Description

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.

Each module has an address selectinnable for den mount 8 on the same I2C bus.

All is sold in kit form and will require a little welding to implement.

Features

• Bar graph dimensions: 10mm x 30mm (0.4 "x 1.2")
• Thickness: 7mm (0.3 ")
