Board Revisions

v4.7
  • Change footprint of D5 to be a SOD-123 for easier soldering
v4.6

This was a major update which fixes all know bugs (many which are severe) and improves the protection of the circuit. Just ordered from OshPark on 5/19/2014 so I won't be able to test it until they arrive (about 2 weeks).

  • Switch to Murata 5V switching regulator.
    • LM7805 was overheating with heavy use of LED display in latest code
  • Add power MOSFET for reverse polarity protection
  • Add TVS diode for power/spike protection
  • Fix fuel/very low fuel indicator for 03-04 and 05+
  • Move EFI light off of pin 11 to allow interrupts to work
  • Move Mode switch to an interrupt pin
  • Add ground plane & clean up traces
  • Further improve battery voltage monitoring
  • Capacitors are now SMD too
v4.1

This ended up being a pretty big failure. The mode switch is on a non-interrupt pin and the low fuel & very low fuel support will fry the Teensy. Don't use this.

  • Add mode switch
  • Add support for very low fuel
  • Improve battery voltage monitoring
  • Start using SMD components for resistors & diodes
v3.0

Generally a decent board as long as you don't expect the low fuel light to work (in fact you better cut the trace so it doesn't fry the Teensy) and don't use the LED display for more then a minute or so at a time. Otherwise the LM7805 will likely overheat and go into thermal shutdown.

  • Initial public release
  • All through-hole components
  • Low fuel warning
  • EFI warning
  • Low oil pressure warning
  • Neutral indicator
  • Displays EFI error codes and TPS sensor setting
