Wi-Fi 802.11 b/g - for microcontrollers

The Type VK module is based on Texas Instruments CC3000 chipset supporting the IEEE802.11 b/g standard for WiFi connectivity.  This module is tailored for operation on low cost, low power microcontrollers.  What distinguishes the Type VK module is the network stack, driver, firmware, and supplicant are resident on-module stored within memory.  The type VK module is intended for broad market use by incorporating peripheral hardware functions on-module to simplify customer implementation.  The modules dimensions are 16.5 x 11.5 x 2.2 mm.  WLAN host interface is implemented through SPI.

Platforms

The Type VK module interfaces to microcontrollers beginning with TI MSP430.  In addition, support for other popular microcontrollers will be introduced to the market as they become available.  The Type VK module is also packaged on the Type VK EM-board form factor for easy plug-in to the MSP430 and TI Stellaris microcontroller development boards.  These two development platforms serve as the reference point from which customers can port to other microcontrollers.

Frequently Asked Questions for Type VK

Q: What are the differences among hardware revisions? 

A: The initial shipments of EM boards used an earlier hardware revision. A 2k ohm resistor was used for R8 as shown on the EM board schematic. This hardware revision contained a label showing black text on a white background. May 2012 shipments were hardware revision ES2.1. This module can be identified by its laser marking on the module shield, marking is the characters ES2. The resistor R8 is not needed for this hardware. Please use zero ohm resistor or implement as a short circuit, R8=0 ohms. The production version module is configured the same as the ES2.1 version.
