ESP Offline Flasher is a tool specially designed to program ESP32 microcontrollers, for example, firmware flashing, without the need for a computer or any external software. It stores firmware files on a 4 GB internal EMMC chip that can be accessed as a USB mass storage device, and configuration can be set using a CSV file. ESP Offline Flasher can power ESP32 target boards or it can be powered from the target board. Simply press the push button to detect the target board and start the flashing process. An RGB LED indicator shows whether the flash verification was successful or not.
