FireBeetle Covers-Gravity I/O Expansion Shield

This FireBeetle Covers shield is an adapter for Gravity sensors and modules. It brings the pins of a FireBeetle board out to Gravity connectors, each sensor connector has its own power pins. Sensors can thus be connected via the plug connections without soldering.

Recommended Accessories:

• FireBeetle ESP32 IOT Microcontroller with WiFi
• FireBeetle ESP8266 IOT Microcontroller with WiFi
• Gravity 3pin Digital Sensor Cables for Arduino 10 pieces
• Gravity 3pin Analog Sensor Cable for Arduino 10 Pieces
• Gravity 4pin IIC/I2C/UART Sensor Cable for Arduino 10 Pieces

Features:

• Marked FireBeetle Covers Gravity Adapter Board V2.0
• Colour-coded pins for signal, 3.3 V and GND on D0 to D9 and A0 to A4
• With POWER_EN = Low the 3.3 V pins are switched to 0 V for low-power operation, default is High
• SPI SS selectable on D2, D3, D4 or D5 via the DIP switch
• RST button

Application Examples:

• Connect Gravity sensors to the FireBeetle without soldering
• Low-power sensor nodes, switching sensors off via POWER_EN
• Prototypes with several sensors
