What is the connector on this ? Is it something exclusive to pycom, or an industry standard used by ESP32s and others ?

Hi Donald
The small end of the cable might have a little psh on connector to suit whatever is on the Pico device. The end with the nut panel mount looks like SMA or similar. The info and pics are delightfully vague aren’t they?

I might add here the larger connector (that the antenna screws onto) should be mounted in the centre of a ground plane which should be a little over half wavelength in diameter for best results.
That way the results are more predictable.

Hey Donald,

I had to grab this off the shelf to check, but it’s definitely a Female U.FL SMT connector. It’s used across a wide range of the industry.

A helpful diagram I have in my notes:

The other end, as Bob said, is Female SMA connector.

Hi Jane
I realise hat pic is only something ou have in your notes. The SMA end does not look like the actual connector used. That is assuming the pic in your component description is correct.
It would not hurt too much if Core published close ups of these 2 connectors in their product description. Would save a lot of queries.

Hi Bob,

There might be a misunderstanding.

The picture I posted is of the U.FL connectors. It’s for clearly distinguishing between male and female U.FL connectors. No SMA ends at all in this photo. I was posting it in case it helps someone else in the future.

I do agree that the lack of clear photos of the connectors and a lack of specs on the web page is a problem. I’ll go ahead and update the page with some more information and clearer photos.

Also, a small correction, SMA end is actually a RP SMA Female connector. My mistake.

Hi Jane
Yes, a bil tmore comprehensive info would be a help. Not to me personally at this time but for others in the future

The “RP” i think signifies reverse pin (socket). SMA is available with either pin or socket (M or F) in the fixed or cable connector. One is designated "Reverse SMA. I forget which way around this is now.
