RF-WM-11AFB1 is a wireless module based on Realtek RTL8711AF. The module integrates WLAN MAC, a 1T1R capable WLAN baseband/RF and NFC functions. Its main MCU 166 MHz ARM® Cortex™-M3 and the bigger ROM/RAM/flash resources make it possible to deal with a large quantity of data. Its RF option enables the module in applications to have a chance to reach different ranges and reduce the end product RF development work. The module also supports the serial port transmission and AT commands to set the parameters. The protocol supports AP mode, Station (STA) mode and AP+Station mode.
