Ultimate Relay Card
Ultimate Relay Card Connections
- The RF input is the RFI pin of the 2 x 5-pin header on the left of the board (same as in the Low Pass Filter kit usage)
- RF output from the connections circled in yellow (in jumpers section below)
- An alternative is to cut the track from the SMA connector center pins and add a wire to connect it to the common bus track that runs horizontally across the board, finishing at the "RF" pad circled in yellow
- Cut/Jumper
- Cut on top side near Vertical SMA
- Jumper on rear side
- Jumpers

Testing
- Apply 9-12V to DC jack
- Use LED w/ resistor on output to check 5V
- One channel at a time
- Pull up channel input to +5V
- Check output with LED pulled up to +5V out
