Tiny ADS Interface is a DIY diagnostic interface for older BMWs. It is the continuation of the almost free ADS interface. Or at least, it was meant to be. More than a year after the almost free ADS interface was released, people were still asking for a prebuilt interface and I still had nowhere to send them. So I decided to do an actual PCB layout. I went ahead and touched up the circuit some in the process, adding LEDs and some protection. One thing led to another and what was produced was a completely redesigned interface which is no longer true to the "discover and build it in an evening" concept.
It is, however, an ideal design for being produced in quantities of one to hundreds. I hope to be able to build these cheaply enough to provide a viable answer for the people wanting a DIY interface without the DIY assembly.
Of course, others are encouraged to download and build the design too. If you want something more durable than an almost free ADS interface and you want to build one yourself, this is a great option. You can send the gerbers to OSH Park, order the parts from Mouser, and assimilate some SMD assembly tutorials while you wait for the PCBs to arrive. Once you have everything you need, you should be able to assemble your Tiny ADS Interface in an afternoon if all goes well.
