The DFRobot FireBeetle series offers a versatile microcontroller tailored specifically for Internet of Things (IoT) applications. Designed to minimize power consumption, this series enables the rapid and straightforward construction of IoT hardware platforms. It comprises three main components: Boards for primary control, Covers for expansion, and a range of compatible Accessories. This structure ensures a flexible setup for diverse IoT projects.
One standout accessory is the 24×8 LED Matrix display, engineered exclusively for the FireBeetle series. It is ideal for those requiring a low-power consumption solution with capabilities like scrolling text. Equipped with the HT1632C, a high-performance LED driver chip, each LED features an independent register, allowing for precise control. Additionally, its integrated 256KHz RC clock operates with remarkable efficiency, drawing only 5 microamperes in low-power mode, and supports 16 levels of PWM brightness adjustment.
This LED Matrix is compatible not only with FireBeetle mainboards but also with other Arduino microcontrollers, such as the Arduino UNO, broadening its utility. A popular use case is the creation of a DIY Deer Clock project. In this charming application, the LED display showcases time in an engaging and visually appealing manner. Essential components for this project include the Gravity I2C SD2405 RTC Module, the compact Beetle Arduino board, and the FireBeetle Covers-24x8 LED Matrix, all connected via a standard Micro USB cable.
