Introduciton
HLK-RM65 is a high-performance embedded WIFI6 AX3000 module launched by Hi-Link Electronics, which is highly integrated the on chip system wireless network router module uses the MT7981B+MT7976C+MT7531A scheme, with a theoretical maximum wireless speed 574Mbps+2402Mbps. Used for high wireless performance, home entertainment, and home automation.
The SoC used is manufactured using advanced silicon technology and integrates dual core ARM ® Cortex-A53MPCoreTM, working up to 1.3GHz frequency and more DRAM bandwidth. It also includes various peripherals, including SGMII and USB3.0 (host) port. two 2.5Gbps HSGMII Ethernet interfaces have also been implemented. MT7981B, combined with RF chips, can provide
the WIFI6 AX3000 wireless router platform provides a dual frequency concurrent chipset solution.
