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

over-the-air update

Replacing a device's firmware through its own network connection.

An over-the-air update downloads a new firmware image over the device's network link, writes it to flash and switches the device to it, without physical access.

Examples

  • Instead of a day with a USB cable for each of the greenhouse's 160 fan controllers and soil sensors, an OTA lets every board download and start a new release over Wi-Fi.

  • A TLS library fix found years after shipping reaches the fleet only because each device can update over the air.
