PapaC Posted April 13 Share Posted April 13 Looking to make some shorter cables that go between the receiver and radiolink PRM-01 battery telemetrics model, connecting to the Gnd, SDA SCL, and 5v What is this type of connector call, it is smaller than a servo connector, four pins is almost the same width as a 3 pin servo connector.

Geoff S Posted April 13 Share Posted April 13 Never seen that one. Are you sure the pin/socket spacing isn't 0.1" ( as servo/receiver connectors are) Quote Link to comment Share on other sites More sharing options...
Allan Bennett Posted April 13 Share Posted April 13 (edited) I'm pretty sure it must be 0.1" pin spacing (2.54mm) if it's to go onto the 4 header pins on the PRM-01. I get sockets like that from RadioSpares (RS) in almost any number of pins in 1 or 2 rows, like this one. You need the crimp pins to go with them like these. Look for "Crimp housings" and pins on other sites and you'll possibly get them cheaper/easier. Edited April 13 by Allan Bennett Quote Link to comment Share on other sites More sharing options...
PapaC Posted April 13 Author Share Posted April 13 Definitely not 2.54mm spacing, 2.54mm is the same size as used on raspberry pi header pins, this is smaller than that, the servo connector is the one on top for comparison. Putting a ruler next to the pins they are about 2mm centres. Quote Link to comment Share on other sites More sharing options...
Phil Green Posted April 13 Share Posted April 13 2mm spaced header sockets are almost as common as 2.54mm outside R/C, not at all unusual, we use them for in-circuit programming headers :) There are many types, Harwin, TE etc all do 2mm plugs & sockets Quote Link to comment Share on other sites More sharing options...

All the DiL logic ICs I used to use had 0.1" (2.54mm) pin spacing as well as the analogue operational amplifiers. (still have loads I can't persuade myself to throw away 🙂 ) Of course, that was 30 years ago. Things change and I commend the sensible move to proper metric units.

PapaC Posted April 14 Author Share Posted April 14 Found some 2.0mm connectors on AliE....... , they are not going to break the bank so taken a punt on them being the correct size Quote Link to comment Share on other sites More sharing options...
Phil Green Posted April 14 Share Posted April 14 You realise thats just the shell, the actual crimp connectors are a separate item? 🙂 Quote Link to comment Share on other sites More sharing options...
