The Kona328 contains a trace that can be cut to disable
the auto-reset. The pads on either side of the trace can be
soldered together to re-enable it. It’s labeled “RESET-EN”.
You may also be able to disable the auto-reset by connecting
a 110 ohm resistor from 5V to the reset line.
USB Overcurrent Protection
The Kona328 has a resettable polyfuse that protects your
computer’s USB ports from shorts and overcurrent. Although
most computers provide their own internal protection, the fuse
provides an extra layer of protection. If more than 500 mA is
applied to the USB port, the fuse will automatically break the
connection until the short or overload is removed.
Physical Characteristics
The maximum length and width of the Kona328 PCB are 2.7
and 2.1 inches respectively, with the USB connector and power
jack extending beyond the former dimension. Four screw holes
allow the board to be attached to a surface or case. Note that
the distance between digital pins 7 and 8 is 160 mil (0.16"),
not an even multiple of the 100 mil spacing of the other pins.
