802.11 b/g/n Wi-Fi OEMs Module, Tx-Rx, Server Type, 2 Pin DIG I/O, Pin Reset

Ordering Code: CMP-R-S01-S[add_to_cart sku=CMP-R-S01-S]

The Compact-S-UART is plug-and-play stackable Wi-Fi module. It is a serial Uart to Wi-Fi Converter.

The Compact-S-UART is server type Wi-Fi module. It is characterized by the capability to create a Wi-Fi network with its own IP factory editable and allow other Wi-Fi devices to connect to it.

Just a few configuration steps a quick and easy process, using our SW-Configurator issued free of charge to transfer and receive signals from the UART port of the host device and the wireless network TCP/IP.

Compact-S-UART is a module of very small dimension (42 x 23 x 5 mm), characterized by a very low power on which a TCP / IP module, a micro processor and an antenna are incorporated.

Thanks to its compact size and extremely low power consumption, it is perfect for mobile applications such as wireless activity monitoring, sensors and portable devices battery. With modules Compact-S-UART implements the concept of Internet-of-Things.


Compact-S-UART makes easy the connection to a machine with an UART (RS232 without transceiver) interface, directly to a Wi-Fi network. Compact-S-UART is also equipped with two digital I/O pins, that are configurables as digital Input or Output.


The Compact-S-UART modules are immediately ready to be used.

Thanks to Wiicom configurator software (Compact Ready Go), available on wiicom website, user can define all Wi-Fi network settings.

There’s no need to develope or modify any software on the host board.


Wiicom offers to the evaluator a PWR-F-RS232 board, which together with your Compact-S-UART in a few minutes, industrial devices will connect on Wi-Fi, eliminating time hardware and software development.

Through simple accessories it's possible to evaluate the features and performance of all modules WIICOM Family Compact, linking them to various interfaces on board electrical devices for industrial use, handling analog signals, digital signals and the most common data bus.
Electrical Interface RS232 0-5V / 0-10V / 6-28V (with accessories) / 0-20mA / 4-20mA (with accessories)
Data Protocol MODBUS
Connectivity Wi-Fi is ready after few configuration steps using an intuitive PC-interface (available for Windows and Linux OS). The accessories currently available matching family of Compact modules are the following:

Strip Adapter 8-pin

The Strip Adapter 8-pin module is used to immediately connect the Compact-Family modules to customer's device. Strip 8-pin Vertical, 8-pin Horizontal and 8-pin with holes are available.


The PWR-F-RS232 board is used to transform the Compact-UART into an RS232 compatible Device.
