ITEAD has sent us samples of the Open Nextion ONX3248G035 and ONX2432G028 ESP32-S3 HMI displays for review. Open Nextion is a new product line that differs from the original Nextion HMI family, which relies on the Nextion Editor for UI design and UART communication for control. Instead, the Open Nextion features an ESP32-S3 wireless microcontroller handling logic processing, display control, and wireless connectivity, all in one integrated package. ITEAD fully supports the ESP-IDF framework and the Arduino IDE with LVGL graphics library support. The ONX3248G035 model features a 3.5-inch screen, while the ONX2432G028 variant has a 2.8-inch screen. The Open Nextion HMI wireless displays also take accessories such as a dual-microphone array, a speaker, and an I/Os adapter. The new Open Nextion product line is especially well-suited to embedded developers/makers who want an all-in-one board with HMI and wireless capabilities, IoT terminal and Smart HMI panel prototyping, students interested in […]
