The base of this module is CY8C9560A IO extender chip. A single socket from mainboard will add 60 inputs/outputs with interrupt capability. Also, 16 of these pins can be PWM signals. The signals with PWM are exposed on header-placement so it is easy to add standard RC servo motors. Adding 16 servo motors was never easier.
It is possible to add up to Eight of this module on one socket with minor hardware changes. See schematics under downloads and CY8C956A datsheet for further details.
Requires socket type X
.NET Gadgeteer compatible cable is included.
