# NEO V1

## NEO V1 Overview

The REV NEO Brushless Motor (REV-21-1650) is the first brushless motor designed to meet the unique demands of the FRC community. Offering an incredible power to weight ratio along with it's compact size it's designed to be a drop-in replacement for CIM-style motors as well as an easy install with mounting options.

### Features

* Drop-in replacement for CIM-style motors
* Shielded out-runner construction
* Front and rear ball bearings
* High-temperature neodymium magnets
* High-flex silicone motor wires
* Integrated motor sensor
  * 3-phase hall sensors
  * Motor temperature sensor

## Wiring Connections

Connecting the NEO V1.1 Brushless motor is fairly straightforward. Follow the guide at[ Wiring the Spark Max](/brushless/spark-max/gs/wiring.md), and don't forget to connect your sensor wire; the motor will not spin without it!
