I've been keeping an eye on this board. It looks very promising? You mention that the board is QMK-based but also has a very long battery life. From what I've heard, QMK boards don't really have a long battery life due to the way polling is done (but I'm not sure). How do you manage to do this?
Also, if this board supports split spacebar as well as 2u shift, it may very well be my next keyboard!
Actually, it's not about the QMK itself, it's about tunning an AVR MCU(most of the custom keyboard use this kind of chips), by shutting down unnecessary module, we can almost cut down half of the power consumes. I wrote a custom main loop and matrix scan function for further power saving. Yang, who made YD60BLE created this precedent, his TMK based firmware consumes just 1.7ma standing by, I'm following his path and trying to keep up.
BTW, Splited spacebar and 2u shift are dropped for sure on G60, Sorry for that. But I would like to release this PCB separated later, it could be a much compatible version. and... Are we just forget this is a compatible case for any GH60-like PCB?
