I am looking for a simple breakout board design for a SH1.0 4p SMD connector to be soldered to. Something similar to this in a compact as possible form factor. https://www.pololu.com/product/4772 Just looking for a gerber or other compatible file that can be sent off to one of the PCB manufacturers, or even better if there is a source for ready made ones. ![[Image: QnRmtXQl.jpg]](https://i.imgur.com/QnRmtXQl.jpg) ![[-]](https://intofpv.com/images/collapse.png) • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 What you are asking for is pretty simple. If you watch a tutorial for Kicad or EasyEDA, you should be able to do it yourself. I would recommend sourcing the SMD connector first, so you have it on hand to reference to for dimensions. • Posts: 1,734 Threads: 60 Likes Received: 1,010 in 731 posts Likes Given: 96 Joined: Jan 2023 Reputation: 52 I had a look at easyEDA, but not knowing the intricacies of PCB layout rules I figured for someone with experience it would take less than 5 minutes. I did not find the library for the SMD SH1.0 connector but also imagine there must be that for easy drop in. Sounds like you have done your own PCBs? Maybe you can send a simple rough draft design? • Posts: 4,073 Threads: 75 Likes Received: 2,548 in 1,858 posts Likes Given: 3,949 Joined: May 2021 Reputation: 121 If this is so that you can plug in a walksnail vtx and have it be removable, rather than a breakout board or soldering wires onto an smd male jack like I think I recall seeing you do in another thread… I’d suggest using a through hole vertical mount header instead. It’ll be lighter than a breakout board, and would have pins sticking straight out the back that you can easily solder to and heat shrink. Like this: https://www.digikey.com/en/products/deta...gLoWPD_BwE You’ll have to double check if that is actually the right size for what you need. If it’s not, it’ll at least give you an idea of what to look for. Dangerous operations.

I wish I could get the smell of burnt electronics out of my nose. • Posts: 1,734 Threads: 60 Likes Received: 1,010 in 731 posts Likes Given: 96 Joined: Jan 2023 Reputation: 52 You got it, but that connector you show has a 2.5mm pitch pins, the SH1.0 is only 1.0mm. The ones I solder to are actually the vertical ones, but the part of the leg that extends beyond the plug needs to be measured in microns, I doubt I could get a wire soldered onto it securely, so clip them off and go for the longer side that is flush against the plug. They are made for SMD so have SMD sized legs, there are two larger unconnected tabs on the side which I believe are the main points for securing the plug to the board, otherwise they would be too easily lifted. You can see both types here ![[Image: Jf9wDcNl.png]](https://i.imgur.com/Jf9wDcNl.png) • Posts: 4,073 Threads: 75 Likes Received: 2,548 in 1,858 posts Likes Given: 3,949 Joined: May 2021 Reputation: 121 Gotcha. Well, I tried. If you manage to design one or find someone to design one for you, I might find it useful as well. Last time I made a pcb it was the old way with permanent marker and acid.  Dangerous operations.

I guess there are ones using cnc to etch out the traces too. I guess just soldering the SMD plug to one of these copper plated PCBs and scratching out 5 lines to create the 4 pads would work too... with some precision scratching. • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 (15-Jun-2023, 04:12 PM)mstc Wrote: I had a look at easyEDA, but not knowing the intricacies of PCB layout rules I figured for someone with experience it would take less than 5 minutes.

It has been a while since I designed a PCB board. I will try to help when I get a chance. No promises. • Posts: 377 Threads: 28 Likes Received: 165 in 106 posts Likes Given: 185 Joined: Feb 2022 Reputation: 6 If voodoo614 doesn't do it I can possibly help. However, I can't find any library for those connectors so you would have to give me design details with all dimensions made in something like Paint. If you do the research, draw it and provide all dimension details, I can then "convert" your drawing into a PCB (gerber files). • Posts: 1,734 Threads: 60 Likes Received: 1,010 in 731 posts Likes Given: 96 Joined: Jan 2023 Reputation: 52 Thanks for everyone's help. I found the plug with the datasheet/cad files here. Would that work or you need something else for the gerber? https://jlcpcb.com/partdetail/XkbConnect...SN/C400341 It opens in EasyEDA, but I don't really know what I am doing, but was just thinking a simple compact breakout layout something like this. Don't know if that spacing would be too tight. If JLPCB assembly service is not that expensive, I would have them solder on the plug too. ![[Image: y23rX34l.png]](https://i.imgur.com/y23rX34l.png) • Posts: 377 Threads: 28 Likes Received: 165 in 106 posts Likes Given: 185 Joined: Feb 2022 Reputation: 6 17-Jun-2023, 12:12 AM (This post was last modified: 17-Jun-2023, 12:13 AM by Mike C.) I used old Eagle software, with my limited knowledge on generic PCB design I have never made it on to other software. Tried KiCad once and got overwhelmed so I stuck with good old Eagle, so I can't use those cad files. The datasheet is enough to create the footprint though. I'll see what I can do. What is the diameter you want for the through holes you solder your wires to? • Posts: 1,734 Threads: 60 Likes Received: 1,010 in 731 posts Likes Given: 96 Joined: Jan 2023 Reputation: 52 Hmm... I guess large enough to thread through 24awg wire so 0.8mm? diameter or maybe there is some standard via size to choose from? I am actually using 30awg wire now, probably inadvertently adding some voltage sag. Thanks again for your help. • Posts: 12,099 Threads: 125 Likes Received: 3,739 in 2,836 posts Likes Given: 99 Joined: Feb 2017 Reputation: 388 17-Jun-2023, 05:20 AM (This post was last modified: 17-Jun-2023, 05:20 AM by voodoo614.)

KiCAD would have been the better choice to start with but it wasn't around when I was doing this stuff so I am confined to Eagle. • Posts: 1,734 Threads: 60 Likes Received: 1,010 in 731 posts Likes Given: 96 Joined: Jan 2023 Reputation: 52 Wow that looks super!! Is it possible to go even more compact, for the width I was hoping just wide enough to clear the connector. Also the plug-in side of the connector to come up closer to the edge of the board, no need for the JST_SH silkscreen. I was planning to just shrink wrap the whole board after soldering and use it as a wire connector.
If this board works out well, maybe even a second version with a built in v-reg and pit switch... • |
