KeyDuino, Arduino NFC (PN532+ATMEGA 32U4) by MrStein
-
@Lokki I asked Pierre to send me a prototype board so I will look at it and create a video in English :)
-
Awesome, I'll be looking forward to hearing how it goes @johnyma22!
-
Wow the nano one is incredible.
How can I make/get one? -
I start a prototype today so I can't say when the final design will be done... (soon I hope ! )
I send you the board tomorrow @johnyma22 , there are some mistakes with the V1; pn532 became hot, baudrate fixed at 15200, uart configuration,... (you will see) ;)
@Lokki Oh you're right for the USB, it will be really cool if I can do that! :D
-
@MrStein, it would be absolutely awesome if it was able to be plugged in upside down. All they appear to have done is sunk the contacts down a whisker on both sides so that it doesn't short circuit on the shield. Seems like a pretty simple solution to the age old usb problem of never plugging in properly the first two times!
So will you be doing this one in association with your work, or looking at a kickstarter?
-
I am currently an apprentice so I would like to make a kickstarter with my work for that project (as final project study). :)
-
Well, that's awesome. Just let us know when you're ready and I'll throw my wallet at the computer screen.

First view of the boards:
Now I have to make a proper bom before started the implantation of the components :) -
I really do love that 'keyduino', @MrStein.
Very nice. -
Here is a vidya of the larger board in action :)

Keyduino will be assembling soon, first test on december :)
3d view from sketchup:
-
Construction done, now I wait for them from china :) (the maker of the board say he had a problem for load the bootloader on the atmega 32u4, I expect it's not a big problem)
-
Awesome I'm excited to try it out!
-
I don't receive the board yet but I start some shield (for NFC ring or just NFC card)
A NFC playing card game, with an LCD. Each card have a nfc tag.
A mux 1 -> 4 for more antenna (that can provide a lot of projects, gaming, multi acces control,...)
A protoboard
A low cost relay shield (Car starter, switch control,...)
If you have any idea of shield/project to do tell me ! :)
-
I can't wait to get my hand on the relay board too! That's awesome dude, keep up the great work :)
-
MrStein if you have any board you don't use I'd be happy to try one or two.
I can pay for it if you want.
Contact me please. -
Hi,
I only have 1 arduino nfc uno and 2 keyduino with some problem.
I received the keyduino yesterday, with the polarised capacitor in the wrong way (I resolder them). But the chip are both locked when they tried to put the leonardo bootloader. (device signature = 0xFFFFFF)
I'm not really good in fuse setting, maybe some of them can held me?french part //
@Nairod785
pour l'instant j'en suis encore à la phase de prototype, je pense qu'il y a du chemin avant d'arriver à un truc totalement terminé.
J'avais envoyé un prototype à john, je peux toujours te mettre en contact avec les producteurs qu'il relance un prototype mais en faire un seul sur demande ça risque de couter cher (30-40$). c'est toi qui vois mais je pense que c'est mieux d'attendre ;)
Bonne fêtes ;) -
Win !
One works, seconde one have some problem with the bootloader 0x000000for the fuse now.
There is some little modfication to do for the harware (add interrupt pin from the pn532 -> "low" power mode) but that look like good :)Basic password logger:
-
Excellent !
@MrStein Ok je vois, je vais attendre encore un peu alors :)
Tiens nous au courant, c'est vraiment super ce que tu fais!
Bonne année :D
