Hi, thanks for the responses!

I like that connector - I'm gonna order a couple of them to play around with. I hadn't considered something like that, and I always love an unexpected option or suggestion. Even if I don't use them, they'd be nice to have around.

Good point - more specifics are always great. I need a variety of pin counts for different modules. currently, I need a 24 pin, 12 pin, and 40 pin connector. I could use multiple pins for higher current, though, so those numbers can be higher (I.E. using 6 pins for a power connector.) I plan on using them for both power and signals, and the fastest signal on the board is an I2C bus, so either 100k or 400k b/s. As far as power requirements go, the servos are the MG90S style, so the entire leg draws under 3 amps (2.1 amps + safety margin) during complete stall. I'm doubling up on the pins, however, so each pin only needs to handle 1.5 amps.
Actually, what I want is the copper tracks on the board which go into a female receptacle. I'm looking for something akin to a PCI slot, where I can design cards that simply have the tracks on them. At least that's what I'm currently considering my frontrunner. However, I always like alternatives, so if you've got a cool two part system, I'd love to see it!
For weight, I'm actually still under my max weight by a decent amount, and the hexapod can handle an additional ~.5kg on its back without too many problems. Let me know if there's any other specs you'd like to know, I'd be happy to provide them!

I've definitely considered the headers, as well! I'd be sold if I could find some right angle headers that mount on both sides of the board, so that the board rests in between the rows. I've attached a photo, for reference. This, however, seems a bit prone to wear and tear, and it's definitely a non-standard usage. One other question, what is the mating cycle count on headers? I haven't found any conclusive figures, and the amounts that I've read on forums and reddit range wildly.

I've actually been using the Micro:Bit system as a reference for some of my research! I was thinking that their connectors might be more durable because the cards are designed for kids to use. Those parallax boards look almost exactly like I want the modules to look. Is that set of connectors going to be on parallax.com? I'm assuming that they're going to be releasing them in a few weeks, which is why I can't find any of the connectors on the site currently. That's great to know though, and I'll keep a close eye on them.
