What is the power consumption of the LCD?
The power consumption of the I2C 2004 LCD module is typically low, with the following specifications:
Supply Voltage: 5V
Typical Operating Current:
Without backlight: Approximately 1-2 mA
With backlight: Approximately 20-40 mA
Power Consumption Calculation:
Without Backlight:
Power = 5V × 0.001A = 0.005W (5 mW)
With Backlight:
For example, at 20 mA, Power = 5V × 0.020A = 0.1W (100 mW)
Summary:
Without Backlight: Approximately 5 mW
With Backlight: Approximately 100 mW
The power consumption may vary depending on specific usage, but overall, it remains within a low power range.
