I decided there was one too few boards available for this project.. Not yet 100% sure if I'm going to be making them for sale yet. It's still very much in the concept stages.. Should work as is, however, I have to check some of the resistor / capacitor values to make sure they are sane..
Now for the good stuff..
I have the following features:
3 (Kessil type) PWM circuits,
6 switchable (with jumpers) 12 volt / 24 volt jacks for lights or fans. (or anything else that runs on those voltages that you want to control.
2 Dosing pumps
3 external temp probes, 1 onboard temp sensor
2 ATO jacks
1 header to break out the ULN2803A pins to DB9 or whatever to connect to an external powerbar.
3 buck converters onboard supplying 12v, 10v, and 5v.
40 pin header and mounting holes to mount on a Raspberry Pi.
slots cut for Pi camera and Pi video ribbon cables.
Needs a 24 volt power supply, mine is 100 watts and runs my development board quite nicely. Internal temp of the case is cooled by a 50mm 12 fan off of the fan header controlled by the internal temp sensor. Temp stays under 90f at all times.
Short of having it feed my fish and wash my dishes, I can't think of anything else it may need.. Suggestions definitely welcomed. (I have not sent this off to be printed yet.
