Product Overview
NoseDisplay ND021TRN480480-A01 is a round IPS TFT LCD module for smart home controls, appliance interfaces, instrument dials and embedded IoT devices. Its circular display offers a practical format for menu navigation, sensor readings, equipment status screens and compact HMI designs in custom OEM products. The ST7701 controller uses SPI configuration with an RGB display interface; projects based on STM32, ESP32, Arduino or Raspberry Pi require suitable host hardware, firmware and power circuitry. NoseDisplay supports FPC integration, cover lens options and adapter board evaluation to help engineers develop circular LCD interfaces for their enclosure and application.
