## What it is
AVRDUDE is a command-line utility for downloading and uploading on-chip memories (Flash, EEPROM, fuse and lock bits) of AVR microcontrollers. It supports many programming protocols and hardware programmers, including Arduino bootloaders.

## Use cases
- flash a hex firmware file onto an Arduino Uno
- read the EEPROM contents of an ATmega chip
- burn fuse bits on an ATtiny microcontroller
- upload sketches to AVR boards from the command line
- verify firmware written to a microcontroller
- issue raw programming instructions to an AVR chip

## When to choose
- you need to program or read AVR microcontroller memories from the command line
- you want to flash Arduino boards outside the Arduino IDE
- you need support for many ISP programmers and protocols
- you want to automate firmware flashing in build scripts or CI

## When to avoid
- you need to program non-AVR chips like ARM Cortex microcontrollers (use OpenOCD or vendor tools)
- you want a graphical flashing interface
- you only need to compile AVR firmware without uploading it

## Facets
- artifact type: cli-tool
- maturity: active
- function: cli, developer-tools, embedded
- domain: embedded-systems, hardware, developer-tools
- platform: windows, cli, cross-platform
- tags: avr, microcontroller, arduino, firmware-flashing, isp-programming, atmel, microchip, command-line, linux, macos
