From the project

Simple module for a two-digit 7-segment display

This repository contains the design files for a 2-digit 7-segment display PMOD, modeled after the Digilent PMOD design but without a dual-row Dupont male header pinout. The display is designed for 3.3V operation and uses multiplexing to control both digits using only 8 GPIOs (7 for segments, one for left/right digit select).

- 2-digit 7-segment display - 3.3V operation - Multiplexed design (8 GPIOs control both digits)
