Product Description MAX7219 8-Digit 7-Segment Digital LED Display Overview: This 8-digit red LED numeric display is driven by the MAX7219, using an SPI interface requiring three I/Os. The MAX7219 is an integrated serial input/output common-cathode driver, between the LEDs and the microcontroller. Only one external register is used to set the current of each LED segment. This device was added to Parallax inventory as a quick demonstration to the sample code for the Propeller 2 SPIN/PASM SPI Driver used in the Propeller 2 Live Forum and P2 Quick Byte “SPI Driver Object”. It is compatible with all Parallax microcontrollers, to provide simple visual feedback for numbers and data. MAX7219 8-Digit 7-Segment Digital LED Display Features: Compatible with 3.3V and 5V microcontrollers Measures 0.375” x 3.250” in size with 0.36” tall displays. 150 mA low-power shutdown mode Includes 5-pin straight and right-angle headers for soldering by customer MAX7219 8-Digit 7-Segment Digital LED Display Wiring instructions: Vcc: 5VDC GND: GND DIN: P0 CS: P1 CLK: P2
