Tiny ADS Interface inside 20 pin connector

$63 USD

7 in stock

This is a Tiny ADS Interface stuffed inside a 20-pin connector. This thing is ready to use out-of-the-box with a serial connector at one end and a 20-pin diagnostic connector at the other end. The attached serial cable is 3 meters in length.

  • female DB9 serial connector (COM port) to PC

  • 20-pin ADS connector to vehicle

  • fully compatible with INPA/DIS in ADS mode, including battery and ignition indicators; this is not a carsoft interface

  • requires a "real" serial port, as does every ADS interface in existence; will not work with USB-serial adapters

  • fully open source - all design files, both for current and future revisions, are and will forever be freely available

  • lifetime warranty - if it ever stops working for any reason, I'll fix it for the cost of shipping

This looks so far the most neat solution to an old BMW DIY diagnostic problem. Mine is E36 M3 3.2l from 1997, hence I am not sure if this is already an OBD2 car. In any case, and confirm please if you know, even if it has ODB2 I still should be able to access it in ADS mode via that round 20pin plug, right?
Another question, I am planning to use INPA software for diagnosis, can I be sure it works well with your adapter-cable? I.e. is there any support/help should I hit the wall? (Of course I am planning to install it on a WinXP with a physical COM).

Thanks in advance for info,

Yes as long as any model has the 20 pin connector under the hood you can be sure it will work with an ads interface and inpa. Although if pin 15 is not populated in your connector then you don't require an ads interface and can use one of the many cheaper usb obd interfaces found on ebay and elsewhere. This would also remove the annoying need for the physical com port.

You can expect any ads-compatible interface to work well with inpa including this one, as bmw designed inpa to work with ads interfaces and I designed this interface to work like their original one.

There's no support from me except for the hardware itself. I'm super familiar with the hardware I designed of course, but I've never been an expert on the software and I've forgotten plenty that I used to know. I always send people to bimmerforums.com as the most useful and authoritative source of information for bmw diagnostic software that I've found. There are people there who really know the stuff well, and most questions have already been asked and answered there.

I received my Tiny ADS inside 20 pin connector. Thank you for fast delivery!
I got 2 questions:
1. Is ExpressCard rs232 adapter worth to try? wiki says it's USB related so might fail as usb-com.
2. COM/RS232 book says older format used different voltage. Logical 0 had range from -3 to -12 volts. Logical 1 had range +3 to +12 volts. Newer standard uses 0 = 0v, 1 = 5V. All usb-serial adapters use new standard. Could it be the case why all of them are not working. A good man makes a converter for me to old standard. Important question - can I damage the Tiny ADS adapter if it will receive -12v for 0 and +12v for 1?

I noticed there is a Service Reset located on the board inside the 20-pin connector. Is it accessable from the outside? Or only when the shell is opened?



March 13, 2018, 4:58 p.m.

There is no access. You would have to open the shell to use it. It would be much easier to just use a jumper wire, and I'd recommend doing that instead.

Same problem as Maxi Berger

I ordered this product and got an E-Mail with a tracking number. When I track the parcel it says it's on its way to Ararat, Virginia which has the same ZIP as Brignano Gera d'Adda, Italy where I live. While I ordered i gave my complete adress including the country (through paypal payment). How to solve the problem.


Jan. 10, 2018, 5:01 p.m.

Sorry for the confusion. There won't be any problems or delays with the delivery of the shipment. Please refer to the answer to Maxi. Again I'm very sorry USPS doesn't have a decent website for tracking. They updated the website last year and it's had this bug ever since. It's like my whole country assumes that this is the only country in existence. It's very frustrating and I apologize on behalf of us all.

Thank you very much for the info, i will wait the package!!

benemoeiusis right. No problems except for the German customs authorities. Bad luck for me but the 12€ extra were completely worth it. See my other reply

Is there no other possibility to concact somebody?

I ordered this product last week and got an E-Mail with a tracking number today. When I track the parcel it says it's on its way to Tucson, Arizona which has the same ZIP as Ismaning, Germany where I live. While I ordered i gave my complete adress including the country. Is there any possibility to get my parcel in the next time?

thanks very much


Jan. 10, 2018, 4:55 p.m.

Sorry I didn't notice this earlier but I think I had already replied to you by email. I trust you've received the shipment already. The only error is that the USPS tracking website has a bug that detects your postal code as a valid US one and assumes the package is destined for a US address. It doesn't affect the delivery of the package in any way. I'm really sorry my country's postal system has a shit website.

Maxi Berger

Jan. 11, 2018, 10:27 p.m.

Yeah ich got the package already thank you!
It was not tackable for a long time but one day it just was at home. Delivery mail came a week or so after


Oct. 17, 2017, 3:06 a.m.

Hello, I'm very interested in your product.

But I have some questions:
1/ Compatible with E36 M3 1992 3.0 EU ?
2/ Any software or drivers included?

Thank you very much.

Compatible with 325 TDS 97'?? Thanks


Aug. 28, 2017, 11 a.m.

Hi ordered this over the weekend haven't had any conformation of the order, was surprised during the checkout process not asked for delivery address? But you took the money


Jan. 10, 2018, 4:52 p.m.

