I'm happy to see more Indian projects on Geekhack but there's some issues here.
1) This is not an IC, IC's are specifically made for feedback.There is no IC form linked.
2) It looks like a copy of the BN006, which is still available for $40 on their website. I'd probably make some design & layout changes(maybe add some 2u support,since choc stabilizers exist).
3) Post better pics of the proto w/ different colours. I know it's just black and white but still it would be nice to see. Show some pics with the Rubber back/Silicone back.
4) What material is the plate made out of? Is it an integrated plate?
5) "Low profile switches makes it more reliable, much faster and gives the premium feel to any user.It gives a level up gaming experience with an amazing keypress sound" This is just marketing bs and not needed.
6) How are you planning to sell these? Vendors/self fulfillment?
7) Consider VIAL support.
I'd take these suggestions into account and ask for more feedback on IMKC discord. GLWIC
