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

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

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

Compact-CS-UART is a client / server type Wi-Fi module.

This means that it is able to autonomously connect to a server, also public, and communicate with it. It can simulate a wire cutting between two devices used combined with a Compact-S-UART module.

Compact-CS-UART is a complete and fully certified module that offers a quick, easy and cost effective solution to OEMs to enable Wi-Fi connectivity into their systems.

The module is an IEEE 802.11bgn device that directly provides a wireless interface for data transfer and control of equipments. It integrates WLAN protocol and configuration functionality to make a fully WLAN solution.

It permits ad hoc and infrastructure mode to create itself a wi-fi network or to connect to an existent access point.


Compact-CS-UART makes a serial UART (RS232 without transceiver) connection and two digital I/O pins available, configurable as input or output, propagated directly to Wi-Fi.


The device is ready to be connected to a cloud solution, like Sense Cloud, to share data all over the world by the Internet.


The Compact-CS-UART modules are immediately ready to be used. Thanks to Wiicom configurator software, 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.

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.
