Features and Specifications

• Two-digit high-brightness seven-segment display
• Easily view a counter or timer
• Common Cathode configuration
• 1.0" × 1.7" (2.5 cm × 4.3 cm) PCB size
• Two 6-pin Pmod connectors
• GPIO Bus interfaces
• Follows Digilent Pmod Interface Specification Type 1 (general purpose logic)
• 3.3V Logic Level

The PmodSSD model utilizes a common cathode configuration to display a variety of LED segment combinations. The ten segment combinations corresponding to digits 0 - 9 are generally the most useful, although other custom combinations can also be created. The Pmod SSD is a two-digit seven-segment display. Users can toggle through GPIO signals which digit is currently on at a rate of 50 Hz or greater to achieve persistence-of-vision to give the effect of both digits being lit up simultaneously.

The Pmod SSD uses the Pmod Interface Type 1 (GPIO) which is used for general purpose logic. The host must provide the ability for all signals to be bi-directional logic signals. The peripheral may use any of the pins as inputs, outputs, or bi-directional. Should a PWM signal be used, it should be on pin 2.

Pmod Series Overview

The Digilent Pmod (peripheral module) Series is a small, low-cost peripheral module that can be used with a wide range of embedded systems and development boards. It is designed to extend the capabilities of embedded systems and development boards by adding new features and functionality. The Pmod communicates with host boards using 6, 8 or 12-pin connectors that can carry multiple digital control signals, taking advantage of standard serial protocols such as SPI and I²C. This allows for more effective designs by routing analog signals and power supplies only where they are needed and away from digital controller boards.
