-R4-NIC-BE14 is a 51x82mm WiFi7 module with MT7995AV supports Wi-Fi7 technology and feature IEEE802.11a/b/g/ac/ax/be compliant,2.4GHz 2x2, 5GHz 3x3 3ss, and 6GHz 3x3 3ss BE13500 Wi-Fi subsystem. The MT7995AV offers feature-rich wireless connectivity at high standards and delivers reliable, cost-effective throughput from an extended distance. The optimized Wi-Fi baseband algorithms provide superb performance. The intelligent design deploys a highly efficient offload engine and hardware data processing accelerators, which fully offload Wi-Fi task of the host processor. The MT7995AV is designed to support standard-based features in the areas of security, quality of service, and international regulations, giving end users the greatest performance at any time and in any circumstances. MT7995AV chipset 32-bit RISC-V MCU for Wi-Fi protocols and Wi-Fi offload Embedded and ROM UART interface with hardware flow control 2 PCIe 3.0 Interface, 2- WLAN:IEEE 802.11 a/b/g/ac/ax/be compliant Tr-Band Triple Concurrent (TBTC) PHY rate :up to 13700 Mbps/9500 Mbps -MIMO TX and RX -OFDMA TX and RX STBC, LDPC, TX beamformer and RX beamformee mode, mixed mode, and legacy mode Security: WFA WPA, WPA2, WPA3 personal, WPS2.0 : WFA WMM and WMM-PS How to use You can insert the -R4-NIC into CN12 and CN14 at the bottom of -R4-Main, and then fix it with two M2 screws. The -R4-NIC module requires 12V power supply, so the power supply on the -R4-Main must be turned on before powering on (SW4 is turned to the "ON" position, and the 12V LED lights up when power on) Tips:The 12V power supply be supplied to the -R4-NIC through PIN6/28/48 of the miniPCI socket. When plugging in other modules, be sure to turn off SW4 if you ot confirm whether the module can withstand 12V. Note: The board factory label
