Board Features

Both v3 and v4 boards features:

• Oil pressure warning light (red)
• Neutral light (green)
• EFI warning light (yellow)
• Low fuel light (blue)
• Support for displaying the water temp from the the stock water temp sensor
• Ability to decode error codes from the SV650 ECU *
• TPS adjustment indicator *

[*] Note: Normally the 4 digit LED display shows the water temp. To show the TPS indicator or ECU error codes, you’ll need to use a “Suzuki diagnostic tool” (aka a paperclip) to short two wires per the shop manual.

The v3.0 and v4.0 boards have some small differences:

1. v3 is all through hole (PTH) while v4 has some SMD parts.
2. v4 adds circuit for detecting bike battery voltage
3. v4 adds a solder pad for the LM7805 to improve vibration resistance (Note: I highly recommend you glue the LM7805 to the PCB on the v3 board as vibration may cause metal fatigue and cause the part to break.)

Ordering the PCB's

You can order the boards directly from OshPark if you don't have your own PCB fabrication house:
