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.