Paypal provides the shipping address unless you override it. The tracking number is sent automatically by email when it ships.


July 17, 2017, 8:46 a.m.

Hi, can you confirm me the shipping cost to Spain, postal code 41120? Thanks!

Need tracking #


July 5, 2017, 10:37 p.m.

All orders get a tracking number, although not all countries' postal systems use them.


July 3, 2017, 10:47 a.m.

How long will it take to ship to Latvia ?
Are you shipping from USA ?


July 5, 2017, 2:11 p.m.

Yes everything ships from USA. I don't know what the transit time to Latvia is but maybe you can google to find out. Most countries take between 2 weeks and 2 months but obviously that's a big window and not very helpful to you. I've only shipped a few packages to Latvia and I never learned when they arrived.

i tried to order this Tiny ADS Interface inside 20 pin connector but payment was rejected by Paypal because you are listed as a "non profit organization" and Paypal in my country in Singapore cannot pay you due to categorization of this. Is there any other way to pay you?

Thank you.


March 8, 2016, 3:48 p.m.

Do you provide inpa soft?
If not, how to get it?

When i try to check out with paypal it doesn't calculate shipping what should I do?


Oct. 2, 2015, 1:19 p.m.

Don't worry. It will. Paypal doesn't make it obvious but the shipping will be calculated and added some time before checkout is complete. If somehow it doesn't then I guess you get free shipping. ;)

I'm sorry for the confusion. I'd do something about it but of course it's quite out of my control. It's been this way for a long time.

I just confirmed and purchase the product can you add alittle note to the product package from outside to ease delivery process in my country?


Aug. 8, 2015, 7:32 a.m.

Are this compatible with GT1/DIS?


Aug. 10, 2015, 11:48 a.m.

Yes, all ADS interfaces are intended for use with GT1/DIS and INPA.


Aug. 14, 2015, 11:37 p.m.

my order status is still pending since 11/8/15

order id#1251


Aug. 16, 2015, 9:29 p.m.

Yes you're quite right. I usually try to avoid marking an order as shipped until the package has actually been collected. I packaged your order over the weekend and it will be collected on Monday. I've marked it shipped just now so you should receive the tracking number shortly. I'm sorry if there's been any confusion.


Jan. 23, 2015, 12:18 a.m.

i'm searching the driver for this interface. Where can i find it?
Thank you.


Jan. 23, 2015, 8:45 a.m.

A driver is only required by INPA/EDIABAS and it's included on the INPA install disc.


June 4, 2014, 10:44 a.m.

Is there any chance to run bmwhat with this?
Thank you very much


June 4, 2014, 8:42 p.m.

I think it could be made to work, but not out of the box. You'd surely be better off with a different interface if you have a choice.

Assuming you didn't have a choice:

It looks like bmwhat uses a standard USB K-line OBD adapter. Tiny ADS is an ADS-only interface, but (if I recall correctly) any ADS interface becomes an OBD interface if you short together pins 15 and 20. If you then attach a USB-RS232 adapter, you'll have a makeshift USB K-line OBD adapter.

It should work in a pinch, but USB K-line OBD adapters are very cheap so it's likely not worth the trouble otherwise.


June 4, 2014, 4:08 p.m.

also I would like to know if it is compatible with Progman 32


June 4, 2014, 8:42 p.m.

I haven't used progman, but I believe so. It's just an ordinary ADS interface so if progman works with BMW's original ADS interface then it works with this one too.


June 5, 2014, 5:13 a.m.

Thank you a lot for everything
When I click to buy and choose the ports show me a price but when I click to pay it only shows me the price without ports..


June 5, 2014, 2:47 p.m.

Sorry, I don't think I understand. I'm not sure what you mean by 'ports'.


June 5, 2014, 4:23 p.m.

Sorry I meant shipping cost but I think will bought on eBay because there gives me the full price the item + shipping price


June 5, 2014, 4:35 p.m.

Oh, ok. I think I know what you mean.

When you're taken to Paypal's website to log in, the shipping cost disappears. I hate that, but that's just the way they do it.

Don't worry - the shipping cost will reappear once you have logged in to Paypal and are brought back to this site to complete the transaction. You will see the shipping cost before you pay.

Of course, you're welcome to use eBay instead if that's what you prefer, although unfortunately the price there ends up higher. It turns out that eBay is very expensive and frustrating to deal with, but I'll save that rant for another time and place.

I still have received nothing! controlling 03/05/14
What to do?


May 26, 2014, 10:51 p.m.

If you'd like to email me your order number, I'll check on it to make sure nothing looks wrong. You can just reply to the order confirmation email as this will contain the necessary information. I have multiple orders from 2014-05-03 that are still in transit so I'm not sure which is yours, though they do all appear normal.

Rarely, international shipments do get lost, but it's too soon to worry about that yet. Usually the best first advice is to call your customs office and make sure they aren't holding it, as this happens more often than anyone wants.


May 30, 2013, 9:44 a.m.

excellent work, wonderfull item, good quality solders and connector. Just received mine and in the process of getting it set up. Just make sure you have a real serial port!!
