Cheap best wifi module long range long distance transmitter wireless module STA+AP mode
RF-WM-11AFB1 is a PCB module based on Realtek Wi-Fi SoC RTL8711AF of CortexTM-M3 core at 83 MHz. This module has on-chip 512 KB RAM and 1 MB flash, a pin-out of peripherals of SDIO, SPI, UART, I2C, I2S, and GPIOs. It has integrated a 40 MHz crystal, an on-board PCB antenna, and an IPEX/ U.FL connector for connecting to an external antenna. It supports 2.4 GHz 802.11 b/g/n at 20 MHz channel bandwidth with 75 Mbps maximum data rate. The module comes with a pre-programmed serial interface data communication protocol and an AT commands set to minimizes users’ effort to establish the data link to their existing MCUs or processors. It supports STA, AP, and STA + AP concurrent modes, advanced security features include Wi-Fi WEP, WPA, WPA2, and WPS2 with MD5, SHA-1, SHA2-256, DES, 3DES, and AES security engines.
