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 FrSky Neuron II 80 is an advanced Electronic Speed Controller (ESC) designed for various applications, building upon the performance and design features of the first-generation NEURON ESC products. This device offers a broader selection of ESC models to meet diverse demands.

Function Description:

The Neuron II 80 is primarily an ESC that controls the speed and direction of electric motors in remote-controlled models. It features a fully enclosed, all-CNC machined aluminum casing, which ensures efficient heat dissipation, allowing it to handle a continuous current of 80A. A key feature of the Neuron II series is its ability to transmit telemetry data from built-in sensors to the radio receiver. This provides users with real-time insights directly from their radio system, including RPM, power consumption, temperature, input/output voltage, and current readings.

The ESC supports the FBUS protocol, enhancing convenience by allowing users to easily configure the BEC (Battery Eliminator Circuit) output voltage and other ESC parameters directly from the transmitter via the receiver. For even greater flexibility, the Neuron II ESC can be connected to an ETHOS radio's S.Port for seamless wired configuration without needing a receiver (this feature is available on ETHOS 1.5.0 and later versions). The traditional configuration method through a PC webpage is also retained. The Neuron II 60/80 models support multiple signaling protocols, enabling them to drive and configure a wide range of compatible motors.

Maintenance Features:

• Firmware Upgrade: The firmware can be upgraded using an STK Tool (purchased separately) and a webpage configurator (https://gui.fettec.net/FrSky/ESC/). The process involves connecting the STK tool to a PC, selecting the "USB UART" port, connecting the NEURON2 ESC to the S.Port 2, switching the DIP to "Upgrade" mode, and then flashing the firmware.
• Over-Temperature and Over-Current Protection: Built-in safeguards to protect the ESC from damage due to excessive heat or current.

Warnings and Best Practices:

• Always read the manuals of all power devices and models before using the ESC to ensure rational power configuration and prevent overloading or damage.
• Keep the model away from unsafe elements like concrete buildings and high-voltage power lines to avoid damage and serious injuries.
• Always disconnect batteries from the ESC after use to prevent the motor from rotating unexpectedly and causing injuries. Prolonged connection can also fully discharge the battery, leading to malfunction of both the battery and the ESC.
