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)
The schematic for this design can be found in the docs/schematic.pdf file.

This PCB can be used with any FPGA or microcontroller board, although it uses a non-standard pinout (for PMODs). The multiplexed design allows for efficient control of both digits using minimal GPIO pins.
We welcome contributions to improve this design. Please feel free to submit issues or pull requests.
This design is inspired by the Digilent PMOD 7-segment display but has been modified to fit a custom board and does not conform to the normal PMOD pinout.
