The Presto–Changeo board is
designed to crossfade LEDs or any controllable source.
1x 9V Battery Clip
1x 2.1mm DC Adapter Connector
1x Trigger Input (+,-, and Trigger like Parallax PIR)
2x PWM channels (Front and Back, screw terminals)
1x Trigger passthrough (whatever trigger signal is input to the
controller can be daisy-chained to another board)
Size: 2.25" x 1.35"
Power: ~200mA @ 9Vdc
The outputs for the front and back are just PWM going from 0% duty cycle
to 100% duty cycle and vice-versa. They are 5V and can supply up to
about 200mA when at 100% (At full brightness). Frequency measurements
put the PWM at about 120Hz.
The trigger port is also 5V. It is not a dry trigger.
EFX-Tek sells a great PIR for this.
