Frequently Asked Questions

Q: What microcontrollers does the Micro USB USBTinyISP AVR ISP Programmer support?

A: The USBTinyISP AVR ISP Programmer supports a wide range of Atmel AVR microcontrollers, including the ATtiny44, ATtiny45, ATtiny85, ATmega328P, and many other ATtiny and ATmega series chips. It is compatible with any microcontroller supported by the standard AVRISP protocol and AVRdude software.

Q: Is this AVR ISP Programmer compatible with the Arduino IDE?

A: Yes! The USBTinyISP programmer has official support in the Arduino IDE. You can select "USBtinyISP" as your programmer under Tools > Programmer in the Arduino IDE to burn bootloaders or upload sketches to bare AVR microcontrollers without a separate bootloader.

Q: Does the programmer power the target board during programming?

A: Yes. The Micro USB USBTinyISP AVR ISP Programmer can supply a 5V power output to the target board being programmed, eliminating the need for a separate power source in many setups. This makes it especially convenient for standalone chip programming.

Q: What software drivers are required to use this programmer?

A: On most modern operating systems, the USBTinyISP programmer requires minimal driver setup. For Windows, you may need to install a libusb-based driver (such as via Zadig). On macOS and Linux, it is generally recognized automatically. Detailed setup guides are widely available from the Arduino community.
