The DC_DC12/5cccv is a DC-DC step-down (buck) converter manufactured by LOWES with the part ID 46789. This component is designed to efficiently convert a 12V DC input to a stable 5V DC output, making it ideal for powering low-voltage devices such as microcontrollers, sensors, and other electronic modules from a higher voltage source. Its compact design and high efficiency make it a popular choice for embedded systems, automotive applications, and portable electronics.
This circuit consists of a DC-DC converter powering a 6-channel power module, which in turn supplies 5V to a 2-relay module. The power module distributes the converted voltage to the relay module, enabling it to control external devices.

This circuit appears to be a power supply unit with a bridge rectifier connected to a DC gear motor, indicating it is designed to convert AC to DC power for the motor. An electrolytic capacitor is used for smoothing the DC output, and a 7805 voltage regulator is included to provide a stable 5V output. Additionally, there is an LED with a series resistor, likely serving as a power indicator light.

The DC_DC12/5cccv module typically has four pins for input and output connections. The table below describes each pin:
| Pin Number | Pin Name | Description |
|---|---|---|
| 1 | VIN+ | Positive input voltage (8V to 14V) |
| 2 | VIN- | Negative input voltage (ground) |
| 3 | VOUT+ | Positive output voltage (5V) |
| 4 | VOUT- | Negative output voltage (ground) |
The DC_DC12/5cccv can be used to power an Arduino UNO from a 12V battery. Below is an example circuit and Arduino code:
// Example code to blink an LED connected to pin 13 of the Arduino UNO
// Ensure the Arduino is powered via the DC_DC12/5cccv module
void setup() {
pinMode(13, OUTPUT); // Set pin 13 as an output
}
void loop() {
digitalWrite(13, HIGH); // Turn the LED on
delay(1000); // Wait for 1 second
digitalWrite(13, LOW); // Turn the LED off
delay(1000); // Wait for 1 second
}

Module Not Working After Connection:
Q1: Can I use this module to power a Raspberry Pi?
A1: Yes, the module can power a Raspberry Pi as long as the total current draw does not exceed 3A.
Q2: Is the output voltage adjustable?
A2: No, the output voltage is fixed at 5V.
Q3: Can I use this module with a 24V input?
A3: No, the input voltage range is limited to 8V to 14V. Using a 24V input will damage the module.
Q4: Does the module have built-in short-circuit protection?
A4: Yes, the module includes basic short-circuit protection, but it is recommended to avoid intentional short circuits.
