The easiest might be something like an i2c IO expander, which would give you N outputs for 4 wires (SDA, SCL, Power, Ground). IO expanders […]

You can put testing rigs right on the panel. You can combine different boards to reduce your PCB production cost. But Eagle, Fritzing, and KiCad don’t have […]
