Welcome to Hi-Link store.Shenzhen Hi-Link Electronic Co., Ltd was founded in 2009.
It is a high-tech enterprise focusing on WiFi module, Bluetooth module and power module, integrating R & D, production and sales services.We are committed to making each intelligent product more convenient, faster and more reliable and providing customers with safe, high-quality and reliable products is our eternal pursuit.HLK-7621A
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.Features
