XK-1 3.3V and 5V output question

[landon]

For the 3.3V and 5V pins on the XK-1 expansion headers, what current draw can I expect to get from those? I don't see it spec'd anywhere in the manuals.

I have a device I want to power with the 3.3V output, if possible, or 5V if need be, that is around 250ma.

Thanks,

Landon

5V has no regulator on it so you can draw as much as you want there, but the 3.3V i think has a LDO so i wouldn't draw more than 300mA from that.

It just comes down to putting your finger on the regulator and see if its hot.

The XK-1 can supply 180mA on the 3.3V line
