Pin Configuration

40 AMP ESC - Yellow Component Documentation
Pinout Explanation:
The 40 AMP ESC - Yellow has a total of 12 pins, which are used to control and power the Electronic Speed Controller (ESC) of a brushless motor. Here is a detailed explanation of each pin and its function:
Signal Pins:
1. S1 (Signal 1): This pin is the throttle signal input from the flight controller or transmitter. It receives a PWM (Pulse Width Modulation) signal to control the motor speed.
2. S2 (Signal 2): This pin is an optional signal input for advanced features such as telemetry or custom protocols.
Power Pins:
3. B+ (Battery Positive): This pin connects to the positive terminal of the battery.
4. B- (Battery Negative): This pin connects to the negative terminal of the battery.
Motor Pins:
5. M1 (Motor Wire 1): This pin connects to one of the three motor wires ( typically yellow, blue, or orange).
6. M2 (Motor Wire 2): This pin connects to another motor wire (typically yellow, blue, or orange).
7. M3 (Motor Wire 3): This pin connects to the remaining motor wire (typically yellow, blue, or orange).
Sensor Pins:
8. VCC (Voltage Regulator Output): This pin provides a 5V output for powering sensors, such as current sensors or voltage sensors.
9. GND (Ground): This pin is the ground reference for the ESC and connects to the negative terminal of the battery.
10. Curr (Current Sense): This pin connects to a current sensor to monitor the motor current.
Telemetry Pins:
11. TX (Transmit): This pin transmits telemetry data from the ESC to the flight controller or a telemetry module.
12. RX (Receive): This pin receives telemetry data from the flight controller or a telemetry module.
Connection Guide:
To connect the pins, follow these steps:
Step 1: Connect the battery
Connect the positive terminal of the battery to the B+ pin.
Connect the negative terminal of the battery to the B- pin.
Step 2: Connect the motor
Connect one motor wire to the M1 pin.
Connect another motor wire to the M2 pin.
Connect the remaining motor wire to the M3 pin.
Step 3: Connect the signal
Connect the throttle signal wire from the flight controller or transmitter to the S1 pin.
Step 4: Connect sensors (optional)
If using a current sensor, connect the sensor output to the Curr pin.
If using a voltage sensor, connect the sensor output to the VCC pin.
Step 5: Connect telemetry (optional)
If using telemetry, connect the TX pin of the ESC to the RX pin of the telemetry module or flight controller.
If using telemetry, connect the RX pin of the ESC to the TX pin of the telemetry module or flight controller.
Important Notes:
Make sure to connect the motor wires in the correct sequence ( typically: yellow to M1, blue to M2, and orange to M3).
Ensure the battery voltage is within the specified range for the ESC.
Consult the user manual and documentation for specific connection diagrams and configurations.
Remember to handle the ESC with care, as it is a sensitive electronic component. Incorrect connections or improper use can damage the ESC or cause harm to the user.
