Except for having a hard time finding official specs and documentation, this seems quite robust. Dial in your vref before using because mine were WAY off the recommended 500mv (by a factor of 3 or 4). To use with 24v systems, remove D1 and run the output of a buck regulator to the right pad where D1 was. Dial the buck to around 6 or 7 volts to feed the Mega board's regulator and everything works perfectly.
