More Information

To ease your product development we can also supply a PROton PR-25 Demo board. When the PR-25 is plugged onto the Demo board the general purpose I/O channels can be monitored by LEDs and inputs simulated using switches. The Demo board also allows some of the analogue inputs and outputs to be tested.

Another peripheral card that we can supply for the PR-25 is a proto typing board. The PR-25 controller is plugged onto the proto typing board. The developer can now add any additional hardware using the 0.1 inch grid matrix. Once the developer has tested the application Cambridge Microprocessor Systems provide a low cost fast turn round design service to integrate the extra hardware to our PROton controller.
