USBtinyISP is designed for AVRthrough a USB by means of the ISP connection. USBtinyISP is supported by the normal Arduino IDE and can be used to burn Arduino code bootloader onto chips (any Atmel AVR microcontroller). The Tiny ISP Programmer is able to provide the 5V power supply voltage to the board being programmed. If you want to power the board through the ISP you have to close the SJVCC jumper on the board. With this programmer you can upload sketches and burn the bootloader on any AVR based boards, including for Arduinos. By uploading a sketch with an external programmer you can remove the bootloader and use the extra space for your sketch. The for Arduino ISP can also be used to burn the for 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 for Arduino, and you wish to use the bootloader to upload a sketch via the USB-Serial connection. Supports ATTiny45 and ATTiny85 chip for arduino programming,etc.
