SUB-20 Interface Board
Posted: Mon Jun 03, 2013 2:23 am
I have designed an I/O board for the SUB-20 to plug onto. It makes the 32 GPIO selectable as inputs or ouputs with the flip of a switch. When selected as an ouput the interface pervides increased drive via an op-amp. It also supplies overvoltage protection for the SUB-20 GPIO. There are 16 analog Ouputs capable of operating from +10V to -10V. These outputs are pretty slow moving so they are not good for generating wave forms but are exelent for providing steady state voltages across thier range with op-amp drive circuits. The interface board provides overvoltage and filtering/scaling circuits for the 8 analog inputs as well. Lastly it has a small protyping area for building additional circuits.
I have been thinking about producing these boards for sale if there is any interest in them. So let me know if you think you would be interested in having one of these assemblies or have questions.
