What's better than a simple LED? Many LED! Fun a way to achieve a linear display is to use 2 bargraph to 12 LEDS. The bar graphs being multiplexes, it will take a lot of pine trees to fly 48 LED it ets so for this that a LED MAX7219 controller has been integrated also on the circuit, allowing an I2C cockpit with only two wires of sigaux.
