Feature:

USB Connectivity: The USBASP programmer connects to your computer via a USB interface. This allows for faster data transfer rates and simplifies the connection process.

In-System Programming (ISP): The programmer supports in-system programming, which means it can program the microcontroller while it is still connected to the circuit it's a part of. This eliminates the need to remove the microcontroller for programming.

Multiple AVR Support: USBASP is compatible with a wide range of AVR microcontrollers from Atmel/Microchip, including various models from the ATmega and ATtiny series.

External Power Source: Some USBASP programmers can provide power to the target board externally, ensuring that the target microcontroller receives the necessary power during programming.

Easy-to-Use Software: The programming process is usually controlled through a software interface on your computer. The popular software for using USBASP is Avrdude, which is a command-line tool for programming AVR microcontrollers.

Target Voltage Selection: The programmer allows you to select the appropriate voltage level for your target AVR microcontroller, ensuring proper programming and compatibility.

Programming Indicator LEDs: Many USBASP programmers have indicator LEDs that provide feedback about the programming process, helping you monitor the progress and identify any issues.
