Dear all,
·
Is that anyway to increase Stamp2’s IO power supply from current 5V to 6V·~ 10V such as add in some capacitor or other external circuit board?

Efly.

    No. The BS2 is based on a "PIC" processor, so the voltage at its I/O pins is "TTL", or +5 or zero volts.

    Having said that, I believe you can use a Darlington Array chip to switch higher voltages.

    There's a section in the "Industrial Control" tutorial manual on controlling motors, solenoids, and relays with a Stamp using external switching transistors.· Look under the Resources tab on the main Parallax webpage, then select Downloads, then Stamps in Class Downloads and you'll see the list of tutorials.
