FireBeetle LED Matrix White SKU DFR0484 Introduction FireBeetle Covers-24x8 LED Matrix DFRobot FireBeetle is a low-power consumption micro-controller intentionally designed for Internet of Things IoT . This series micro-controllers aims at IoT node of low-power consumption, attending to build the IoT hardware platform quickly and conveniently. There are three types of FireBeetle, containing Boards main control , Covers expansion boards and related Accessories. This 24x8 LED Matrix display is special designed for FireBeetle series. It supports low-power consumption mode and scrolling display. With HT1632C high performance LED driver chip, every led has independent register, which makes it easy to drive separately. It integrates a 256KHz RC clock, only 5uA under low-power mode, support 16 scale PWM brightness adjustment. This product also works with the other Arduino micrcontroller like Arduino UNO. Specification • Operating Voltage 3.3~5V • LED Color Single color White/Blue/Yellow/Red/Green • Drive Chip HT1632C • Working Current 6~100mA • Low-power Consumption 5uA • RC clock 256KHz • Chip Select CS D2, D3, D4, D5 selectable • Serial Data Communication • Support Arduino Library • Support Scrolling display • Interface mode FireBeetle Series Compatible • Operating Temperature -10 ~+85 • Dimension 24 x 58 mm /0.94 x 2.28 inches • Weight 26g FireBeetle Covers-24x8 LED Matrix Chip Select Note FireBeetle Covers-24x8 LED Matrix has 4 CS pin, you can select the CS from the dialing switch, and one FireBeetle can control 4 LED matrix at the same time. Board Overview FireBeetle Covers-24x8 LED Matrix Num Label Description 1 DATA 2 WR 3 CS 4 RD 5 VCC Generally Not Used D3, D4, D5 selectable Battery Tutorial In this section,we will demonstrate several example about how to use this LED matrix. Requirements • Hardware FireBeetle Board - ESP32 x 1 FireBeetle Covers-24x8 LED Matrix x1 • Software Arduino IDE Click to Download Arduino IDE from Arduino Library Github Sample Code Hello Note You need use D x to call digital I/O pins under Arduino IDE. Or that will be IO x .
