Additionally, the energy-efficient automatic hibernation feature helps conserve battery life by putting the device into sleep mode during periods of inactivity.

Key Features:

• Dual power supply options: Compatible with both a 3V button battery and a 5V USB interface.
• Comprehensive functionality: Supports basic arithmetic calculations and color ring resistance value conversions.
• User-friendly assembly: Clearly marked PCB allows for easy assembly in just 1-2 hours, perfect for beginners.
• Stylish design: Features a transparent acrylic shell that enhances visual appeal while showcasing internal components.
• Energy-efficient: Incorporates an automatic hibernation mode to prolong battery life during inactivity.

Specifications:
Product name: calculator kit
Supply voltage: 3V button battery or USB interface 5V power supply
Product size: 85*119*19mm
Circuit size: 78*105mm

Instructions for Use:
To power on, the calculator defaults to sleep mode. Press the “C” key to activate working mode. If no operation occurs for an extended period, the device will automatically enter sleep mode. In cases of calculation errors or display ranges, an “E” will appear. When both operands are zero, pressing “=” will initiate color ring resistance calculations, with automatic identification of 4-color or 5-color rings.
The upper horizontal digit indicates “Ω”, the middle indicates “kΩ”, and the lower indicates “MΩ”.

Important Notes:
1. Negative number calculations or exceeding the calculation range will result in an error. The color ring resistor conversion function will automatically recognize the number of colors inputted.
2. Do not connect both power sources simultaneously, as this may damage the button battery.
