Schematic for BS2P Demo Board

Archiver

Does anyone know where I can get the schematic of the new BS2P demo
board? Looked at Parallax and could not find one. I am trying to see
which pins connect to the I-Button Socket etc.

None. When using the iButton socket or RJ-11 connection you must add a
jumper wire between the Stamp and iB1 or iB2 sockets. If you're using both
on the same Stamp pin, you only need enable one pull-up.

But ... I've found that some wires (long, small) connected to the RJ-11
require a stiffer pull-up. In this case, simply remove the pull-up jumper(s)
and use a smaller resistor -- 1 kOhm usually does the trick.
