From some brochure about their capabilities, it would seem that they have an iso enter in the qs profile. Why not use that? Especially if you still plan on continuing to use qs for some of the keys.

Maybe this is an alps only board? Though I don't see the point of the 'pcb-mount' -pin holes if that is the case.

But a single BNC is not enough unless you are into 1-wire stuff! You need at least a power input as well. BTW, as long as you use the pins in the mini-DP connector wisely, you won't end up frying anything even if it ends up being connected to something it's not designed to connect to. Okay, let me k...

The 10000 cycles is for the receptacle. The cable side is always designed to break first, as replacing cables costs next to nothing anyway.

Also the basic sata is usually given a guaranteed lifetime of around 50 reconnects. For user accessible connections I would suggest e-sata instead.

DE-15 is robust, but depending on the size of the keyboard you are building it might not be a valid option.

The number of usable pins is a bit lower unless you are into making your own cables. The number of usable pins is even less if you would like it to be reversible as well.

micro dsub connectors and sockets are mighty expensive, and very nice :D Consumer electronics components are probably the best for this kind of use, as they can withstand a multitude of detach-reattach cycles and are relatively cheap due to a high volume of use.

How many attach/detach cycles do you need it to last? 12 pins is a bit much, have you thought about using an io expander or something similar?

yes, and for that you don't even need a usb 3 mcu, as the power delivery negotiation is sort of separate. A 70 cent chip like tusb320 from TI is enough for that.

For usb 1.1 and 2.0 there is a separate communications channel, meaning that even if a usb 3 controller can implement a backwards compatible HID, it will just run on the old protocol without any of the improved features. There are some examples of this in cypress usb 3.0 sample library.

I haven't been able to find any HID examples that would use USB 3+, so I just assumed that it might require custom drivers. I guess we will see as razer must eventually create a 100 W LED monster keyboard with 'turbo interrupts (tm)'.

Ah, yes, the interrupt like protocol. I would really like to see how the entire thing would work. I guess a custom driver plus some kind of a virtual HID to get the operating system to work with it. I'm not sure if going past the 1 ms latency is really worth it, considering that the operating system...

What benefits do you see from using USB 3 protocol for your keyboard? The power transfer does not require you to use USB 3 protocol for the keyboard communication, at least for USB Type C.

It seems that you are correct on this. I thought that the kinetis SDK would allow for a 'battery charging' device to be developed regardless of the MCU used, but it seems that that specific service is not allowed for MKL2X devices. The USB2.0 battery charging service would have allowed for 1,5A curr...
