Description:

With this USBTinyISP programmer you can upload sketches and burn the bootloader on any AVR based boards, including Arduinos.
By uploading a sketch with an external programmer you can remove the bootloader and use the extra space for your sketch.
This Programmer can also be used to burn the Arduino bootloader, so you can recover your chip if you accidentally corrupt the bootloader.
Burning the bootloader is also necessary when you use a new ATmega microcontroller in your Arduino, and you wish to use
the bootloader to upload a sketch via the USB-Serial connection.

Package included:

3 x AVR ISP ATtiny44 USBTinyISP Programmer Arduino Bootloader
