| - | AVRDUDE is a command line tool to program AVR chips. It runs in the background of the Arduino IDE. Sometimes it is necessary to erase a chip or set the fuse bits that's when the AVRdude comes handy. | ||

| - | **ATmega32U4**\\ | ||
| - | To erase the chip: | ||
| - | sudo avrdude -p m32u4 -c stk500v2 -P /dev/ttyACM0 -e -F | ||
| - | |||
| - | **ATmega328p**\\ | ||
| - | To erase the chip: | ||

| - | | ||
| - | **Atmega8u2**\\ | ||
| - | It is the chip for serial to USB on the Arduino Uno and on the Usb2Serial board. | ||
| - | >On the Arduino Usb2Serial Light Board the ISP header is marked wrong, pin 1 is the nearest one to the Atmega8u2 chip. | ||
