Hi everyone.· Is the new propellor based servo controller compatible with the Stamp 2pe motherboard?· I know there were communication issue·between the previous servo controller and the 2pe motherboard.· Does anyone have any experiences?

The Propeller Servo Controller is designed to work with any microcontroller that provides a 5V logic serial output. It should also work with microcontrollers that provide a 3.3V logic serial output. The Stamp 2pe motherboard can be run at either 5V or 3.3V and the Servo Controller should work either way.

The problem with the older Servo Controller was that there was an LED and some protective resistors on the serial input and a 3.3V logic signal could not trigger the serial input unless you removed the LED. This circuit doesn't exist on the Propeller version.
