802.11 b/g/n Wi-Fi Module OEMs, Tx-Rx, Client / Server type, 4 Pin DIG I/O, Pin Reset

Ordering Code: CMP-R-S05-CS [add_to_cart sku=CMP-R-S05-CS]

The Compact-CS-D4IO is plug-and-play Wi-Fi stackable module and digital I/O to Wi-Fi Converter.

Compact-CS-D4IO 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-D4IO module.

Compact-CS-D4IO 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-D4IO makes a connection through four digital I/O pins available, configurable as input or output and propagated directly to Wi-Fi. User can write or read PIN status.

If PINs are configured as input, Compact module will send a byte every 100msec or when PIN value changes. This byte contain PIN status.

Analogously, if PINs are set as output it is possible to change its status by sending a byte through the socket.


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-D4IO 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.

screen-dashboardcar_tabletThe Drag&Drop Dashboard (read more ...) is available bundled software to implement a customizable dashboard. Available widgets are typical environmental, automotive gauges or digital I/O and they can be positioned into the dashboard in a drag&drop way. Drag&Drop Dashboard is able to visualize a set of signals with custom widgets directly chosen by the user. With Drag&Drop Dashboard, OEMs and System Integrators will be able to create your own custom application and software prototypes for the monitoring of their devices. Drag&Drop Dashboard is available on PC version and on mobile (iOS and Android) version.
