Tiny Serial WiFi Module Includes ARM Cortex M3

The Inventek Systems 802.11 b/g/n Serial to WiFi module makes it easy to add Wi-Fi to your embedded design.  It can be programmed from a host with a choice of serial interfaces using a simple AT command set.

These serial interfaces are provided by an STM32 ARM Cortex M3 processor as shown on the block diagram.  No software development is required for the STM32, the AT command set interface is resident in firmware.  This means your host microcontroller does not need a TCP/IP stack or RTOS.  This simplifies software development for your application - you only need to write serial I/O code to send the AT commands and process data.

An embedded wireless evaluation board is available that make it easy to connect the module to your microcontroller board for development of your WiFi application.  Both the evaluation board and the module are available from the Inventek Systems online store.

For more information on the module and evaluation board watch this video that includes a description of the functional block diagram above.

Variscite Adds High Performance ARM Module

Variscite offers system-on-modules, single board computers and evaluation kits with TI ARM processors.  They have recently released the VAR-SOM-4460 for high performance multimedia, advanced graphics and video applications.  It features the TI OMAP4460 with two ARM Cortex-A9 cores running at 1.5GHz.

If you don't need all that power and are looking for a low cost module, Variscite also offers the VAR-SOM-AM35  starting at $49 with a TI 600MHz Cortex A8.  It features a CAN bus controller and targets industrial and automotive applications.  It supports Android, Linux, Windows Embedded CE and Windows Embedded Compact 7.
