esptool is a Python-based, platform-independent serial utility for flashing firmware, provisioning, and interacting with Espressif SoCs such as the ESP32. It communicates with the chip's ROM bootloader (or an uploaded flasher stub) and can also be used as a Python library.
Use cases
- flash firmware onto an esp32 over serial
- erase the flash memory of an espressif chip
- read the mac address and flash chip id of an esp32
- read and write esp32 efuses
- build and merge binary images for espressif flashing
- provision espressif chips securely with espefuse and espsecure
When to choose
- you are developing or deploying firmware for ESP32, ESP8266, or other Espressif SoCs
- you need a scriptable, cross-platform flashing tool that also works as a Python library
- you need low-level access to eFuses, flash contents, or chip info
When to avoid
- you are flashing microcontrollers from other vendors such as STM32, AVR, or RP2040
- you need a graphical flashing interface rather than a command-line tool
- you are not working with Espressif hardware
