The SPARK Flex (REV-11-2159) is a new smart motor controller from REV Robotics. Its dockable form factor allows for direct mounting onto a NEO Vortex (REV-21-1652), simplifying wiring while maintaining flexibility. Improving upon the foundation of the SPARK MAX, new features include 3-phase current sensing, reverse polarity protection, and an expanded Data Port with additional interfaces. When docked to an adapter, the SPARK Flex can control any existing NEO or compatible brushless/brushed DC motor.

Feature Highlights:

• Docking interface for motor phases and sensors

• USB type C configuration and control

• PWM and CAN communication

• Fully integrated power and control wires

• Enhanced data port with more power, latching connector, and additional serial interfaces

• Advanced motor control modes include:

  • Velocity

  • Position

  • Current

  • New modes with future firmware updates

• #10-32 threaded holes on a 2in bolt circle

• Motor and motor controller's silhouette fits behind a standard 2in rectangular tube

Flex Dock Overview

The Flex Dock transforms the SPARK Flex (REV-11-2159) into a standalone motor controller, supporting REV brushless motors and virtually any 12V brushed DC motor by providing standard phase wire outputs. The 6-pin JST PH encoder port is compatible with NEO/NEO550 hall sensors in brushless mode and standard quadrature encoders in brushed mode.

The dock securely mounts to a SPARK Flex using the same docking hardware as if you were mounting to a NEO Vortex. It features five #10-32 threaded mounting holes on a 0.5-inch grid, enabling versatile mounting on either face of the combined stack.

Additionally, the Flex Dock offers added protection against common faults caused by damaged motors or wiring. Compact and lightweight, it empowers you to adapt a SPARK Flex to meet your specific motor control requirements.

Flex Dock Features
