Arduino from Scratch Part 7 – Arduino USB Connection

The arduino has a diode to prevent wrong polarity to reach your power supply, it also have a resetable fuse (the kinda big, often green SMD part close by your USB connection on your Arduino) that should protect your USB port pretty good from its side of the cable.

The Arduino LEONARDO is an integrated USB HID Arduino board. Ideal for projects requiring the board to behave (act) as a USB human interface devices. 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.

Setting AVR Fuse Bits: How to change fuse bits of AVR

The Arduino/Genuino Uno 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.


1/6/2012 Standard Fuse PS - If you just want the same ones as used in a standard Arduino, you can find them in the boards. txt file: uno. bootloader. low_fuses=0xff uno. bootloader. high_fuses=0xde

May 2016 / Arduino Arduino pro mini @ 1MHz - 1. 8V. During my water tank project, I realized that even with 3 AAA batteries, the voltage will go below 3. 3V quite quickly : you cannot use the serial / USB link. You will need an ISP programmer. Same remark with the Arduino Uno and the Arduino Nano. Extended fuse: 0xFE / 0x06 (or 0xFF

Understanding Arduino UNO Hardware Design

When trying to upload the bootloader to my Arduino Uno board, avrdude fails (see attached log). The reason seems to be that the extended fuse byte is not read correctly, because avrdude now read the unused bits as 1, which gives 0XFD instead of 0X05.
