Great work, I'm currently working on a project that requires 2 Dues interconnected on a PCB. This would be a huge space saver for us. We'd definitely be interested in a low cost solution. Will keep track of your progress!

P - if you come up with schematics to connect to my RMII pinout, I promise I will make the shield ;-)


No problem Val. I kept running DM9161 and KSZ8051MNL PHY chips with DUE some months ago without problems but the sketches and libraries still raw. I needed ten pins from the DUE but I believe MMI pins (MDC/MDIO) are not necessary (I need to verify that). Anyway, please, confirm to me the broken out EMAC pins of your DUE-based board as follows:

PIN NAME                              DUE PIN
-EREFCK: Reference clock pin-----------113 ETX_CLK
-ECRSDV: Carrier Sense/Data Valid------119 ERX_DV
-ERX0: bit Receive Data----------------120 ERXD0
-ERX1: bit Receive Data----------------121 ERXD1
-ERXER: Receive Error------------------122 ERX_ER
-ETXEN: Transmit Enable----------------114 ETX_EN
-ETX0: bit Transmit Data---------------115 ETXD0
-ETX1: bit Transmit Data---------------118 ETXD1

Thanks,

Yes, I have these exact pins broken out. I looked at the BOM for Micrel-based shield and I think we could offer a ETH MicroShield at $15-20 pricing point

Man, that would be a good deal considering that some Micrel distributors sell the KSZ8051MNL small eval board for more than US$100.

FYI we were talked out of 2mm pitch pins. So 0.1" pitch it is.

JWScotSat

Do you have any timescale on when you might know the pricing?

valerun

I am relatively certain it's going to be below $25 for the MicroDue board

dkrenzel

Are there by chance schematics available yet for the MicroDue board?

Thanks for your interest!

Not yet - board is still in testing.

We should have some good updates in the next 3-4 weeks. Production is ready to go as soon as we get it through testing.

Hello Val!
I hope everything is going well with your tests of the small-footprint Due. I am eager to work with it and specially interested in the CAN bus functionality. Regards,


Palliser

Hello Val! ANy news on the Small-footprint Due? Thanks.

paperslammer

Nice work - this is something I am interested in as well.

bobcousins

I would be interested in this too, but it seems to have disappeared down a black hole.

I might have a go at designing something similar.

I made a start :)

ETA: Just for the archives my version of "MicroDue" morphed into "CoreSam3x" and I started a new thread http://forum.arduino.cc/index.php?topic=275705.0

Hi Friends,

I did an Arduino Due compatible design based on ATSAM3X8E but somehow USB interface is not working.
I have my schematics and the detailed issue posted here:

http://forum.arduino.cc/index.php?topic=328843.msg2269583#msg2269583

Since you guys have experience of making a smaller Arduino Due board, can you please help figure out what might be the issue with my design?

Thanks
