Nuvoton’s new true color temperature controller reference design provides complete solutions, starting from the hardware design, using the graphics control series N9H20 microprocessor and built-in 32 MB SDRAM memory, reducing hardware design difficulties.

This solution provides a complete hardware circuit design and PCB layout. In addition, a full graphic of the temperature controller is provided in software design, which includes the power-on screen show, three-page slide mode switching, temperature display, temperature control, perpetual calendar, backlight control, and RS485 control. Furthermore, the software uses open-source so users can change the process and pictures according to their plans, and users can directly download and use related graphics.
