I would like to have instructions how to convert my KiCad project the way it can be assembled with your service.

Information about the stackup for a four-layer PCB.
I would be nice to have a stackup for every PCB thickness seeedstudio provides. This makes impedance based routing possible.

more components in Open Parts Library, 555, zeners, comparators, power FETs, voltage references, voltage regulators (78XXX)

Create an OPL lib for Kicad

Offer PCB size 65x56 for Raspberry Pi Hat.
ATM I have to order 100x100 Board to get 65x56 Raspi Hat.

would you please describe it in a clear way that how can I purchase some ordinary components from Iran?

I wish that in the OPL parts, you can find a place also for an optoisolator like the PC817. This is a good component when we need to make a strong separation between different supplies. Especially for microcontroller!

Change the Gerber files

A simple, wired outlet is something I find myself making all the time (left side of photo), but I'd rather buy something smaller/safer/nicer than keep making them :)

The [more expensive] wireless product can have the same functionality of a "normal" rf (or ir) controlled outlet, but the remote control would also have a grove socket. If it's necessary to have 2 buttons/pins in order to control such a device (like the a/b buttons in the photo), you can use both yellow and white lines (unorthodox for non-I2C grove modules, but I don't see any reason why not).

I wish to have in your OPL list the posibility to use the well common MAX485. When I develop boards with Modbus communication feature, I always need to use this components.
Thanks

Show all the steps using some example design right through to ordering
and show the result.

The BNO055 is a neat orientation sensor which reduces the hassle of 3D orientation programming a lot. I would love to see this sensor (which has an I2C output) paired up with a Grove connector!

The FPC service is really great! Adding the option of:

- 3+ layers
- Smaller copper weights (0.25 oz, etc)
- Increased max outline dimensions (beyond 10cm x 10cm)
- Stack-up information (for controlled impedance designs)

in the future would be very much appreciated!

Can't get shipping information

I'm trying to check out as a guest, but the form won't let me continue without entering account details (password) to create an account.
If that's compulsory, don't offer guest checkout, as that clearly doesn't exist now.

I had known it would take almost a week to send my order i would have ordered elsewhere.

I use to login with facebook and order several orders. But I cannot do it with new website

New products or new versions of products, Grove Temp sensor V1.2, could not find it. Many bad links. Kit products with new version of hardware but wiki goes to old version of the product. Grove Starter Kit for Arduino V3 has some in it. New products or versions of products in the store going to old versions on wiki. I think the store and the wiki could use a good going over and clean up.
