This may work… I cannot guarantee exact placement of board and rectangle, ect. You might have to consult with the fab house to make sure they can v-cut as necessary. I’m sure you can make due this way

Multiple PCB on 1 gerber file
Fifteen years ago, PCB houses happily sectioned boards if I sent them a CAD file of it. I don’t know what they do ‘today’ because I’ve made my own boards since (via CNC). However, the approach is the same and I now do it in Fritzing.
Using Inkscape (or any drawing app) there is no need to go through the hoops of making layers. When ‘Loading’ the file into Fritzing, you can ignore the messages - the board loads fine and exports as normal.
A picture being “worth a thousand words”, you can glean from the image what’s going on. Fritzing file attached. They provide the concept… Also attached is the SVG with extension changed to fzz (for uploading).
Many ways to section it - this is simply one way…

Hum-900-prc part
Either module will work fine in fritzing. BUT if used on a 2-layer board only, I would call it a BETA unit used for designs and in-house reference only. NOT used in a final product to customers/friends ect. YOU cannot properly perform the PCB design and layer stack requirements to be FCC complaint.(start page 84) NOW I’m no pro, but can clearly see the Figure 91 requires this for an end version of your product to be FCC complaint.
As you can see in Figure 92, layup is easily possible inside fritzing. You just need to start on page 84 to understand the facts of this FCC compliance requirement. Anyhow, compliance is a whole other deal, and not covered here.
BUT according to Figure 91, you can meet Top and mid-layer1 requirements with fritzing. YOU are just missing Dielectric 2, mid-layer 2, Dielectric 3, mid-layer3. Peter is correct, fritzing cannot do that. BUT you can however have the board-house building your board, add these addition layers to your PCB, for your product to supposedly be compliant. Regardless, a easy workaround if you only need to layup on the top-side. Peters part will work a treat for anyone needing to use this module. Just note and read the .PDF and understand the FCC compliance guidelines.
Parts here should be labeled EXPERIMENTAL, for BETA purposes only… Just to cover peter’s parts actual requirements. Which cannot be met using fritzing.

Looking for an STM32 Blue Pill Part
Thanks, used that.
Does not have copper pads for the bottom layer.
Tried unziping fzpf and editing the svg.pcb.xxx.svg to the same pattern as a different part.
reziped
imported without error,
reloaded my project
Still no copper on the bottom layer.
Did I screw up the edit ?
Do I need to do something to update the part in a project ?

You just put copper1 inside a group called copper0.

Hum-900-prc part
The pdf says
"The castellation connection for the antenna on the pre-certified version allows the use of embedded antennas as well as removes the cost of a cable assembly for the U.FL connector. However, the PCB design and layer stack must follow one of the reference designs for the certification on the HUM-900-PRC-CAS to be valid. Figure 91 "
This is for the castellation version only not for the UFL
It also clarifies and says
"Note: The PCB design and layer stack for the HUM-900-PRC-CAS must follow these reference designs for the pre-certification to be valid.
The HUM-900-PRC-UFL and the HUM-900-PRC-CAS must use one of the antennas in Figure 108 in order for the certification to be valid.
The HUM-900-PRC has not been tested and requires full compliance testing in the end product as it will go to market.
All modules require unintentional radiator compliance testing in the end product as it will go to market."
Again the pcb layer stack reference is for the CAS version only! the UFL just has to use one of the listed antennas in Fig 108 for the certification to be valid.
At least this is how I understand what is being stated I have not heard back from the supplier to confirm and I will be out of town for the next week I hope that I will hear from them by then.
Thanks

In those copper1 contains copper0.
That does not work either.

I can make it double sided but I can’t get rid of the layer warning and that annoying empty VBAT pad, plus there is a lot of stuff in silk that is not needed, so I think we need Vanepp.

What did you do to make it DS ?
I am trying to get better at this ?
I only care a little about the warnings - if it will route both sides.

Go to XML Editor in INK.
Select g:557
Then Object Ungroup, Ungroup.
Select copper1, go to id, change to copper0 and set.
Still on copper0 go Object Group and name that copper1.
Extras are Ungroup g:511 twice, so silk is the only one left.
Go into silk group and delete - red box in XML toolbar - all but path6 and g:505.
Save as plain svg and load back into FZ PCB Part Edit.

Does an Arduino Uno Mega Shield SD Card ICSP SPI Exists Already?
Hi Peter,
This is not working in my scenario for some reason. Can you see what is wrong?
I ordered this part - https://www.mouser.com/ProductDetail/595-SN74AHC125NE4
Here is my schematic -
The pins are the bottom represent the Arduino UNO pinouts… Top left is CS, Pin 10. Bottom is 3.3 V. Just noticed I am missing the ground symbol but everything is grounded.
UPDATE: I have separated the VCC input on the chip (now goes to +5) and sd card reader (stays at 3,3).
Before, both were being powered from the 3.3.
The result is no change; it still doesn’t work.

Small Transformer 14x19x15h
Preliminary brightness testing only, no accuracy testing.
With old LED timing light circuit :-
1 - 4 off 5mm LEDs
2 - 8 off 5mm LEDs - resistor value wasn’t reduced for larger current draw, so light intensity could be improved
3 - 8 off 10mm LEDs - resistor value wasn’t reduced for larger current draw, so light intensity could be improved
4 - Peter’s(Vanepp) new improved LED timing light circuit using 8 off 5mm LEDs . The circuit filters stray after-triggers and increases light by delaying LED switch off. and that produces a longer “block shape” mark. To use this circuit accurately you must only use the leading edge of the timing mark.
I stuffed up with the COB because it was 30V, and that made it barely turn on even without a resistor.

Creating a wire
Hello friends,
would there be someone nice here, to make me a simple electric wire?
I did not find that kind of thing to download.
I wish I could change its length, color and thickness (fine wire) .
Many tank’s

Ability to use components allocated in the schematic view for the breadboard or streapboard ,

Thank you
getting that right was tedious.
Aparently loading and saving in parts editor after editing with inkscape is critical

Creating a wire
In which view?
BB makes it’s own wires, and in SCH and PCB you link a wire from your start point make a temporary connection to any part. Then you add a bendpoint and Delete wire up to bendpoint, and that makes a floating end.

I think it’s possible.
You can save it as a new part, pull the SCH view svg from it and load it back into BB view.

Mark groundfill seed pins as connected
When a connection is marked as a groundfill seed, and there are no wires connected to it, that connection is represented as unconnected.
↧
Create a VCC Seed option
Groundfilling is very useful.
But it should be possible to VCC fill the opposite layer of the board, and it should be possible to mark a pin as VCC Seeded.
