Support for Choc v2

[matru]

Any plans for a version with choc v2? I've been using both the choc v1 and mx versions, but there are some new choc v2 switches that are quite interesting and would've love to get them for the souffle.

As I understand it, these switches use the same real estate (15x15mm, plus use standard MX switches) so they will use the MX separation (19x19mm iirc). I am currently finishing a move (just moved to Spain) and will take a few days to set up my environment where i can update the PCBs.

Congratulations! Where from?

Choc V2 use MX spacing, but there are a few other differences.

Compared to Choc v1 they are missing two plastic legs/pins on the bottom housing, so they are a 3 pin instead of a 5 pin switch by default. The center plastic pin is also thicker on the Choc v2. Everything else is the same.

	Choc v1	Choc v2
Pins	5-pin (2 metal + 3 plastic)	3-pin (2 metal + 1 plastic)
Center Pin	Thinner	Thicker (I think 4.8 mm)
Spacing	Choc (low-profile spacing)	MX-compatible spacing

Choc v1

Choc v2

Since Choc v2 has less pins, and it's has a thicker center plastic pin compared to Choc v1, you could technically design a board that supports both choc v1 and choc v2 very easily. Just switch the spacing to MX instead of Choc on a Choc v1 board, and widen the center pin a bit. Now the board is compatible with both Choc v1 and Choc v2! The only caveat is that people would have spacing between the board if they use Choc v1 keycaps without modifying them to be a bit larger.

It's exactly what the Ferris Sweep has on their "High" variant, and I think it's the optimal design (scroll to the bottom), but you could also of course find the spacings and implementation in the gerbers.

There is the Flake keyboard, which actually allows for hotswap on all types of swtiches, including Choc v1 and Choc v2, but also MX, they can have both Kailh MX and Choc hotswap sockets soldered as demonstrated here, but it's a much more complicated design.

Of course the Choc v2 benefits a lot from having a top plate for stability since it only has 3 pins, so gerbers for a top plate on a choc v2 version would be great.
