Are you still finding 60% casing?

Here is the spec sheet.
As far as I understand.
- UVCC, UGND , D+, D- is for usb pin
- Port B C D E F is the available pin, and port F seems to be analog.

No idea for the rest of the pin, and I have no idea if the atmega32u alone will work, or requires other component too. Firmware should be similar with teensy firmware since its the same controller.
*
The rest are just biasing Pins.
Just see what others are doing and straight copy. Like XTAL/RESET etc.

Not sure whether you are using ADC in your firmware. My feel is that you don't use it. In that case, just bias it so that ADC is disabled. That means
AVCC is connected to VCC.
AREF should be left to be floating, or high , or low. Not sure..need to see what others are doing.
XTAL1 & XTAL2 to the crystal
RESET to an external reset circuit, preferably a push button.

Easier to just get Taobao PCB fabs to make for you.
Just supply the necesary files.

Printing your own PCB isn't hard especially with UV. Beats the ferric chloride method.
But good luck drilling those holes. You would have to deal with a few drill bit sizes, and alignment might be an issue. It's not your everyday undergraduate electronics project.

Just pay the money and get the China people to do for you.

@faridr
What's your problem with the spec sheet again?
Reading spec sheet I do that a lot. Writing firmwares...maybe not.
*
yeah I've to admit the drilling ain't gonna be hard. but well let's see what can we do from here first. and i'll check up the faps in taobao and see what's their price. Also, in your opinion do you think we can achieve something like QFR-I with teensy 3.1? since it has more on board memory to store stuff. the hard part is obviously trying to control the leds individually. some more no EE background is a pain in the ass.

also, bro set is live now. 90usd owai for full full full set.

Got EE background also no use.
These kind of things, if you don't do it, you don't know.

You can ask many EE, they gonna stare blank if you ask them how to control Leds individually. Myself included.

I'm not sure whether you can do a QFR-I. My advice is to start small. Or you can use Proteus to simulate.

sad.gif seems like controlling it individually is a very deep topic. and yeah, going to start small. first, gonna try handwiring 87key phantom layout and use easy avr firmware. Then, going to design the PCB based on the matrices and hopefully we can name it LYN PEH keyboard as suggested by dadudeneverabides then only head to more advanced (whole backlit) LED stuff.

Aaah, got it, reset will be useful. Can the atmega32u take 5v power from usb or need resistor to drive the power down? Searching for atmega32u kit with solder hole, hopefully there is one so I can test it out. SMD is impossible for me to work on

Should be that way. Teensy boards take USB power directly and I don't see any resistors on the board.

So feiton is having a sale on the older CM Storm quickfire pro and trigger mechanical keyboards

https://www.facebook.com/feitoncomputer/pho...?type=1&theater

Is it worth getting them? and if yes is it worth spending extra on the Trigger MX red? I like it because it has a full back lit and extra macros.

Trigger is ok. Quickfire is not.

I've just look into teensy and komar gh60 diagram on atmega32u, its actually far more complicated. Requires few resistor, capacitor and 16mhz clock to drive the atmega. So better to stick with teensy sad.gif
