Where can I find the info, which type the plug for the 12V connector (J23) for the LimeRFE is? As there are plugs with different diameters available, the right dimension is important!
I do not own the hardware, so I can only say what I would do if it was me:
I’d goto http://github.com
Search for “LimeRFE”
Click on the hardware, … ponder … normally I’d expect to see a BOM (Bill of Materials) in one of the folders, but there is none there.
Oh well time for plan B, click on hardware/1v31/PDF/LimeRFE_1v31_Schematic.pdf.pdf and on page 3 of the Schematic it shows connector J23 with the outer shell indicated as being ground (pin2) and the inside pin of the connector as being +12 volts (pin1) and the part used was a RAPC712X. And a quick search in a random search engine on that part number gives the following:
|Industry Recognized Mating Diameter||2.50mm ID (0.098"), 5.50mm OD (0.217")|
|Actual Diameter||0.098" (2.50mm ID), 0.248" (6.30mm OD)|
|Number of Positions/Contacts||2 Conductors, 3 Contacts|
Exact dimensions for the “jack” are at https://www.switchcraft.com/Drawings/rapc712x_cd.pdf
So you would need a “plug” connector with a 2.5 mm (0.098") inner barrel diameter (for the +12 volts) and a 5.50mm (0.217") outer barrel diameter (for ground).
Thank you mzs. This ist exactly the info I wanted.
