The DFRobot FireBeetle series is a low - power consumption micro - controller family designed specifically for the Internet of Things (IoT). It focuses on low - power IoT nodes, enabling users to quickly and conveniently build IoT hardware platforms. There are three types in the series: Boards (main control), Covers (expansion boards), and related Accessories. The FireBeetle Gravity I/O Expansion Shield serves as an adapter for Gravity sensors and modules. With this shield, you can easily connect Gravity sensors to FireBeetles, and each sensor gets its own power pins. Note that it only works at 3.3V (red pins). Key features include compatibility with DFRobot FireBeetle, a Gravity interface for easy plug - and - play use, high cost - effectiveness, and a small size for convenient installation. Specifications: Input voltage ranges from 3.7V to 5.5V (VCC), output voltage is 3.3V, it supports low - power consumption mode when POWER_EN = LOW, has a maximum discharge current of 600mA at LDO - 3.3V output voltage, uses a Gravity standard interface, has 10 digital I/O pins, 5 analog input pins, and supports I2C, UART, and SPI interfaces. Its dimensions are 29.00x58.00mm/1.14 x 2.28 inches. The shipping list includes one FireBeetle Gravity I/O Expansion Shield, two 18 - pin 2.54mm pins, and two 18 - pin 2.54mm long pin headers.






Using the FireBeetle Gravity I/O Expansion Shield is a breeze. First, make sure your power source has an input voltage between 3.7V and 5.5V. Remember, the output voltage is 3.3V only, so check those red pins. To connect your Gravity sensors, simply plug them into the Gravity interface on the shield. It's plug - and - play, so you don't have to worry about complex setups. When it comes to power, if you want to use the low - power consumption mode, set POWER_EN to LOW. Keep in mind that the maximum discharge current is 600mA at an output voltage of LDO - 3.3V. For maintenance, store the shield in a dry and clean place. Avoid exposing it to extreme temperatures or humidity. If you're not using it for a long time, remove the power source to prevent any potential damage. Also, handle the shield gently as it has small components that can be easily damaged. And that's all you need to know to get the most out of your FireBeetle Gravity I/O Expansion Shield.
