It uses an SPI interface and is designed for Arduino, ESP32, Raspberry Pi and similar controllers. The display is bistable — it holds the last image with zero power and only draws current during refresh — making it ideal for static signage, price labels, and low-power dashboards where colour highlights are needed.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDisplay size: 3.7 inches diagonal\u003c\/li\u003e\n\u003cli\u003eResolution: 416 x 240 pixels\u003c\/li\u003e\n\u003cli\u003eColours: Red, Yellow, Black, White\u003c\/li\u003e\n\u003cli\u003eInterface: SPI (4-wire)\u003c\/li\u003e\n\u003cli\u003eOperating voltage: 3.3V (logic level)\u003c\/li\u003e\n\u003cli\u003eRefresh time: ~15 seconds (full refresh)\u003c\/li\u003e\n\u003cli\u003eViewing angle: \u0026gt;170°\u003c\/li\u003e\n\u003cli\u003eModule dimensions: 96.4 x 67.5 mm (display area: 81.1 x 46.8 mm)\u003c\/li\u003e\n\u003cli\u003eDriver IC: SSD1680\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eCompatible with\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eArduino (Uno, Mega, Due, Leonardo)\u003c\/li\u003e\n\u003cli\u003eESP32 \/ ESP8266\u003c\/li\u003e\n\u003cli\u003eRaspberry Pi (any model with SPI)\u003c\/li\u003e\n\u003cli\u003eSTM32\u003c\/li\u003e\n\u003cli\u003eTeensy\u003c\/li\u003e\n\u003cli\u003eAny microcontroller with SPI and 3.3V logic\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhat you can build with it\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRetail shelf labels and price tags with colour highlights for promotions\u003c\/li\u003e\n\u003cli\u003eMeeting-room occupancy signs showing free\/busy status\u003c\/li\u003e\n\u003cli\u003eLow-power weather dashboard or stock ticker that updates periodically\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eBuilt and Backed by Compoden\u003c\/h2\u003e\n\u003cp\u003eEvery Waveshare display from Compoden comes with an AI build companion — delivered via QR, email, or WhatsApp — that helps you wire and program this part into a working project.
