Hi all, great to be part of this community, I wish you all well.

I need help to get fritzing part MAX485 CD4069 RS-485 to TTL converter.

Here is the reference: https://www.circuitstate.com/wp-content/uploads/2022/12/MAX485-CD4069-Module-Pinout-r0.1-CIRCUITSTATE-Electronics-2.png

Anyone have any source to this part? If not maybe have to create a new one.

Thank you very much.

Hi Peter,

I did tried to search on Google for the part but the part is for the MAX485 breakout board with DI DE RE RO / VCC B A GND.

The one I’m looking for have these pins: VCC TXD RXD GND / A B SC

I think I have done my best to look for it but I still haven’t found any yet.

Then you need to provide a web site with mechanical and connector data for the module that you want. The picture above isn’t much use in making a part as it has no mechanical data such as dimensions.

Sorry I got caught up with something else just now.

This is the website for the breakout board module, it has a reverse engineered schematic for the breakout board: https://www.circuitstate.com/pinouts/max485-cd4069-rs-485-module-with-auto-data-direction-control-pinout-diagram-and-pin-reference/

Below is the outside dimension of the breakout board.

Let me know if you need more information, thanks.

This is a more useful site for the necessary data:

https://www.amazon.ca/Diitao-3-3V-5-5V-Conversion-Hardware-Automatic/dp/B0B52WN1K4

specifically this image which gives the layout of the board flat suitable for importing in to Inkscape to lay out the part (the dimensions are in another image.) This is the type of information needed to make a part.

Hi Peter,

Sorry for the later response, I am out of town these couple of days.

Thank you for your kind effort. I will take note on the advise for future posts.

Hi Peter,

Are you able to update the Part to include the notches on the Pin ends, so it’s able to be surface mounted.

You are a Legend!

Thank you!

Hi Peter,

Are you able to update the design? I have tried it and it’s a bit too small. The SMD pads are barely longer than the board.

Not sure if it’s because it’s a slightly different board.

But the HW-519 is 15.5mm wide and 47.5mm long.

Thank you!

This part may do what you want. I can’t find any such board with a 47.5mm length. The usual suspects are 42.5mm like the original board. You would need to print the pcb footprint out at 1:1 scale and check it against your board before ordering boards as the pins were positioned from your image and may not be accurate.

Hi Peter,

Printed the PCB footprint out at 1:1 scale and check it, looks good.

Thank you for the quick turn around!
