Razer Orbweaver Chroma MCU mod

<< < (4/4)

Just registered to say this is awesome!  I'd been thinking about how best to make a keypad that was independant from Razer's software for the last couple of months.  No other vendor seems to offer the amount of control on the thumb that Razer's products do, so I was just starting to look at the possiblity of modding them with a QMK MCU.

I wonder if a custom PCB could be designed in the same footprint as the original Razer MCU board to try and eliminate the breakout board and breadboard.  It should be possible to make a carrier for the Elite-Pi RP2040 then move the FCC and JST connector over to the new PCB making it a little more plug and play... (you could of course go the whole hog and design the whole RP2040 onto a custom PCB but that would be a much bigger design task...)

How is the pad in day to day use?  Am I right in understanding that there is no reprogramming of the keys/rgb without recompiling the firmware?

RE - custom PCB - something similar to this project

With QMK, calls to rgb matrix effects are built in. So it's actually a convenient way to manage key-layer specific color maps.  But it also provides a programming environment for custom animations (in this case based on the key-layer specific color maps).

could you drop the code in the github?
