This manual provides essential information for the safe and effective use of your DROK Mini DC-DC Buck Converter module. Please read these instructions thoroughly before installation and operation to ensure optimal performance and prevent damage.
2. Alaye Aabo
- Rii daju igbewọle voltage does not exceed the specified maximum of 24V DC.
- Observe correct polarity when connecting input and output wires. Incorrect connections can damage the module and connected devices.
- Do not exceed the maximum output current of 3A. For continuous operation at or near 3A, additional cooling may be required to prevent overheating.
- Handle the module with care to avoid electrostatic discharge, which can damage sensitive electronic components.
- Keep the module away from moisture and extreme temperatures.
3. Ọja Ipariview
The DROK Mini DC-DC Buck Converter is a compact voltage reducer designed to step down a DC input voltage to a lower, stable DC output voltage. It features both adjustable and fixed output voltage options, making it versatile for various electronic projects.

- Output +: Positive terminal for the regulated output voltage.
- Common negative: Ground connection for both input and output.
- Input +: Positive terminal for the input DC voltage (4.5V to 24V).
- Enable port (EN): Controls the module's operation. Defaults to working mode. Connecting to a low electrical level (e.g., ground) will turn the module off.
- Iwọn agbara: A lo lati ṣatunṣe iwọn didun iṣẹjadetage when in adjustable mode.

Connect your input power source to the Iṣawọle + ati Common negative (GND) terminals. Connect your load to the Ijade + ati Common negative (GND) terminals. Ensure all connections are secure and observe correct polarity.
5.2. O wujade Voltage Atunṣe
The module offers two methods for setting the output voltage:
Adijositabulu o wu Voltage:
By default, the module is in adjustable mode. Use a small screwdriver to turn the agbara (refer to Image 1) to set the desired output voltage between 0.8V and 17V. It is recommended to monitor the output voltage pẹlu kan multimeter nigba tolesese.
Ti o wa titi Abajade Voltage:
To use a fixed output voltage (1.8V, 2.5V, 3.3V, 5V, 9V, 12V), you must modify the module by soldering. This involves cutting a specific trace and then soldering a jumper to the desired voltage pad on the back of the board.
- Locate the 'ADJ' pad on the back of the module.
- Carefully cut the trace connecting the 'ADJ' pad to the rest of the circuit (as indicated in Image 2).
- Solder a jumper wire or bridge the solder pad corresponding to your desired fixed voltage (e.g., 5V, 3.3V) to the adjacent common pad.
5.3. Enable Port (EN) Usage
Awọn ese Enable port (EN) defaults to working mode. To turn the module off, connect the EN pin to a low electrical level (e.g., ground). This feature provides convenient control over the module's power state.
6. Awọn ilana Iṣiṣẹ
Once properly wired and configured, apply the DC input voltage. The module will convert it to the set output voltage. Always ensure your load's current draw does not exceed the module's capacity, especially without additional cooling.
