Precompiled Binaries

You don't need to set up a build environment! We have provided the precompiled .bin files below. You will need to flash all three files to the correct sectors on your ESP32.

Download the attached files:

1. bootloader.bin
2. partitions.bin
3. KryonOS-v1.0.0-esp32.bin

Flashing Instructions

Connect your ESP32 to your computer via USB and use a flashing tool (such as esptool.py or the official ESP Flash Download Tool).
