11 b/g/n/ax [Air rate]： 150Mbps [Product size]： 16*24mm [Introduction]： E103-W11 is a cost-effective serial to Wi-Fi module, small size package, working in the 2

4~2

4835GHz frequency band

The module can use the serial port to send and receive data, which reduces the threshold for wireless applications
