After 1 year, the keyduino nano is available! :D
You can found the board at elecrow for 25$ (here)
It's still a ATMEGA32u4 but I redesign the NFC antenna and add few ameliorations.
Currenlty I try some project like communication with a credit card, HCE communication, etc. If you have any cool projet to suggest with or without the NFC ring, tell me !
If your antenna + according circuit is matched at 13.56Mhz, there are no problem but I think it will be difficult to find an antenna that match with the according circuit currently on the keyduino and you will need to change some component value to improve your reading range ;)
Hi Parviz, sadly I don't sell any prototype due to legal responsability, if you only need to unlock the car by NFC, you can follow this easy step by step tutorial: http://www.instructables.com/id/NFC-Car-Door-Control/
Bye,

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 ;)
It works, you have to click on "téléchargement gratuit (vitesse NORMALE)" then wite the captcha and click on "télécharger ce fichier".
There are only the layout and not the schematics but I can upload both if you want.
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:
But I currently I work on 2 designs:
Keep me in touch if you're interested :)
Bonjour à tous, KeyDuino est disponible sur ELECROW pour 40$ (FDP out) avec une petite antenne, il n'en reste que 12 disponibles!
KeyDuino is now available on ELECROW for 40$, there are only 12 boards lefts!

Here is a tutorial that allow you to control your car doors by a NFC communication;

Lib and APK here: https://github.com/CITCEuraRFID/KeyDuino
NFC ring code : KeyDuino lib>example>relay shield
Hey Logan,
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 :)

Hey !
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 :
-DELUXE CLASSIQUE
-DELUXE NORMAL
-MASTER
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.
Bye,
Pierre
Hey!
@Laszlo yes, you can get a KeyDuino on elecrow website when all backer will be shipped :)
Keep you in touch for that!
Nop sorry :(
But it's North-of-france approved and trust me, it's really cold and wet everydays here! :p
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 ;)
One backer just cancel his pledge and it was a early bird one! if you go fast you can change your order/back this one and get a KeyDuino for 30€ :)

Ahah, thank you for the edit :p
The goal is just to showing the keyboard use of the leonardo bootloader but I'm agree, it's not a secure way is you plug it all days.
For the driver, I'm working for a new bootloader, that will name the keyduino "keyduino" instead of "leonardo". Problem is about the unsigned drivers (the way to accept a driver without signature is not the same between Win7,8 or 10). So it will be a little bit difficult..
the code:
/*********************************
You will need PN532_HSU.h & PN532.h library to use it.
***********************************/
#include < PN532_HSU.h > #include < PN532.h > #define BUZZER 15
PN532_HSU pn532hsu(Serial1);
PN532 nfc(pn532hsu);
String NFC_Key_1 = "xxxx";
String NFC_Key_2 = "xxxx";
String PASSWORD = "xxxxxxxx";
//*******************fonction lecture de tag
String fct_lecture() {
String Received;
boolean success;
uint8_t IdReceived[] = {
0, 0, 0, 0, 0, 0, 0
};
uint8_t Id_Length;
if (success = nfc.readPassiveTargetID(PN532_MIFARE_ISO14443A, & IdReceived[0], & Id_Length)) {
for (uint8_t i = 0; i < Id_Length; i++)
Received += String(IdReceived[i], HEX);
return (Received);
} else return ("NULL");
}
void setup(void) {
Serial.begin(115200);
Serial.println("Hello!");
nfc.begin();
uint32_t versiondata = nfc.getFirmwareVersion();
nfc.setPassiveActivationRetries(0xFF);
nfc.SAMConfig();
pinMode(BUZZER, OUTPUT);
}
void loop(void) {
String Received;
Received = fct_lecture();
if (Received != "NULL") {
Serial.print("NFC tag found: ");
Serial.println(Received);
if (Received == NFC_Key_1 || Received == NFC_Key_2) {
digitalWrite(BUZZER, HIGH);
delay(100);
digitalWrite(BUZZER, LOW);
Keyboard.println(PASSWORD);
delay(1000);
}
} else Serial.print(".");
}
EDIT BY JOHN, adding three ` before and after your code makes it a code block and does syntax highlighting :) Also I fixed your lazy indenting! :P
I hope too for the nano!
For the KS, 82% reached and it remain 24 days and I know that a good part is thanks to the NFC ring community, so thank you to support us ! :D
The nano will maybe available in another KS... it was too difficult to add the 2 in the same crowdfunding (estimate the number of boards principaly) so I had to choose only one.
Nano is really cool but to discover the nfc without any experience, the arduino format is better (easier to use, to plug and the compatibility with arduino shield doesn't require a adapter).
I don't know if you can add 2 times the same contribution but else yes, the super pack (2 KeyDuino+realy shield+ tags) is the only way ;)
