NORVI ESP-HMI-5C ESP32-based HMI features a 5-inch resistive touchscreen display

NORVI ESP32-based human-machine interface (HMI) solution features a 5-inch LCD with a resistive touchscreen driven by an ESP32-S3 wireless module and support for the LVGL library.

NORVI previously brought us some headless ENET industrial controllers including some with Ethernet beside the WiFi connectivity built into the ESP32 microcontroller, but the NORVI HMI device is the first product from the company with a proper display suitable for HMI applications.

The NORVI HMI device can be programmed with the Arduino IDE, MicroPython, or the ESP-IDF framework. It supports the popular LVGL library and Squareline Studio for graphical user interface design. The company expects it to be used for industrial process control, energy management, transportation, healthcare, Smart Home, public infrastructure management, and in consumer devices and as a simple process controller. Software documentation includes a getting started guide for Arduino programming and an LVGL demo that looks to be the same as in the Elecrow ESP32 Terminal.

The NORVI ESP-HMI-5C can be purchased for $125 plus shipping on the company’s online store, and a few more details may also be found on the product page.
