For now, the motor start with a defined time, there are no check if it's really launch or not.
If you want, you can connect a optocoupler on the pin n°3 of the header "EXT" and connect the optocoupler to the ODB2 pin 7 ;)

RE: Where to get it?
Hey @Laszlo, we already launch a new production of 100 boards, in fact there are 96 boards lefts ;)
Currently when you buy a pack on elecrow, it's the same design than the KS version but there are some little change:
- reading distance a little bit improved thanks to a new matching circuit
- all pack come now with a big deported antenna, that can read 2016 nfc ring only
I don't know if I relaunch another production after this stock, as the sales decreases quickly.
But I currently I work on 2 designs:
- the keyduino nano (same than the normal one but smaller)
- ozOne, a NFC reader with wifi, LEDs and LIPO charger
Keep me in touch if you're interested :)
[TUTO] NFC car doors control with KeyDuino
Here is a tutorial that allow you to control your car doors by a NFC communication;

RE: [WIP] NFC car starter by MrStein
It's a good question, I currently make a tutorial for the doors opener and use a push button to start/stop the KeyDuino.
For the NFC starter, I use the temporary light (that allow 30s of supply to scan the ring/tag).
I don't know how long you can use a battery if you use like 150mA, but I think it's a bad idea to "always powered" something in your car ;)
How, just for your information, if you have any question/ rem related to keyduino; please sen them on the keyduino forum, so me and my friend can answer to your question :)
RE: Where to get it?
For now, the small antenna's orders are closed but some of them will be selled by ELECROW with the keyduino soon.
I take the decision to add some free antenna in these pack :
But if you didn't order one of them, and your really want a deported antenna, please contact me with your KS account by message.
Also note that you don't need any deported antenna to read the NFC ring as there is an integred antenna. And that the large antenna work really fine with the 2016 ring.
RE: Congrats! (& questions)
Thank you! :D
We will make a update for the antenna, you will be able to buy them on EBAY ;)
First estimation: small one for 3€ and big one for 4€ (with 10cm cable). Keep you in touch.
For the temperature, really great question... we have made some stress test; voltage input,... but not temperature... A quick look with the datasheet of the 2 most sensitive components:
PN532: -35° to 85°
ATMEGA32u4: -35° to 85°
So if you don't leave in the north pole or in hell, it will be okay :)
I don't know if the temparature have an impact on the reading distance... I will search or spend some time playing with the freezer ;)
