NEEBRC 3520 1850/2250KV Outrunner Brushless Motor AM32 Programming 80A ESC BEC for RC Crawler Car Axial Traxxas SCX10 TRX4 TRX6

ESC Description:
This ESC comes pre-installed with AM32 custom firmware. It is optimized for crawler vehicles, providing verysmooth and quiet operation of your crawler, but it is also suitable for various 1/8 scale or smaller cars. It features a built-in adjustable quad-group voltage BEC, with a maximum current of 10A, for high-torque servo applications. Additionally, the included e-Switch helps avoid failures caused by harsh environments. All wires are pre-soldered.

USB Link

For AM32/BL32, connects the ESC to a computer for configuration or firmware upgrade.
Portable and easy to use, simply connect the ESC signal plug, connect the USB Type-C cable to a computer, and install the VCP driver.
AM32 firmware is specifically designed for AT32 ARM processors, for controlling brushless motors (BLDC). The firmware is designed to be safe, fast, with a smooth and rapid start, and linear throttle. It is suitable for various vehicle types and flight controllers.

M32 features include:

● Firmware upgradeable via Betaflight pass-through, single-wire serial, or Arduino
● Servo PWM, Dshot (300,600) motor protocol support
● Bi-directional rotation
● KISS standard ESC telemetry
● Variable PWM frequency
● Sine start mode, designed to accelerate large motors

BEC Output Voltage Adjustment

Firmware Upgrade

1.Connect the ESC to the tuner, as shown in the diagram.Open the ESC Configuration Tool.

2.Check Direct Connect when using Arduino PC Link (do notcheck when using the flight controller interface).

3.Select your Arduino port.

4.Click the "Connect" button.

5.Read the ESC settings using the M1 button.Now, you can adjust settings, change tabs, upload new firmware, or load the default
eeprom settings.

6.After making adjustments, save your settings.To carefully check if your settings have been applied, close the connection, then reconnect and press M1 again.

7.

8.First,check the appropriate box. Second, select the serial port number where the tuner is located. Third, connect the motor to the ESC.

9.Choose and download the firmware needed for the direct upgrade.

Parameter

Pay special attention to a few points here:

1.If using a 6S lithium battery, do not set the sine power value to 10, as this will cause both the motor and the ESC to become very hot.

2.When using 3-4S lithium batteries, set the sine power value based on the direct weight of the vehicle, usually around 6-8 is appropriate.

For 3S-4S batteries, the recommended parameters are(set the motor KV value and the number of poles according to your motor’s specifications)

For 6S batteries, the recommended parameters are (set the motor KV value and the number of poles according to your motor’s specifications)

Warning:

1.If using a 6S lithium battery,do not set the sine power value to 10, as this will cause both the motor and the ESC to become very hot.

2.When using 3-4S lithium batteries, set the sine power value based on the direct weight of the vehicle, usually around 6-8 is appropriate.
