TI Breakout Board - Wattson®

Wattson® is the ultimate power monitoring tool for development kits.  

This adapter enables real-time power monitoring for Texas Instruments AM1808, AM3517, and OMAPL138 EVMs using the Logic PD Wattson® software.  The Wattson® software is available for download from the EVM download page on the Logic PD website here.

The adapters are sold as pre-assembled boards so you can plug-n-play out of the box.  No soldering required.  We recommend purchasing one adapter per EVM.


How does it work?  The Wattson® adapter attaches to the EVM

baseboard and to a PC using a USB cable.  The EVM has multiple ADCs that monitor different power sources.  The Logic PD Wattson® software reads the EVM ADCs through the Wattson® adapter.  The Wattson® adapter converts the PC USB signals to I2C to allow the data transfer from the ADCs back to the PC.  The Logic PD Wattson® software converts the data to visual charts and also has data logging capability.  To read more about the free Logic PD Wattson® software, please visit www.logicpd.comHere is a Logic PD video showcasing the Wattson® software.
