ESP32N2K Flasher

ESP32N2kFlasher is a utility app for the esp32nmea2000 gateway framework and is designed to make flashing the firmware as simple as possible by:

• Having pre-built binaries for most operating systems.
• Hiding all non-essential options for flashing.

The Project is based on ESPHome-Flasher project.

The flashing process is done using the esptool library by espressif.
