The right Arduino Mega cable connectors

Other Hardware General Electronics

Hi,

I'm heaving a hard time figuring out which housings and terminals to use to connect my wires directly to the female Mini-PV connectors on my Arduino Mega boards.

I want to crimp my own cables with 8x1 and 18x2 male connectors, but everything that I find is about female connectors. Even the manufacturer Amphenol wasn't able to point me to the correct part numbers for my case.

So what I need is:

  • 8x1 male terminal housing (65039-029LF ?!)
  • 18x2 male terminal housing (65043-028LF ?!)
  • Male terminal (?!)

Kind regards,
Raymond

Just use a double row pin header with long pins on both sides as an adapter.

If you can find it. Or these:

Do you know what part number that is?

No, it's an Aliexpress link.

I'm using AliExpress stuff for prototyping, but for my end product I'm using official parts only... What is the intended way to connect a whole bunch of cables at once, instead of one-by-one?!

Arduino did not take that into account.

There a 18x2 box headers that you can place on a print and next take it from there Possibly with other connectors); instead of box headers, you can use double row pins. Just a search on RS: https://za.rs-online.com/web/c/connectors/pcb-connectors-wire-housings/pcb-headers/?pn=1&searchTerm=pcb+headers&applied-dimensions=4294869557,4294882462,4294882463&rpp=100

No idea what offical parts are. Visit you favorite local shop to find what you need.

Personally, if I wanted to go professional, I would go for a Mega Pro (do a search) and design a PCB around that.

Apart from @sterretje's advice to use a better designed module, the answer is to design and build your own "shield" PCB to plug securely into the Mega 2560.

That is the point - the UNO or Mega 2560 format is designed for a "shield" to fit, not individual connections. The Nano and such are more practical.

I had another try with the Amphenol service desk, and now they were able to point me to the correct parts, so for future reference:

  • Amphenol FCI 75967 (Male terminals)
  • Amphenol FCI 65039 (Single row headers)
  • Amphenol FCI 65043 (Double row headers)
