The OUT32 card has thirty-two 3.3 Volt binary outputs. Each output goes to pin 1 of a 3-pin header. The other two pins on the 3-pin header are tied to screw terminals.
Features:
- Thirty-two 3.3 Volt binary outputs using four FPGA pins
- 3-pin header per output
- Uses the ESPI 7474 circuit for reliable operation
- Low cost BOM
Hardware: The schematic of the OUT32 is shown below. The Eagle schematic and board files are available here: out32.sch and here out32.brd.
