Free public beta until December 4, 2026: every course is open, no card needed. After that, the first chapter of each course stays free and full access is a one-time $39 ($19 for up to 100 founding members chosen for helpful feedback). Your progress is kept. How the beta works

firmware image

The compiled program as one binary file that gets written to flash.

A firmware image is the linked application binary, with its header and segments, that is written to an app partition and loaded by the bootloader.

Examples

  • The lab sketch's firmware image for the ESP32-C6 is one binary file of 1,154,020 bytes that the device downloads and writes to its flash.

  • An image built for the ESP32-C6 must never be installed on an ESP32-S3, so the manifest names the chip it was built for.
