MT7621A wifi module OpenWRT 300mbps router
1.General
The GS-RME5000-V1.0 module use the MT7621A chipset.The MT721A integrates a dual-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.

9. Precautions before surface mounting:
1> When customers Open stencil ,they must be sure the hole enough bigger to the module plate, please press 1 to 0.7 mm is widened to open outward and the thickness of 0.12 mm .
2> when we need get the wifi module ,we can't Direct hand and must wear the gloves and static ring.
3> According to the size of the customer ‘s the mainboard ,the furnace temperature can stick on a tablet standard temperature of 250 or so up and down no more than 5 degrees and sometimes it even can achieve 260 or so up and down no more than 5 degrees .
4> Storage and use module control should pay attention to the following matters:
a. The calculated shelf life in a sealed bag is 12 months ,stored between 0 °C and 40 °C at less than90% relative humidity (RH).
b. After the bag is opened, devices that are subjected to solder reflow orother high temperature processes must be handled in the following manner:
> Mounted within 168 hours of factory conditions, i.e. < 30 °C at 60% RH.
> Storage humidity needs to maintained at < 10% RH.
> Baking is necessary if the customer exposes the component to air for over 168 hrs, baking conditions: 125°C for 8 hours.
