Description

• Based on Atmel ATMEGA32U2:
  • 32kB of memory...twice the code space of the commonly available AT90USB162
  • Full code compatibility with AT90USB162 (no need to recompile hex)
  • on-board bootloader means the device can be reprogrammed at anytime without a separate programmer.
• Design isn't stripped down to bare-minimum components (which causes long-term stability issues)
• Two separate buttons means the USB stick can be reset and sent into programming mode independently
• Buttons are full-size--no fiddling around with tiny little switches
• Small board size (about 1" x 1.5")
• 0.1"-spaced breakout on panel edge means easy access to the IC pins and inter-operability with almost all breadboards and stripboards
• Open source!  Schematics and documentation linked above
• Excellent support!
