high quality openwrt wireless MT7621 MT7623 AR9344 wifi module board
The Oolite V9 is a highly integrated and feature-rich IEEE 802.11n 2x2 2.4/5 GHz system-on-a-Chip for advanced WLAN platforms. Which supposes 802.11n operations up to 144 Mbps for 20 MHz and 300 Mbps for 40 MHz respectively, and 802.11a/b/g data rates. It includes a MIPS 74Kc processor, PCI Express 1.1 Root Complex and Endpoint interfaces, five port IEEE 802.3 fast Ethernet Switch with MAC/PHY, one MII /RMII/RGMII interface, one USB 2.0 MAC/PHY, and external memory interfaces for serial flash, SDRAM, DDR1or DDR2, I2S/SPDIF-Out audio interface, SLIC VOIP/PCM interface, two UARTs and GPIOs that can be used for LED controls or other general purpose interface configurations.
AR8327 The AR8327 supports many operating modes that can be configured using a low-cost EEPROM and /or the MDC?MDIO interface. The AR8327 also supports a CPU header mode that appends two bytes to each frame. The AR8327 contains a 2 K-entry address lookup table that employs three per bucket to avoid hash collision and maintain non-blocking forwarding performance. The table provides read/write accesses from the serial and CPU interfaces; each entry can be configured as a static entry. The AR8327 supports 4K VLAN entries configurable as port-bases VLANs or 802.1Q tag-based VLANs. The CPU can be detected frame with header to configure the switch register, the address lookup table, and VLAN and receive auto-cast MIB frames. The sixth port(port5) supports a PHY interface as a WAN port. The first port (port0) supports a MAC interface and can be configured in MII_PHY or RMII_PHY mode to connect to an external management CPU or an integrated CPU in a routing or xDSL engine.
