# SPARK Flex Feature Description
The SPARK Flex Motor Controller is a fully featured smart motor controller designed to be robust and easy to use yet fully capable of advanced motion control. The following sections describe each feature in detail.
### SPARK Flex Connections
#### [USB-C Port ](/brushless/spark-flex/spark-flex-feature-description/control-connections.md#usb-c-port)
Allows for seamless firmware updates and code uploads, facilitating quick and efficient software management through the REV Hardware Client
#### [Locking Data Port ](/brushless/spark-flex/spark-flex-feature-description/data-port.md)
Allows for integration of additional sensors such as the Through Bore Encoder, analog sensors, absolute encoders, and limit switches.
#### Ultra-flexible, and Silicone-coated Wires
Supply [Input Power](/brushless/spark-flex/spark-flex-feature-description/power-and-motor-connections.md) and [Control Signals](/brushless/spark-flex/spark-flex-feature-description/control-connections.md) through 45cm long high-quality wires. Twisted Control wires also feature [two standardized connectors](/brushless/spark-flex/spark-flex-feature-description/control-connections.md#can-pwm-connections) to make wiring the SPARK Flex easy for PWM or CAN control.
