For PCB questions.
1,LDN have faster CPU. We use STM32F103. 72M frequency. More faster and Expandable. Key scan frequency:500hz(of course we can 1000hz but no need). We use another programme method and believe it can be more powerful. Control software is easy to learn to use. And we will use more advanced STM controllor to make it better.
2,Alough we wont open sourse,but we will open API.
3,We will have a video to show the light mode. It can be customized by our software.Instructions will released when GB open.
4,We will keep updating LDN and fix the bug.If you have any question using our PCB you can PM me here or send an email, We will answer all the questions regrading our product.
5,We dont think other PCB is bad, we just want to create a new PCB and work on it.
6,Instead of standing on the shoulders of giants, we want to be giants.
P.S we will do both B.87 and A.87 Size.
For Switch questions.
1,It's not just change of colour,it also smooth.
2,Since we started this project really early so we didnt use transparent bottom. We may do it later to fit our RGB Pcb.
