  • Product WIG-09555 | about 2 years ago

    Dunno if it helps or not, but I’ve made a very small version of the above (well some differences actually), but it still uses the STN1110 chip instead of a ELM327. All hardware is open source. The module itself has a very low power mode enabling you to leave it plugged into your car for very long periods of time. Schematics and PCB files are downloadable from my site here: http://batman.homelinux.com/blog/bluetooth-obdii-adapter/

    I also have older, downloadable designs based on the ELM327, but the STN1110 is a superior chip.

    Hope this helps!

    This is definitely a fantastic BT module to use. It pairs easily w/ Android, Windows Mobile, Windows..etc. Haven’t tried it w/ an Apple product though.

    If anyone needs RN-42 breakout boards, a board that supports a PIC24F micro along w/ the RN-42, or vehicle OBDII Bluetooth interface modules, check out the ones I’ve designed here: OBD-II Bluetooth Adapters The adapters are open source, hackable, and Altium sources are available on the linked page!

    I'e designed a few OBDII adapters using this connector and the RN-42 module Sparkfun sells (used to be the BTM-182). You can connect to the adapter via Bluetooth. There are STN1110 and ELM327 versions available complete w/ gerbers and Altium source.

No public wish lists :(
