Introduction

The HLK-7621A module use the MT7621A chipset.

The MT7621A integrates aual-core MIPS-1004Kc(880MHz), HNAT/HQoS/Samba/VPN accelerators, 5-port GbE switch, RGMII, USB3.0, USB2.0, 3xPCIe, SD-XC.

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 traffic.These accelerators relief the CPU for other upper layer applications.
