Talk:Teensy++ 2.0

NANDway

• Solder 3.3V regulator on Teensy (and cut 5V pad)
• Flash the HEX to the Teensy
• Solder all control + I/O wires + Ground
• Crash it (it will beep and blink red led), press power button to have a solid red led
• Make sure to use the right nand id for nandway.py
• Dump it

Notes

<judges> nand powered with 3.3v by atx doesnt work
<judges> nand powered by teensy requires huge delays to work kind of reliable
<judges> teensy powered by usb, nand powered by external psu with 2v works like a charm..
<judges> thats why nandway worked for me.. it's slow. my own version is almost twice as fast and only worked on my first nand. second one always gave errors..
<judges> powered by teensy seems to be right on the edge of whats still working
<judges> but only with 10ms delays between page reads..
<judges> current power draw is 1.13amps at 2v
