1.54 Inch E-Paper Display Module, Four Color E-Ink Screen SPI Interface for DIY Electronics Shelf Label Project, DIY Weather Station Clock Project
[Product Introduction]
The 1.54inch E-paper Module integrates four-color e-paper display, fast refresh response, and multi-interface connectivity, providing an easy-to-integrate display solution for electronic price tags, IoT information terminals, and embedded development projects. It supports 3-wire/4-wire SPI switching and is compatible with various main controller development requirements.
[Product Features]
1. Four-color information display: 1.54-inch, 200(H) × 200(V) pixel display, supporting black, white, yellow, and red images, making it convenient to distinguish different types of display information.
2. Clear ambient-light reading: Reflective, backlight-free e-paper features high contrast and a wide viewing angle, suitable for viewing content under ambient light.
3. Fast content updates: At 25°C, the panel fast refresh time is approximately 12 seconds, suitable for periodically updating status and information.
4. Low-power content retention: The module supports sleep mode; the bistable display of e-paper can reduce power consumption while maintaining static content.
5. Multiple connection methods: The module provides flexible main controller connection options, suitable for the wiring requirements of different embedded projects.
6. Onboard signal adaptation: An integrated level-shifting buffer provides adaptation for signal connections between the module and the main controller.
7. Flexible SPI configuration: Supports 3-wire/4-wire SPI switching, allowing the connection method to be selected according to the main controller communication requirements.
8. Onboard level-shifting chip, compatible with 3.3V and 5V microcontroller interfaces.
[Application Scenarios]
1. Electronic price tags and shelf information boards: Used to display low-frequency update content such as prices, product information, inventory status, or asset identification.
2. IoT device information terminals: Works with Arduino, ESP32, ESP32-S3, or Raspberry Pi to display sensor data and device operating status.
3. Embedded development learning: Used for learning and prototype verification of e-paper driving, SPI communication, and display programs.
