# Sensors on the platform

> Sensor parts and connectivity configurations available on the Dragonwing RB3 Gen 2 Development Kit.

The following table lists the Core Kit sensors supported on the Qualcomm Dragonwing™ RB3 Gen 2 Development Kit. For more information about the Core Kit, see [Qualcomm Dragonwing™ RB3 Gen 2 Development Kit Quick Start](https://docs.qualcomm.com/doc/80-80023-253).

**Table : Core Kit sensors**

| Placement  | Sensor part | Sensor type                 |
| ---------- | ----------- | --------------------------- |
| Main board | ICM42688    | Accelerometer and gyroscope |

Only one accelerometer and gyroscope sensor part can be enabled on the Vision Kit at a time. The following table lists the Vision Kit sensors supported on the Qualcomm Dragonwing™ RB3 Gen 2 Development Kit. For more information about the Vision Kit, see [Qualcomm Dragonwing™ RB3 Gen 2 Development Kit Quick Start](https://docs.qualcomm.com/doc/80-80023-253).
