Arduino Nano Gateway for Vera - PCB link

[rosskinard]

Here is the link to the Gateway PCB I created, had fabricated and tested.

http://oshpark.com/shared_projects/qPdmZWG3

Keep in mind that OSH Park charges by the board size, and you get 3 of the boards. This one costs $14.65 for 3 copies.

Since few people need more than one it might make sense for users to pool together and order them as a group. That does mean one person will be responsible for ordering/paying and will have to ship the boards to the others.

Vodden and SirMeili have called dibs on the 2 spare ones from my prototype order.

Please give feedback.

Parts needed:
R1 and R3 - 220 ohm resistor (for RED and GREEN LEDs)
R2 - 470 ohm resistor (for BLUE LED)
R4 - 10K ohm resistor (INCLUDE button pull resistor)
C1 - 4.7uF electrolytic capacitor (4mm diameter - 2mm lead spacing)
Button - https://www.sparkfun.com/products/97
2x4-pin header socket - http://www.ebay.com/itm/10PCS-2x4-Pin-8P-2-54mm-Double-Row-Female-Straight-Header-Pitch-Socket-Pin-Strip-/310727244114

For the Nano socket...I used 2 of the 16-pin header sockets and cut one off with a Dremel to make a 15-pin strip.

Let me know if you have any questions.

Here is the Gateway assembled:

Fantastic!

[Dvbit]

Thanks. Fantastic.
I am looking for somebody wanting to share the order with me.
I will order from Italy (Rome) so ideally other Italians would be better (shipping costs wise) even though all Europeans are welcome.

Please pm me.

Great looking work.

It appears this is the USB version. Does anyone know of a PCB for the Ethernet version?

[clippermiami]

Ross, i've sent you a ENC28J60 Ethernet device to work with. In looking at it however if not already you should be aware that there are two versions of this thing, the
"narrow" one I sent you (about the width of the Ethernet connector) and a slightly wider one. The pinout is the same just wider so I thought i'd mention that in case you were not aware as you begin playing around with the PCB layout to accommodate the Ethernet adapter.

[clippermiami]

It seems like it would be practical to design a general purpose sensor board with a number of population options

1. Populate with parts for external power
2. Populate with parts for battery power
3. I/O connections using screw terminals to allow connection various devices, power and ground. For example a screw terminal strip connected to the unused I/O pins, a ganged Vcc screw strip, a ganged Gnd Screw strip.

The base board could carry a Nano (for simplicity ) and a radio. The terminal strips would allow attachment of a variety of I/O devices, light, temp, humidity, etc.So we'd end up with a single PCB that could serve as Gateway or remote sensor, power options, connection options, etc.

@clippermiami Ross, just wondering if the Post Office delivered the Ethernet adapter?

I've received my Serial Gateway PCBs today and tomorrow I'll put one together. Hopefully I'll have better luck with your PCB version than I've had with the scramble-wire one I've been trying to get working for two weeks now

[clippermiami]

@clippermiami Ross, how is the Ethernet Gateway PCB coming?

[rosskinard]

@clippermiami Boards arrived...waiting on some sockets and a few other components to arrive so I can assemble it.

[clippermiami]

@rosskinard good news, looking forward to it

[rosskinard]

@clippermiami Still waiting...gotta love ePacket Delivery from China. Never can tell when you'll get something.

I'm watching/waiting too

We should do a custom case for it using 3D printing.

[clippermiami]

@BulldogLowell That would be good. I'll buy one, you volunteering? My 3D printer is in the shop for service, it ran out of 3D

I don't have any 3D either, but I have a good hookup from the last project!

I will just need to get a PCB. When you have it working, I'll buy one (or two) and then I'll do the housing.

[clippermiami]

@BulldogLowell I'm looking forward to it as well and plan to buy a board when it is available. Right now I'm using Ross's excellent serial gateway but I really want to get it on my LAN instead.

[clippermiami]

@rosskinard Yes, it arrives when it gets there

[Omemanti]

Looks really great!,
Are there any Dutch people who would like to order some?

[daulagari]

@mark-van-winden : Yes, interested and living in Holland.

Price for three boards is reasonable and shipping, if you are using first-class mail, should also be not too expensive.

[daulagari]

Placed an order an no additional shipping costs!

@mark-van-winden: Let me contact you, I like to two of them but if you still want one...

[hugob]

Also living in Holland. Looks like all three are gone, but if one is left over, I am interested

[daulagari]

$14.65 is €10.92 and you can pay with PayPal. No custom charges because it is below €22.

Seems like (not sure!) panelization would be done tomorrow.

[daulagari]

$14.95 is about €11, no shipping or custom costs, so also if you just need one board...

Got just an email saying:

Your Nano Gateway V2 copy boards are on the July 31st 2 layer prototype panel.
Once we fill up the panel with other orders it will be sent off to the fabricator.

[tbully]

I'm in for one or two if there's an opportunity.

[samppa]

I would also take a few for Ethernet Gateway. (The USB is so unreliable an annoying during reboots when the serial port forgets the rate on vera3..)

[RJ_Make]

What's going on with these?

[TroyF]

So I ordered a batch of these from OSHPark and they arrived a couple weeks ago. I've put one together but I'm running into a bit of a problem. Let me start by saying it's almost certainly me. I'm sure the boards and the design are fine. I'm pretty confident the Nano and the radio are fine too because they were working fine on a breadboard.

So when I plug everything together on the PCB the TX and RX and Power lights on the Nano are on solid and stay that way. The middle LED on the PCB gives a brief flash and that's it, nothing else is happening. If I take the Nano out from the board it seems to boot up normally.

So I've looked at my solder job and while not great I don't see any shorts, but I don't quite understand why the TX and RX lights stay solid when connected. If I connect the Nano to my laptop when plugged into the board it doesn't recognize a COM port.

Now I should admit that I did not put to capacitor for the radio onto the board, I just shorted the holes. I wanted to try it first without the cap. because I hadn't needed it on the breadboard. My brain tells me this shouldn't be causing a problem, but maybe it is?

Any suggestions that anyone would have for me to check would be awesome.

Thanks!

[TroyF]

Ok so.... things not to do:

1. Don't short the holes for the capacitor.

When I thought about this some more I realize it didn't make any sense to do that. I clipped the short and presto the Nano booted properly, no solid TX RX. So I cleaned the holes and put the capacitor in just for kicks and I think everything is working now.

A big thanks to Ross for putting the PCB together it's awesome!
