Key Components & Their Functions:
- DC JACK for 12V DC Input:
- This barrel jack connector is used to supply 12V DC input to the board.
- Ensure you connect a regulated 12V power adapter for proper functioning.
- DC IN/OUT Pin Header:
- This set of pins allows 12V DC to be supplied or taken out.
- You can use this if you want to power another device with 12V from this board.
- GND Pins (Ground):
- Multiple GND (Ground) pins are provided for common grounding.
- Always connect the GND pin while using 3.3V or 5V outputs.
- 3.3V OUT Pin Header:
- This pin provides a regulated 3.3V output.
- Useful for powering microcontrollers like ESP8266, ESP32, or low-voltage sensors.
- 5V OUT Pin Header:
- This pin provides a regulated 5V output.
- Suitable for powering Arduino, sensors, motors, or other 5V devices.
- Voltage Regulator ICs (likely AMS1117):
- These ICs convert 12V input into stable 3.3V and 5V outputs.
- The heat dissipation may occur, so ensure proper ventilation.
- Blue Push Button (Reset or Power Control Switch):
- This switch is typically used for power control or reset functionality.
- If pressing this button cuts off power, it acts as an ON/OFF switch.
How to Use This Board:
- Powering the Board:
- Plug a 12V DC adapter into the DC JACK.
- Alternatively, you can supply 12V through the DC IN/OUT pins.
- Using the Voltage Outputs:
- Connect GND to the common ground of your circuit.
- Use 3.3V OUT for low-voltage components (ESP8266, sensors).
- Use 5V OUT for Arduino, relays, or modules requiring 5V.
- Safety Tips:
- Do not exceed 12V input, as it may damage the voltage regulators.
- Ensure proper heat dissipation, as the regulators may get hot.
- Avoid short circuits between GND, 3.3V, and 5V pins.
Note: This module is ideal for powering microcontrollers, sensors, and small electronics projects that need stable 3.3V or 5V power from a 12V supply.
