Hello,

We need to interface a sensor (TI ADS1298) to the EB013 and need some assistance. The chip requires both 5v and 3.3v in order to work properly. I would like to find out if there is somewhere I can get the 3.3v from either the eb006 or the eb013.

Thanks!

Hello,

Im afraid that there is no 3.3V source on the two E-blocks you listed so you will probably have to use your own regulator with the system. Maybe the Patch or prototype boards would help you to do this.

There is a good schematic here for converting your I/O to voltages that are compatible with the 3.3V spi device using a regulator and some potential dividers.

Thanks for the info.
