>From what scott has said, it runs an embedded linux kernel. The Tattler, again going from what has been said in the past, is using off-the shelf hardware with a custom cable for interfacing with the car. (I&#39;d bet it is a geode w/ serial to CAN and a USB GPRS modem.) Pictures from forum <a href="http://www.teslamotorsclub.com/showthread.php/5055-New-cell-phone-app-Tesla-Tattler-works-on-all-cell-phones/page9">here</a>.<div>
<br></div><div><div style="text-align:left">There is one major advantage that the mbed has over other MCUs. Upgrading FW becomes as easy as using a flash drive. The mbed is based on an ARM Cortex-M3 (LPC1768). So, it could run linux. For what it&#39;s worth, it would be easy enough to whip up a board to go between the mbed and the simcom board that is in current use. That board could house the CAN transceivers as well. </div>
