The AVR USBASP Programmer is a USB in-system programmer (ISP) designed for programming Atmega and Atmel microcontrollers. It provides a direct USB interface for writing firmware to MCU flash memory, supporting 10-pin and 6-pin ISP headers. The programmer is compatible with Windows, Linux, and macOS platforms and operates without an external power supply, drawing power from the USB port. It supports high-speed programming with reliable data transfer and is widely used in embedded systems development, firmware updates, and microcontroller prototyping.
