Hi friends, I'm trying to make a clone of the teensy 2.0 based on pjrc's schematics, however I'm not an engineer, so I need to review a pair of things about the schematics with someone who knows more than me, can anyone help please? Xboxman ?

hi, i have the exact same question someone else had before, for the teensy 1.0 schematics, do you have to use an exact schottky 54c diode? is there any other alternative? i'm having a hard time finding one around here.

So I got mine built and working. However, the LED doesn't seem to be doing anything.
Teensy 1.0 clone (AT90USB162, flashed via FLIP). LED is good, connections are good. Chip works, can play backups no problem. Just the darn LED isn't flashing. Its not a BIG deal, but I'd like it to;

I remember reading that teensy 1.0 led has polarity inverted, could it be the problem?

I wired as shown in the schematic. No go.
Then I saw what you mentioned and rewired it to
But still no go. Anyone have a revised schematic yet? Or am I the only one with that issue? Or is it unique to Teensy bootloader code thats not available on stock AT90USB162 flashed using FLIP?

hi newbie here, just a question.. is there flashing the AT90USBKEY-psgroove.hex into teensy board(as schematic shown) will become the psjailbreak (alike the product currently market sale).
do i have to use the development/evaluation kit to perform the flashing the teensy board?

Yeah its all right. I'm an EE, while it is possible for me to do something small like that, i checked it over n over.
It also doesn't work on the actual 2 Teensy 2.0 boards I got. Flashed the posted HEX file, and while the hack works..the LED didn't actually do anything. Not a huge deal, the main part works and thats what matters.
