Re: TI and future Jaguars

Here is a concept of a modular controller that was inspired by the system used for arduino 'shields'. The stack is fed power from the bottom up, with high power circuitry at the bottom on one module, this eliminates the need for high current connectors between modules. The fan is mounted just above the high current module to cool the MOSFETs. The low-current section of the stack is mounted above the high current module and fan with a gap for air flow. The signal (from the cRIO) is fed from the top down, this separation of power and signal inputs helps reduce noise. the processor is on the bottom. In some configurations, this could be a simple PWM H-bridge driver, in a CAN application, this would actually be a micro controller/processor. It is designed to accommodate 2 input modules that are each half the width of the other modules (so they occupy the same layer in the stack). One of these would be the pwm header or CAN interface. The other is for encoders, limit switches, potentiometers, hall-effect sensors, etc. On top is the auxiliary output. This is for status indicator lights and error reporting.
