Hi,
I’m designing a board that I’ll be soldering an RF-24G board onto. I just wanted to make sure that the pins are 1.25mm spaced in both dimensions before I commit to my board layout. I understand that the spacing between adjacent pins in a row is 1.25mm, but I wasn’t sure about the spacing between the two rows. In the pictures in the datasheets, it looks like this spacing is slightly larger, but maybe the image is scaled.
Thanks!
I captured the photo of the pins in the datasheet and measured the spacing in Paintshop… if the aspect ratio of the image hasn’t been altered, then it seems like the rows are 1.45mm apart. I guess I can design my board to accomodate a range of spacing (1.25-1.45mm) by using larger drill holes, if no one responds.
Sorry for all the posts! :oops: This question wasn’t really worth asking anyway… I just looked at the numbers, and I can accomodate a range of row spacings from 1.25mm to 1.45mm with very reasonably-sized drill holes. I’ll be ordering my RF-24G’s shortly. Thanks!
Wait a minute… the header shown in the datasheet (RF-24G_datasheet.pdf) is soldered on to one side of the board on page 4, where the pinout is given, but is shown on the other side of the board on page 5, where dimensions are given.
Does the RF-24G board come with these headers soldered on? And if so, which side of the board are they on? I’d rather not design my board one way, then find out the headers are on the other side and the pinout is mirrored.
I’m confused. We’ve posted pictures of the RF-24G units showing the header is mounted to the back side. The silkscreen indicator is on this side as well. I’m not sure how you could mistake which pin is which. Creating a correct footprint is tricky however.

Thanks for getting back to me. It’s good to know that the pinout is the same as shown in the pinout diagram.
I’m not sure how you can be confused by what I wrote, as I cited specific pages in a particular datasheet. Compare the “Bottom View” image on page 5 of “RF-24G_datasheet.pdf” with the image you’ve got posted on your site. Notice that the positions of the mounting hole and header have been swapped? I had thought I was looking at the top side of an unpopulated board, but I guess someone accidently mirrored the image. Anyway, good to know that yours is the definitive version.
Sorry if I came off like a jerk there. I was just a little frustrated because I’d made an Eagle package for the part by referencing the mirrored image, since that’s the dimensioned drawing. I guess Laipac made the datasheet, not you, so I shouldn’t have vented to you. Now that I’ve got the right info, it’s an easy fix.
Hey now…I’m the real jerk around here. And there aint room for 2.
In spite of that, I’m glad you’ve got it figured out.
