DC Specs on Parallax Products

Harbor

I am doing a power budget on my current project and I can't seem to find the DC specifications page for items like the BS2P and the LCD appmod (#29121). I've estimated the PINK at 100 mA based on some docs for the earlier Parallax product from Red... somebody, but I'd like to confirm that also if I can. Could someone give me a link to the right pages for this information?

Harbor -

The Stamp Comparison guide listed at the location below, will give you the power consumption figures for all the Stamp platforms:

I can't help you with the LCD AppMod, as the only reference I can find would indicate less than 1 mA, and I find that rather doubtful. Minor additional current will be drawn if any of the buttons are pressed.

Regards,

Bruce Bates

The Pink requires about 160 mA at 5V, according to the comments from Chris Savage at http://forums.parallax.com/showthread.php?p=583990

That's just the page I was looking for, Bruce. Thank you. Couldn't seem to find it.

And it's reassuring to see that Chris had to go measure a PINK in the lab, Forrest. I thought I was missing something obvious when I looked over all the documentation several times and still couldn't find the power figures for the PINK. Thanks for finding that post.

To summarize for anyone reading this thread:

PINK = 160 mA. This would be the usual "typical" value from a DC spec, since Chris measured a running unit. If needed, the "max" value should not be more than 200 mA and probably less, because the PINK is just a micro-p running a comm protocol stack. I may be overlooking something, but I can't picture any high draw activities that might converge to create an especially high max value.

BS2P40 = 40 mA running, plus whatever draw you take from the pins (within the permissible limits of course).
