I am making my own pcb that combines an Arduino Uno with the Duinotech LoRa breakout board in one module instead of stacking them. I can't find a schematic for the Duinotech LoRa board but I was wondering if anyone knows how I could work around this. Thanks!

Not sure I follow.
Are you making the arduino circuit on a PCB?.
The normal way is to use headers but that is kind of stacking.

Duinotech LoRa board is not open-source as far as I know. So, I don't think you'll find the schematic.

I've made a few pcb's in my time you can get a blank sheet of board with a layer of copper on it then you can draw the circuit on with black permanent marker and the etch the board with chloride. Put the board in a ceramic or glass container copper side up, and fill the container with chloride so it covers the board, move the board about every so often to see when it's done, when it's finished. When the acid is done taking all the copper off. and has left behind the black marker ink. Take it out of the acid bath and dispose of the acid properly then when dry, use wire wool to clean off the marker ink leaving behing copper tracks and voila ready for soldering, thats how I done my boards in the past anyway!

FPGA field program gate array 64 pin you're going to etch that on a copper clad board?

I don't know what you just said, just thought I'd try help out with telling you how I etch boards it's perfect for dip chips and resistors and capacitor diode etc you do need to drill the holes though, ok i looked it up no I dont think my method would work for FPGA field program gate array 64 pin

by the way I can't see anywhere else in the thread about "FPGA field program gate array 64 pin"

I actually really like this approach what is the "toner ink" for the "toner transfer" I presume it can be put through a normal printer using photo paper and and of course the iron, and then etch using the method that I described using chloride bath?

Yeah me either but it's scary though. I have seen etched copper clad this should be put up on a wall it's a piece of art functional.

Hello,

As it sais, Toner Transfer. A laser printer is used and the toner is transfered to the PCB, using heat, like an iron at low temparature (just hot enough to melt the toner on the PCB.
Some even use a modified laminator for the toner transfer.

Hello,

No, an inkjet uses ink. A laser printer uses toner.

ok yes I see thanks for the clarification, so then any laser printer?

is there a way to build a pcb design from ltspice files?
