Ah. I wasn't thinking "dimension" as frame sizes.  Thanks.
As a hobbyist, I am used to taping a mylar stencil onto a board.
I'm having a little trouble imaging how to ensure aligment of a 10cm x 10cm (or smaller) board inside the very much larger frame area.

For manufacture little PCBAs, it is very easy to align the board to the stencil, just like the picture

For assembling small batch of the PCBAs, we will panelizing the boards and using a clip machine to align the boards to the stencil and fix them. We are writing a blog about how the PCB assembly works for small batch of the PCBs.

Another good news is our PCB services support same boards panelizing, only need add little money, and you will get double or more boards, especial suit for the boards with 5*10cm dimension, for example, you only need to pay $31.9, and got 20 separated 5*10cm boards or 10 10*10cm panelized boards which with V-groove. For the boards which with V-groove, you don't need to cut them buy yourself any more.

What does "provide you five dimension options" mean?  Website does not provide any more info.

Hello CrossRoads,

sorry for may unclear description! The following are the information for the dimensions:
Frame DimensionEffective Dimension
37.0cm x 47.0cm   19.0cm x 29.0cm
42.0cm x 52.0cm    24.0cm x 34.0cm
45.0cm x 55.0cm    27.0cm x 37.0cm
58.4cm x 58.4cm   40.0cm x 40.0cm
55.0cm x 65.0cm   37.0cm x 47.0cm

Different dimension has different price, for the dimension of 37.0cm x 47.0cm, it only needs $20, this dimension can meet most needs.  Thank you.

Very nice.   Pretty much what I am looking for to control one stepper motor without wasting more pins on unused motor capability.  Where can I buy one?

One request is that you include top header blocks to keep the unused I/O pins available.  It would be a pain to have to solder up a prototype shield board to go between the main board and the motor shield when a simple connector for a couple pins would do for a sensor or output.

Thanks.

Hi,

Thanks for your kindly suggestion. Consider to use the connector than have both female and male header in the next batch...

Besides, you can go to here to buy the Motor shield directly.

Best Regards

Hi all,

W5200 Ethernet Shield in Elecrow is available now!



The controller of this Ethernet Shield is W5200. it is twice the buffer size of W5100 and support for up to eight simultaneous TCP/UDP connections. There is an onboard micro-SD card slot, which can be used to store files for serving over the network. Thanks to a lowered RJ45 pot, you can flexibly add most shields on top of this Ethernet Shield.

Features:
  • Standard Shield that Arduino, Mega, Crowduino Compatible
  • High speed Ethernet controller W5200 with internal 32K buffer
  • With Micro SD card for storing large amounts of data
  • Connection with Arduino on SPI port
  • Support up to eight simultaneous TCP/UDP connections
  • Lowered RJ45 Ethernet jack
  • Long wire-wrap headers extend through the shield

9  Community / Products and Services / Motor Shield with current measurement on: February 23, 2013, 02:42:05 am
Hi all,

Today I want to introduce our new product - Motor Shield to you.



The Motor Shield is a platform for robotics and mechanical applications based on L298N. The biggest characteristic of this Motor Shield is it can measure the driver current via the two high power cement resistor(the two big white resistors in the picture).

It can be used to drive 2 DC motor or a 4-wire stepper. When controlling 2 DC motor, Only 4 control pins were needed, which makes this shield easier to control, and saves the control pins of controller. The Drive current can be up to 2A  output, also, the enlarged heat sink can help the chip work in good condition. with the current measurement, it can makes your control system more smart.



For more details please visit Elecrow Motor Shield.

Hi everyone,

I glad to introduce one interesting Relay Shield to you.

It has little difference with other relay shield,  4 white buttons are particular noticeable. Yes, these four buttons allow you to control 4 relays manually, give a special use feeling, it is very siut for newbie of electronic.

Besides, its headers are used length headers, so it is extendible, you can plug other shield to it.

Hi all,
Today I happy to introduce our GPRS/GSM Shield to you.


This Arduino compatible Shield allows you to send and receive data through the GSM Network, it is really ideal for you to harness the power of GSM network to your projects!
The Shield allows you to achieve this via any of the three methods:
1. Short Message Service
2. Audio
3. GPRS Service

With this shield, it will be possible for you to make much more attractive projects such as:

1.  Your own Arduino phone to call your friends.
2.  SMS controlled relays. With which, it would be easy make your home smart.
3.  With a GPS Shield, a “tracker” to send location to somewhere. Such as a Trackers for the elderly
4.  Wireless monitor, send the temperature, humidity, illumination intensity and so on to your phone or a website.

We did some improvement on it like using 2-in-1 headset jack, for more please visit Elecrow - GPRS/GSM Shield For Arduino

Shipping is free, correct?
Will I be getting a 15cmx15cm PCB, or will you be cutting the PCB to correct size and outline (with edge connector, etc.)?
Yes, for order over $50, we offer the free Registered Air mail shipping. The dimension is base on your design dimension, for example, if your board is 106.05 x 110.36mm, you will get a 106.05 x 110.36mm board.

Your site is confusing!  

Tell me how much these would cost please.

106.05 x 110.36 PCB
double-sided
ENIG surface finish
Gold Fingers (routed, card edge x 15 x 2 sides)
Sorry for cause inconvenience, we will fix the mistake as soon as possible!
For your case, it need you to select 15cm * 15cm dimension($72.9), ENIG surface finish(+$19), total price is $72.9 + $19 = $91.9 for 5pcs. If you need 10pcs, it will need extra $18, you can order it in here. Thank you.

I dont understand, in the front page http://www.elecrow.com/services-c-73/
It says...
Code:
2 Layer 10 * 10cm Max - 10pcs (Color Free)
This service provides quick and high quality PCB fabrication experience for worldwide hobbyists. In this service, you...
$9.90

... more info

However, this is FALSE ! When you choose a 10x10 board it adds +14$.

maybe I am not understanding something but definately if I read 10x10 board for 9.90 I dont expect to select this board and get a higher price
Sorry for cause this confusing, please give us a little time, we will fix this problem ASAP!
15  Community / Products and Services / Re: Cheap Fusion PCB Service(Color Free) !! on: January 09, 2013, 11:03:26 pm
I see that your trying, but I dont see how text on a computer saying 5x5 price = 9.90 is any harder than text on a computer saying10x10, price = 9.90, which is flat out false

here
http://www.elecrow.com/services-c-73/

you have 3 simple html links, change the prices to reflect what they actually are, and dont have the dumb drop down box in ordering if someone clicks a specific size if thats too complicated, cilck a 10x10 board? fine only deal with the 10x10 size and dont give the option for other sizes (and add a 4th for 5x5)

not that hard
smiley-roll-sweat Actually, our company was spend lot of time to discussed this problem.. Finally get this best format(just our Wishful thinking.. smiley-red) to show the services. Thank you for your suggestion! we will reconsider this problem.
