Teensy++ 2 for terminal F-style layout?

[QuincyJones]

Would a Teensy++ 2 have enough pins for a terminal F layout with 2 rows of F keys above and 2x5 down the side? I've counted a matrix of 30 (5 main rows + 2 rows of F keys + 2 side cols + 14 main cols + 3 arrow cols + 4 numpad cols) and a generous 4 more for leds, so 34 in total which the teensy++ 2 seems to be able to handle ( https://www.pjrc.com/store/teensypp.html )



All those extra keys would come in handy, though I'd certainly be wanting to add in windows keys! Total n00b when it comes to keyboard making but reading around here has got me very interested! I assume Soarer's firmware would suffice?

As is, you can't use a Teensy to drive a capacitive matrix like you would a typical SPST (or similar) based one. Soarer's converter however doesn't need to do that - it simply adapts the output of the existing controller on the board, takes the power + clock/data pins, and outputs USB. So, even a non++ teensy2 suffices for that.

Ah, I should have specified, I mean for a new custom keyboard build, not to modify an existing terminal keyboard!

Good stuff! So that confirms the teensy++ will be able to handle it! Lots of ideas. Only downside is I don't fancy paying 122+ cherry switches!
