How to Use Wireless charging module transmitter CC1: Examples, Pinouts, and Specs

The Wireless Charging Module Transmitter CC1 is a device designed to transmit power wirelessly to compatible receivers using electromagnetic induction. This module eliminates the need for physical connectors, enabling convenient and efficient charging for a variety of devices. It is commonly used in applications such as wireless phone chargers, wearable device chargers, and other consumer electronics requiring contactless power transfer.

• Wireless charging pads for smartphones and tablets
• Charging stations for wearable devices (e.g., smartwatches, fitness trackers)
• Embedded wireless charging solutions in furniture or vehicles
• Prototyping and development of wireless power transfer systems

1. Power Supply Connection:

   • Connect the VCC pin to a stable 5V DC power source.
   • Connect the GND pin to the ground of the power source.

2. Coil Connection:

   • Attach the wireless transmission coil to the OUT+ and OUT- pins. Ensure proper polarity.

3. Placement:

   • Place the compatible wireless receiver device (e.g., a smartphone or receiver module) within the effective charging range (typically 2-8mm) of the transmission coil.

4. Operation:

   • Once powered, the module will generate an electromagnetic field to transfer power wirelessly to the receiver.

• Ensure the input voltage does not exceed 5V to avoid damaging the module.
• Use a high-quality power source to maintain stable operation.
• Avoid placing metal objects between the transmitter and receiver, as they can interfere with power transfer.
• Maintain proper alignment between the transmitter coil and receiver coil for optimal efficiency.

While the CC1 module does not directly interface with an Arduino, you can use an Arduino to control the power supply to the module. Below is an example of how to toggle the power to the module using a relay:

// Example: Controlling the Wireless Charging Module with Arduino
// This code toggles the power to the CC1 module using a relay module.

const int relayPin = 7; // Pin connected to the relay module

void setup() {
  pinMode(relayPin, OUTPUT); // Set relay pin as output
  digitalWrite(relayPin, LOW); // Ensure relay is off at startup
}

void loop() {
  digitalWrite(relayPin, HIGH); // Turn on the relay (power to CC1)
  delay(10000); // Keep the module on for 10 seconds
  digitalWrite(relayPin, LOW); // Turn off the relay (cut power to CC1)
  delay(5000); // Wait for 5 seconds before turning it on again
}

Note: Ensure the relay module is rated for the input voltage and current of the CC1 module.

1. No Power Transmission:

   • Cause: Incorrect power supply connection.
   • Solution: Verify that the VCC and GND pins are properly connected to a 5V DC power source.

2. Low Charging Efficiency:

   • Cause: Misalignment between the transmitter and receiver coils.
   • Solution: Adjust the placement of the receiver device to ensure proper alignment.

3. Overheating:

   • Cause: Prolonged operation at maximum load or poor ventilation.
   • Solution: Ensure adequate airflow around the module and avoid exceeding the rated power.

4. Interference with Other Devices:

   • Cause: Electromagnetic interference from the module.
   • Solution: Maintain a safe distance between the module and sensitive electronic devices.

• Q: Can the CC1 module charge devices with higher power requirements?
  A: No, the CC1 module is limited to a maximum output power of 5W. For higher power requirements, consider using a higher-rated wireless charging module.

• Q: What is the effective charging range of the CC1 module?
  A: The effective range is typically 2-8mm, depending on the receiver device and coil alignment.

• Q: Can I use the CC1 module outdoors?
  A: The module is not weatherproof. If outdoor use is required, ensure it is enclosed in a waterproof and heat-resistant casing.

• Q: Is the CC1 module compatible with Qi wireless charging standards?
  A: The CC1 module is not explicitly Qi-certified but may work with some Qi-compatible devices. Testing is recommended for specific use cases.
