Core Configuration

• ​Main Controller: ATmega32U4 microcontroller, compatible with Arduino ecosystem development, providing a stable low-power operating environment.
• ​Display Solution: 1.3-inch IPS LCD screen with precise color accuracy and wide viewing angles, complemented by a 25.4mm optical prism design that creates holographic light refraction effects for a floating 3D visual experience.
• ​Enclosure Design: Industrial-grade 3D print material with precision optical coating on the prism components, balancing technological aesthetics with artistic appeal, suitable for various desktop scenarios (e.g., study desks, office spaces, home decor).

Key Functional Highlights

1.​Developer-Friendly: - Supports Arduino IDE and AVR Studio development environments, complete with hardware schematics and SDK, enabling customization of photo galleries, dynamic effects, and sensor integrations (e.g., light/temperature/humidity sensors). - Pre-configured GPIO expansion interfaces for external storage or smart device connectivity.

2.​Desktop Photo Interaction

• Any 240x240 photo can be uploaded via a computer.

3.​Low Power

• Utilizes ATmega32U4 sleep mode and screen dynamic refresh technology, consuming less than 20mA in standby, ideal for extended desktop displays.

Applicable Scenarios

• Personalized Desktop Decor: A tech-inspired photo frame for showcasing travel, milestone memories, or themed collections with prism-enhanced ambiance lighting.

• Smart Home Control Hub: Connects to platforms like Home Assistant via secondary development for touch-controlled lighting/air conditioning.

• Educational Development Kit: Perfect for students or hobbyists to learn embedded systems, sensor applications, and human-machine interaction design.
