Introduction
Based on the performance and design features of the first-gen NEURON ESC products, the NEURON II line
steps it up by offering a broader selection of ESC models to various demands in different applications.
The NEURON II 80 comes with a fully enclosed all-CNC machined aluminum casing design, ensuring efficient
heat dissipation while handling a continuous current of 80A. The NEURON II series can transmit telemetry data
from built-in sensors to the radio by the receiver, allowing users to get real-time insights right from the radio
system. RPM, power consumption, temperature, input/output voltage, and current readings are all at your
fingertips.
With added support for the FBUS protocol, the NEURON II takes convenience to a whole new level! Users can
now easily configure the BEC output voltage and other ESC parameters directly from the transmitter via the
receiver. Or with even more flexibility, hook up NEURON II ESC to the ETHOS radio’s S.Port for seamless wired
configuration without requiring a receiver (this feature will be available on ETHOS 1.5.0 and later versions). The
traditional configuration method through a PC webpage is also retained. There’s more! The NEURON II 60/80
comes with support for multiple signaling protocols which can be used to drive and configure a wide range of
compatible motors.

The configuration methods provided below are for reference only. Due to firmware updates or other reasons, the
functionality description may vary. Please refer to the latest official user manual for accurate configuration
instructions.
Here are the descriptions of various features on the web-based ESC configuration page of FrSky Neuron II.
1. Reverse motor direction: This feature allows you to control whether the motor spins in the opposite direction.
Checking this option will reverse the motor direction.
2. Slow start: It controls the gradual acceleration of the motor during startup to avoid sudden and strong reactions.
3. Soft start: This feature enables a smooth acceleration of the motor during startup, reducing the impact force
and load on the motor.
4. ESC beeps: It determines whether the ESC emits audible beeps during startup, serving as an indicator of its
status.
5. PWM Min: This setting determines the minimum PWM signal value that the ESC will recognize as the lowest
throttle position.
6. PWM Max: It sets the maximum PWM signal value that the ESC will recognize as the full throttle position.
7. Soft brake: This feature controls whether the ESC implements a smooth braking action when transitioning to
low throttle.
8. 3D Mode: It activates a special mode in the ESC suitable for performing aerobatic maneuvers and 3D flight
actions.
Note: To configure the Neuron II ESC, please connect the STK tool to your computer and connect the
power supply to the Neuron II ESC.

9. Current calibration(%): This option allows you to calibrate the ESC to accurately measure current, providing
precise current data.
10. Current limit: It lets you set the maximum current output limit of the ESC to protect both the ESC and the motor
from overloading.
11. BEC output Voltage: You can specify the output voltage of the ESC's built-in BEC (Battery Eliminator Circuit).
12. Activated: Display ESC Activation Status.
13. Trapeziodal commutation
14. Physical ID: This setting specifies the physical ID used for communication.
15. Application ID: This setting specifies the Sensor ID used for communication.
16. Response Time(*100ms): It determines the time gap between communications.
17. High demag. protection
18. Motor pole count: It refers to the number of magnetic poles inside the motor. You need to set the correct pole
count to ensure proper motor rotation and ESC commutation.
19. Throttle channel: Specify the serial port signal channel for the throttle channel input signal used to control the
ESC, such as SBUS/FBUS.
20. OneWire ID: This feature assigns a unique ID to each ESC when using OneWire bus communication.
These features offer a wide range of configuration options to meet the requirements of different types of aircraft
and flight preferences. Specific features and options may vary based on the version of FETtec Configurator and
device support. Please consult the relevant documentation or official guides for more detailed information before
using these options.

● Always keep your model away from unsafe elements, such as concrete buildings and high-voltage power lines.
Fly your models according to the manual strictly, or it may cause damage and serious injuries.
● Always disconnect the batteries from the ESC after use, or it may drive the motor to rotate and cause injuries.
If the ESC is connected to the battery for a long time, the battery will be fully discharged, which may lead to the
malfunction of both batteries and the ESC.
