- Magnet Type: Neodymium, 8-pole
- Cable Length: 150mm with 3-pin female servo header
Package Contents
- 2× Neodymium 8-pole magnets with rubber hubs
- 2× Hall-effect sensors with cables and servo headers
Ideal For
- Measuring wheel speed and distance on robot chassis
- Odometry and closed-loop motor control
- RedBot and multi-chassis robot platforms
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
