Design with iFlight BLITZ BEC 5v/12v in Cirkit DesignerThe iFlight BLITZ BEC 5V/12V is a compact and efficient Battery Eliminator Circuit (BEC) designed to provide a stable output voltage of either 5V or 12V. This component is widely used in remote control (RC) applications, such as drones, airplanes, and cars, to power servos, receivers, flight controllers, and other onboard electronics directly from a LiPo battery. By regulating the battery's voltage, the BEC ensures reliable operation of sensitive electronics while protecting them from voltage fluctuations.
This circuit is designed for a quadcopter, featuring four BLDC motors each controlled by an Electronic Speed Controller (ESC). The ESCs are powered by a LiPo battery through a power module, and the system is managed by an APM 2.0 flight controller, which also interfaces with a GPS module, an RC receiver, and telemetry for communication.

This circuit is designed for a multi-motor application, likely a drone or a similar vehicle, featuring eight brushless motors controlled by two 4-in-1 electronic speed controllers (ESCs). The ESCs are powered by a 3s2p 18650 battery pack and interfaced with a Pixhawk flight controller for motor management. Additionally, the system includes a Raspberry Pi 4B for advanced processing and control, which is connected to a NoIR camera module and a cooling fan, and a power module to supply and monitor the power to the Pixhawk.

Power On the Circuit:
The iFlight BLITZ BEC can be used to power an Arduino UNO from a LiPo battery. Below is an example setup:
Here is a simple Arduino code example to blink an LED while powered by the BEC:
// Blink an LED connected to pin 13 of the Arduino UNO
// Ensure the BEC is providing 5V to the Arduino's 5V pin
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
}
No Output Voltage:
Cause: Incorrect SEL pin configuration.
Solution: Verify the SEL pin is correctly set to 5V or 12V.
Cause: Loose or incorrect connections.
Solution: Check all connections, ensuring VIN and GND are properly connected to the battery.
Overheating:
Output Voltage Fluctuations:
Connected Device Not Powering On:
Q: Can I use the BEC to power multiple devices simultaneously?
A: Yes, as long as the total current draw does not exceed 3A.
Q: How do I switch between 5V and 12V output?
A: Use the SEL pin to configure the output voltage. Refer to the pin configuration table for details.
Q: Is the BEC compatible with 1S LiPo batteries?
A: No, the minimum input voltage is 7V, which is higher than the voltage of a 1S LiPo battery.
Q: Can I use the BEC with non-LiPo power sources?
A: Yes, as long as the input voltage is within the 7V to 26V range.
