Hey everyone! We're excited to introduce a new addition to the Gravity family - the Flexible 8x8 RGB LED Matrix. It's a square panel with a pre - soldered XH2.54 3 - pin interface that fits perfectly with the Arduino I/O expansion shield. This module uses WS2812 or SK6812 intelligent control LEDs. Each LED can be controlled independently with RGB pixels, offering 256 levels of brightness and a whopping 16777216 colors. The scanning frequency is at least 400Hz! The LED panel is a single - wire control board. We've provided a special cable so you can connect it to Arduino I/O expansion shields without soldering. It also supports cascading control. Just connect Din to the DOUT port. With the open - source Arduino library, you can control a whole LED array using just one pin! Note: Each LED needs a max current of 18mA. When using multiple modules, it's best to power them via the Servo Power Port on the DFRobot Gravity IO expansion board. Features include full - color RGB, cascade control support, Gravity interface compatibility, and external power supply support. Specifications are an operating voltage of 5V, LED types of SK6812/WS2812, a Gravity 3 - pin communication interface, an operating temperature range of - 25 to + 80 °C, dimensions of 80*80 mm (3.15*3.15 inches), and a weight of 130g. Shipping includes one flexible 8x8 RGB LED Matrix, one matrix Gravity interface cable, and one DC Barrel Jack Adapter - Female.
Using this flexible 8x8 RGB LED Matrix is a breeze. First, connect it to your Arduino I/O expansion shield using the provided special cable. No soldering is needed. If you want to control multiple matrices, connect the Din of one matrix to the DOUT port of another for cascading control. Then, use the open - source Arduino library to control the LEDs with just one pin. When it comes to power, remember that each LED needs a maximum current of 18mA. If you're using multiple modules, it's a good idea to use the DFRobot Gravity IO expansion board and power the matrices via the Servo Power Port. As for maintenance, keep the matrix in an environment with a temperature between - 25 and + 80 °C. Don't expose it to extreme heat or cold. Also, handle it gently to avoid damaging the LEDs or the interface.
