I'd suggest taking a look at AstroDev's He-100 offering, which uses the
PC-104 card connector.
Page 7 has the pinout, Page 20 has placement
I would hesitate to use a board quite as large as that though, as it is
highly optimized for the CubeSatKit, making use in other chassis
difficult. I would suggest a slightly smaller board in line with
Boeing's CS82 board factor. Slide 6 from this year's CubeSat Developer's
Conference @ Cal Poly
Are either of these the golden standard? Not exactly, but it is the
closest thing I've seen to one. Ease of integration and flexibility are
the key to getting your transponder flown.
