Frequently asked questions
Which AVR chips can I program with it?
It works with AVR microcontrollers that have a JTAG interface. Many small AVR chips use debugWIRE or ISP instead, so check your chip's datasheet for JTAG support before buying into this workflow.
Which software is used with this programmer?
AVR JTAG ICE tools are typically used with Microchip Studio (formerly Atmel Studio) for programming and debugging. Connect the target's reference voltage to the tool so the signal levels match, especially for 3.3 V boards.
