Serial 4-Digit LED Display Module – CLOCK Version SLEDC4C

Clock Model: controllable 2-LED colon in center of display for time format (right-hand decimal points disabled)

Standard (No Clock) Model Available

The SLED-C4 from Reynolds Electronics provides a simple asynchronous serial interface to a high contrast, four-digit, seven-segment, super red LED display module – with 6 unique built-in animations. The display can be driven with a single pin from your microcontroller.

• 6 unique, built-in display animations for printing, scrolling, clearing digits, and other special effects
• Flicker-free multiplexed LED display with fast response times
• Available with 4 right-hand decimal points, or clock type display with 2 colon LEDs
• Two command modes for total control of individual LED segments
• Animation speed control for enhanced creative freedom and custom effects
• Stores display brightness setting in onboard non-volatile memory for automatic power-up brightness setting
• Stores a four-digit splash screen in onboard non-volatile memory for automatic display at power-up
• Eliminates the need for continuous display updates and refresh loop in the host controller’s firmware
• Simple, single-wire asynchronous serial control with pin-selectable data rates of 9600 or 19200 bps
• Automatically refreshes and updates each display digit at ~1.2KHz
• Low-power sleep mode current draw <100uA typical, with automatic display restore on wake-up
• Flexible operating voltage range from 4.5 to 5.5 VDC
• Small footprint PCB measuring only 2.4″ x 1.2″
• 2KHz PWM brightness control with 126 levels: 0 = off, 125 = max brightness
• Multiplexed display digits for reduced power consumption
• Auxiliary digital output pin signal end of onboard animation sequence, or may be used as digital output when built-animations are not used
• RoHS Compliant: YES
