The Neo 550 (technically called the NEO 550 Brushless Motor, often simply called a 550) is a brushless motor made by REV. The primary features of the 500 include the small footprint of the motor, taking up less size than previously available options.
Like the NEO Brushless V1.1 there is an integrated motor sensor (3-phase Hall Effect Sensors and a motor temperature sensor) in the 550, but it must use an either a Spark Max Motor Controller, or, with an adapter board, you can use the Spark Flex controller.
Team 4476 began using NEO 550 motors in 2020 2020 Robot Tanner, and they were also used on the 2022 robot 2022 Robot Leia and in 2023 Robot Misha and Zoey.
