I love this. 2 questions about it.

1. Will there be a way to store the wireless receiver on the board?

2. What is that component that sits just north of the resistors?

Thank you for your praise.

1. I haven't thought of it at the moment because it will fit 60% normal cases, i will also open source receiver so people can design cases for it. Also, I'm also planning for a smaller usb-c receiver.

2. That is toggle switch for on off power.

Updated answer some questions.

1. What’s the case going to be like?
* Any 60% tray mount case, aluminum case is ok because of antenna is placed above PCB.

2. 2.4ghz instead of bluetooth?
* Both, 2.4ghz from keyboard to receiver, and bluetooth from receiver to other device.

3. Will you have an UK vendor?
* I'm afraid not, direct shipping from Vietnam.

Well this is freakin rad. Is that a supercap? Those scare me...
