I have just finished building the extension board, and, while it appears
to work all right, I can't seem to find resistor R4 on the schematic.
The power transistor near the on/off switch is getting quite hot with the
expansion board piggybacked on the Hand Board and plugged into the
charger board (on normal charge rate), and I was looking to see if,
perhaps, a resistor was shorted somewhere. I noticed that R4 does not
appear anywhere on the schematic.
Also, I BOUGHT an assembled/tested Handy Board from Douglas, and it only
seems to recognize digital inputs 0 and 1 when I use the "digital(input#)
in the Interactive C command line. This is WITHOUT the extension board
even piggybacked. Before I contact Douglas, has anyone else had this
problem?
