Description

The DFRobot Gravity IO Shield is a dedicated expansion board that simplifies prototyping and system integration for the FireBeetle 2 series of development boards. It provides a standardized Gravity connector interface, allowing direct plug-and-play connection with DFRobot’s extensive ecosystem of Gravity sensors, actuators, and modules. This eliminates the need for soldering or complex wiring, accelerating project development.

The shield breaks out all critical microcontroller pins, including digital I/O, analog inputs, I2C, UART, and SPI buses, ensuring full access to the FireBeetle 2’s capabilities. It includes an external PH2.0 power input socket (3.3V to 5.5V) for supplying power independently to connected modules, and an EN pin for controlling the main board’s power supply, which is useful for low-power portable applications. The board also integrates a GDI interface for connecting DFRobot’s graphical display modules.

Key Features

  • Precision-engineered form factor for FireBeetle 2 ESP32-E and M0 series
  • Standardized Gravity interface for solderless sensor and module integration
  • Comprehensive pin breakout: digital, analog, I2C (x2), UART, and SPI
  • Dedicated external power input port (PH2.0, 3.3~5.5V) for peripheral supply
  • Integrated EN control pin for main board power management
  • GDI interface port for direct connection to DFRobot display modules
  • High-quality PCB with clear silkscreen labeling for easy prototyping
  • Optimized for portable and battery-powered IoT project development

Frequently Asked Questions

Is this IO Shield compatible with the original FireBeetle ESP32 board?

No, this Gravity IO Shield is specifically designed for the FireBeetle 2 series, including the ESP32-E and M0 models. The pinout and form factor are tailored to these boards. It is not compatible with the first-generation FireBeetle ESP32 due to differences in pin layout and physical dimensions.

What is the purpose of the external PH2.0 power input port?

The external PH2.0 power input (3.3V to 5.5V) allows you to supply power directly to the shield and its connected Gravity modules, independent of the FireBeetle 2's main power. This is useful for powering high-current sensors or for creating portable setups where you want to control peripheral power separately from the microcontroller to conserve battery life.

Can I use non-DFRobot (3rd party) sensors with this shield?

Yes, you can use third-party sensors, but not directly via the Gravity connectors. The shield breaks out all standard GPIO pins (digital, analog, I2C, UART, SPI) to standard 0.1" headers. You can wire any sensor to these headers. The Gravity interface is a convenience feature specifically for the plug-and-play DFRobot Gravity sensor ecosystem.

How do I use the EN pin for power control?

The EN pin on the shield is connected to the Enable pin of the FireBeetle 2. By pulling this pin low (e.g., using a digital output from another controller or a switch), you can cut power to the main FireBeetle 2 board while potentially keeping power on the shield and its peripherals via the external PH2.0 input. This enables ultra-low-power sleep modes or remote power cycling.
