General Description The SKW92B module integrates a 1T1R 802.11n Wi-Fi radio, a 580MHz MIPS CPU, 1-port fast Ethernet PHY, USB2.0 host, I2C/PCM and multiple slow IOs. The module provides two operation modes IoT gateway mode and IoT device mode. In IoT gateway mode, the high performance USB2.0 allows SKW92B to add 3G/LTE modem support or add a H.264 ISP for wireless IP camera. For the IoT device mode, the module supports eMMC, SD-XC and USB2.0. In IoT device mode, it further supports PWM, SPI slave, 3rd UART and more GPIOs. For IoT gateway, it can connect to touch panel and BLE, Zigbee/Z-wave and sub-1G RF for smart home control. 2.
