상품 특징
- Package: This display driver is in a compact SOP-20 package, ideal for controlling 7-segment LED displays in clocks, meters, and other consumer electronics.
- Function: A dedicated LED drive control circuit with a simple two-wire serial interface. It can directly drive up to 8 segments by 6 grids (e.g., for a 4-digit clock display).
- Working Voltage: It operates from a supply voltage of 3.3V to 5.5V, allowing direct connection to 3.3V or 5V microcontrollers like Arduino and ESP8266/32.
- Working Current: The chip itself has low power consumption. It includes internal pull-up resistors and can drive LEDs with adjustable brightness levels to save power.
- Pin Function: The key pins are the two-wire serial interface (DIO for data, CLK for clock), and the segment/grid outputs for connecting to the LED display digits.
