3. Key Features
- Compatible Models: Designed for boards (5V or 3.3V) with 0.1 inch (2.54 mm) pin spacing, widths of 0.6, 0.7, 0.8, 0.9, 1.0 inch, and lengths up to 2.3 inch (24 pins). This includes Arduino Nano/Micro, Raspberry Pi Pico 1/2 (W), ESP32, and ESP8266.
- Power Supply Options: Can provide 5V and 3.3V power (up to 3A via DC-DC circuit) when using a 6-24V DC input. Alternatively, it can utilize power from the main board. Jumper caps must be configured according to the tutorial for proper power selection.
- GPIO Status LED: Each GPIO pin features an LED indicator. The LED illuminates when the GPIO outputs or inputs a high logic level and turns off for a low logic level.
- Independent LED Drive: The status LEDs are driven by a dedicated chip, ensuring that the LEDs do not draw current directly from the GPIO pins and thus do not affect the performance or signal integrity of your microcontroller.
- Terminal Block and Header: Provides both screw terminal blocks and pin headers for connecting to all pins of the main board, with a 2.54 mm (0.1 inch) pitch.

5. Setup Instructions
5.1. Board Installation
Carefully align the pins of your compatible microcontroller board (e.g., Arduino Nano, Raspberry Pi Pico, ESP32) with the central pin headers on the FREENOVE Universal Breakout Board. Gently press down until the board is securely seated. Ensure all pins are correctly aligned to prevent damage.
5.2. Power Configuration
The breakout board offers flexible power options. You can either power it externally or use the power from your main microcontroller board.
5.2.1. External Power Supply
For external power, connect a DC power source (6-24V) to the DC jack on the breakout board. This configuration allows the board to provide up to 3A of 5V and 3.3V power to connected components. Ensure the jumper caps are set to enable external power, as detailed in the comprehensive tutorial available for download.
5.2.2. Main Board Power
If you prefer to use the power from your main microcontroller board, configure the jumper caps accordingly. Refer to the downloadable tutorial for specific jumper settings to ensure correct operation and prevent power conflicts.

6. Operating Instructions
6.1. Connecting Components
Use the provided screw terminal blocks or pin headers to connect your external sensors, actuators, or other electronic components to the GPIO pins of your microcontroller. The 2.54 mm (0.1 inch) pitch ensures compatibility with standard jumper wires and breadboards.
6.2. Monitoring GPIO Status
The breakout board features individual LED indicators for each GPIO pin. These LEDs provide real-time visual feedback on the logic level of each pin:
- LED On: Indicates that the GPIO pin is outputting or inputting a high logic level (e.g., 5V or 3.3V).
- LED Off: Indicates that the GPIO pin is outputting or inputting a low logic level (e.g., 0V or Ground).

6.3. Independent LED Functionality
The status LEDs are designed to operate independently of the GPIO pins. They are driven by a dedicated NOT gate chip, ensuring that the LEDs do not draw current directly from the GPIO pins and thus do not affect the performance or signal integrity of your microcontroller.

8. Troubleshooting
8.1. No Power to Components
- Check Jumper Caps: Ensure that the power selection jumper caps are correctly configured for either external power or main board power. Refer to the tutorial for the correct settings.
- Verify External Power Source: If using external power, confirm that the DC power source is connected and providing the correct voltage (6-24V).
- Inspect Main Board Power: If using main board power, ensure your microcontroller is powered on and supplying sufficient voltage and current.
8.2. GPIO LEDs Not Functioning
- Check Connections: Verify that your microcontroller is correctly seated on the breakout board and that the GPIO pins are making proper contact.
- Test GPIO Output: Confirm that the GPIO pins on your microcontroller are actually changing state (high/low) as expected through your code or a multimeter.
- Power Supply: Ensure the breakout board is receiving power, as the LEDs require power to operate, even if driven independently.
8.3. Board Not Fitting
- Verify Dimensions: Double-check that your microcontroller board's pin spacing, width, and length match the compatible dimensions specified in Section 1. Product Overview.
- Pin Alignment: Ensure that the pins are perfectly aligned with the headers before applying pressure. Misalignment can bend or damage pins.
9. Maintenance
- Cleaning: Keep the board clean and free from dust and debris. Use a soft, dry brush or compressed air to remove any accumulation.
- Storage: Store the breakout board in a dry, anti-static environment when not in use to prevent damage from static discharge or moisture.
- Handling: Always handle the board by its edges to avoid touching the electronic components, which can be sensitive to static electricity or oils from your skin.
