K3ng Keyer Schematic Repack Jun 2026

In keyer_pin_settings.h , ensure the pin numbers match your wiring (e.g., #define left_paddle_pin 2 ).

Adding an LCD or OLED is highly recommended for monitoring speed, memories, and settings. The K3NG code supports various displays: SDA → A4, SCL → A5. OLED (SSD1306): SDA → A4, SCL → A5. Memory Buttons k3ng keyer schematic repack

You’re operating 100W and the keyer locks up on transmit. A good repack includes RF mitigation strategies: shielded cables, RC snubbers on the key line, and proper grounding planes. The original schematic does not emphasize this. In keyer_pin_settings

The K3NG software is extensive. A "repacked" understanding involves knowing which files to edit first: The main project file. OLED (SSD1306): SDA → A4, SCL → A5

So, you have a schematic, and you're ready to build. How do you move from theory to practice?

Beyond the electrical connections, the schematic repack emphasizes "Design for Manufacturability" (DFM). In the original scattered diagrams, component placement was often abstract. A repacked schematic usually leads to a single-sided PCB design or a clear stripboard layout.
