This is a pcb design for the 0.80" LED 7-Segments Display Module. The board is pin compatible with the standard 0.56" LED 7-Segments Display Module
This hardware module is supported by a native C++ driver implementation (linked below), demonstrating a full-stack IoT approach from physical PCB to firmware abstraction.
Reflowed using a controlled hotplate process with lead-free solder paste (SAC305). The screen was hand soldered using a standard soldering iron. The screen can be attached directly or socketed.
- Display numbers
- Display raw segment data
- Scrolling text
- Simplified interface
- C++ Implementation
