The figure above shows all external connectors on the EFR32xG24 Explorer Kit, including USB Type-C interface, Breakout Pads, mikroBUS socket, and Qwiic connector. These connectors serve as core interfaces for connecting external devices, debugging tools, and expansion modules, enabling hardware expansion and functional development.

Connector Classification and Functional Details

1. USB Type-C Connector

  • Location: Centrally positioned at the bottom of the development board
  • Functions:
    • Power Supply: Provides 5V input via USB, which is converted to 3.3V (VMCU) by the onboard LDO regulator to power the entire board.

2. Breakout Pads

  • Location: 10 pins on each the left and right sides (20 pins total)
  • Functions:
    • Hardware Expansion: Exposes GPIO, I2C, SPI, UART, and other peripheral pins of the EFR32MG24 for custom hardware connections.

3. mikroBUS Socket

  • Location: At the bottom edge with a directional groove (anti-reverse insertion)
  • Functions:
    • Standard Compatibility: Supports mikroE Click series expansion boards (e.g., sensors, displays, communication modules).
    • Power Support: Provides 5V and 3.3V power pins to accommodate modules with different voltage requirements.

4. Qwiic Connector

  • Location: Middle of the right side, 4-pin polarized JST interface (anti-reverse insertion)
  • Functions:
    • Plug-and-Play: Enables quick connection to Qwiic ecosystem devices (e.g., SparkFun, Adafruit sensors) via the I2C protocol.

Tech Tips

  1. I2C Signal Sharing:
  • The mikroBUS and Qwiic connectors share the I2C bus (PB04/PB05 and PC04/PC05). Do not connect I2C devices to both simultaneously to avoid bus conflicts.
  1. Power Compatibility:
  • The 5V pin is directly sourced from USB, suitable for high-voltage peripherals.
  • The 3.3V (VMCU) pin is for low-voltage modules to prevent overvoltage damage.
  1. Directional Alignment:
  • Ensure the groove aligns when inserting mikroBUS or Qwiic devices to avoid reverse pin insertion.
