RN-131 Evaluation Kit (RN-131-EK)

The RN-131-EK is an 802.11 b/g Wi-Fi evaluation kit for the RN131 module that can be used to quickly add Wi-Fi connectivity to embedded applications. It has the flexibility to connect directly to a PC via a standard USB interface or to embedded processors through the TTL/UART interface. The board also includes 2 convenient push buttons for controlling both SoftAP and WPS (Wi-Fi Protected Setup) mode without software configuration. The status LEDs and jumpers enable rapid prototyping and integration into existing systems.

The RN-131-EK supports the evaluation of projects planning to use the RN131 module. The RN131 module incorporates a 2.4 GHz radio, processor, full TCP/IP stack, real-time clock, and supports the FTP client, DHCP, DNS, and HTML client protocols. The module supports ad hoc and infrastructure networking modes along with SoftAP mode.

The RN131 module is programmed and controlled from a console with a simple ASCII command language. Once the configuration is set up, the module can automatically scan to find an access point, associate, authenticate, and connect over any Wi-Fi network. Additionally, the module can automatically wake up, send data to a remote host, and go back to a low-power sleep state.
