control). It can also connect to touch-panel, ZigBee / Z-Wave for Internet Service Router and Home Security Gateway.
For the next generation router, MT7621A provides several dedicated hardware engines to accelerate the NAT, QoS, Samba and VPN trac. These accelerators relieve the CPU for other upper layer applications.
