NRF24L01-PA-LNA in components library wrong?
-
Hi, I just found the KiCAD components library, just after I made my first design, so I already had a footprint made.
Since I assumed that the footprints in the library are better controlled (I don't even have the device yet) I exchanged mine and found out that the two footprints are mirrored ... in mine, when looking at the module from the top, antenna on top, VCC is left. In the MySensors library, it is right.
I made my footprint according to the image in the description of this auction I googled: http://www.ebay.com/itm/2Pcs-2-4G-NRF24L01-PA-LNA-Wireless-Module-Ceramic-Antenna-1-27mm-2-2-3-6V-/271968125413
From the position of the antenna, I would say that VCC left ist the correct way, but I am surprised that the MySensors library is wrong ... -
Also the case of the footprint in the library.

I think I found the problem. For some reason KiCAD puts the symbol of my version into he schematic, despite the fact that I am clearly choosing it from the MySensors lib. We chose different pin numbering. Apparently, KiCAD cannot deal with parts of the same name in different libraries.

@LastSamurai Originally I designed it but since then it has been added to the official mysensors-kicad repo https://github.com/mysensors-kicad
Both regular SMD and PA+LNA SMD footprints and 3d shapes are verified to be working, I already used them quite a lot. -
@emc2 Thanks but I was looking for the (non smd) trough hole PA+LNA version. The one you linked is only smd, right?
-
Ah yes right.
For non-smd they both have the same pinout, so you should be able to design it using the regular footprint, and then just plug a PA+LNA module in the header. -
I did, I just needed the dimensions of the module for the antenna placement ;) Just measured mine though
