WFM50-SFC201 is a “Serial to Wi-Fi” standalone module with the size of 28.0 x 18.0 x 2.7 ㎣. It consists of
chip antenna, X’tal, 4MB serial flash, Tx/Rx switch, U.FL connector and passive components. 
The device requires no operating system and has a complete TCP/IP stack that only requires a simple AT
command set to establish connectivity for your wireless
product. WFM50-SFC201 supports SPI, UART and
SDIO 2.0 interface with network and security protocols. All related software and
documents are provided to
users and on-line technical support system is available. The device is the best solution for
IoT(Internet of Things)
device and simple system like as small home appliance and healthcare goods. It is available in a SMD
(Surface Mount Device) type that is easy to layout.
