Ok, I have another board routing, will let that finish & get these ordered.

Thanx, I appreciate it very much !!!!!   :)   8)

Upon arrival, I'll deploy it immediately over my MEGA which only has very few improvised (Mexican style, hahaha) connections at present. I will be using almost all of the screw pin terminals except for Rx & Tx eventually.

Please let me know when you're ready.   :)

Boards are ordered.
Get past 100mm & price jumps.
Bare boards will be $7.30 mailed to US locations.

Folks, I've had several requests for a kit with screw terminals and header pins.
I'm up to at least 16 kits so far.
I don't mind doing a group buy for the connectors, prices drop with quantity.

I've worked up the best combination of Phoenix screw terminals from mouser.
For the life of me I can't figure out what they call stackable headers like these:

Any ideas?
Thanks

Alright, I am going with 2 sources.
Mouser for the 3.5mm screw terminals.  They don't carry stackable headers in 1x8 and 1x10 0.1" configuration.
Dipmicro for the stackable headers. They don't carry 3.5mm screw terminals.

Okay, here's what I'v worked out.

I originally said $7.30 for a bare board. That was incorrect and was based on 10-lot boards from itead, the larger sizes are 5-lots.
So a bareboard will be $13.60.
I've priced up material for5 kits, since I'm getting 5 boards.
Total with shipping for itead, mouser, dipmicro, USPS to you, and paypal's 2.9% + $0.39/transaction fee comes out to $41.25.

First 5 paypal payments to cardinalflyer @ comcast dot net get a card.
bibre asked for the first one, a university teacher asked for 1, so it's really the next 3.

If there's enough interest, I'll order more.
Cards will be here in 2 weeks or so.

$41.25 per board is for a kit - board, ten stackable headers, 21 screw terminals.
Sizes selected to yield lowest cost per pin or terminal.

$13.60 for just a board.

Price is material cost, supplier shipping, and my mailing costs.
Passing on the benefit of bulk buy on the parts.

$41.25 is a very good price. Do your math.

I paid for a similar screw shield (the Wingshield) for the Ardiono UNO $16 bucks. But the MEGA 2560 has at least 3.5 times more pins than the UNO. And that's 3.5 times more terminals and headers!

So I guess, if you need it, go for it. It's a fair price, for a lot of hardware.   ;)

On the other hand, just buy the bare bones board.   :)

My brain got hung up on the "materials for 5 kits" comment, and registered that as $41.25 for all 5 boards.

CrossRoads

No, that's $41.25/kit.

Yes.  I'll admit to my brain shutting down it's higher functions while I was reading that.

Boards are in - 4 left.

Bibre - I didn't order material yet. Hopefully the pics will inspire folks to commit - otherwise I'm only ordering connectors for 2 boards tomorrow and anyone else can pay for their own shipping on parts from wherever.

WOW! Grrrreat looking boards. Congratulations.   :smiley-surprise:

Ok Robert, I'm not in any hurry, no problem at all.   :)

The quality of your board looks excellent and its price is fantastic, inexpensive.

Sorry to see that you haven't had a reasonable demand response for these kits as they are also very affordable and will save you a lot of time and money vs looking elsewhere.

Everybody owning a MEGA2560, who is really going to put it to work, not only experimenting, should buy one of these. It's a must have for deploying!   8)
