A compact, touchscreen‑based control module built on the ESP32‑2432S028 Cheap Yellow Display (CYD) platform. Each unit arrives fully prepared with the Avalon Nano Ultra Controller firmware preinstalled and verified, giving you a ready‑to‑use interface immediately on first power‑up. Case shown in images is not included.
This device includes firmware created and distributed by its original developer. Full documentation, licensing details, and source material are available on the project page: https://github.com/Stu1958/Avalon-Nano-Ultra-Controller
The installed firmware operates in trial mode. A paid license from the firmware’s developer is required to unlock full functionality. No license or activation key is included with this hardware. The firmware is provided exactly as released by the author - no modifications, support, or activation services are included.
From the project GitHub:
Test the full interface for free. The trial offers 100% functionality so you can verify the thermal improvements before you buy.
When installed connect to the NanoCtrl-AP WiFi (Password: config123). Open a browser to 192.168.4.1 and click Configure WiFi.
Enter your WiFi credentials, Nano name and IP address press save and the CYD will reboot and start managing your Nano's Tmax immediately.
60-Minute Stress Test: The controller will manage your Tmax automatically. Reset the trial as many times as you like for continued testing!
