3pcs 4-Digit LED Display Module with TM1650 Driver 0.36-Inch Common Cathode 5V I2C Interface PH2.0-4Pin Socket 8-Level Brightness Control for Microcontroller Projects
- Includes 3 pieces of 4-digit LED display modules with 0.36-inch red common-cathode digital tubes for numeric display applications.
- Integrated TM1650 driver combines LED driving, data latching, brightness adjustment, and keyboard scanning functions in one chip.
- Uses a 4-wire I2C interface with V/G/D/C connections, reducing wiring requirements compared with traditional digital tube designs.
- The 4-wire control method can save up to 89% of GPIO resources compared with traditional digital tubes requiring more than 12 pins.
- Operates at a typical 5V voltage and provides 25mA segment driving current for the LED display elements.
- Provides 150mA bit driving current to support high-brightness display output in strong-light conditions.
- Offers 8-level programmable brightness adjustment for controlling display intensity through software settings.
- Features a PH2.0-4P socket with an anti-reverse design for the V/G/D/C interface connection.
- Uses a 12-pin package while requiring only four wires for control, combining the stated package structure with simplified module wiring.
