The Sequoia contains a lot of technology and can get hot when switched on and capturing. This is normal, as Sequoia was primarily designed to be integrated on a drone and cooled down during a flight.
When integrated on on a drone, the integration should be made to facilitate airflow on the back heat sink so the Sequoia can be cooled down during the flight.
If running in timer mode on the ground, ensure that you use a fan to provide adequate airflow to the back of the Sequoia. If placed on a desk, the Sequoia should be placed vertically on its edge and not on the back heat sink.
If integrated on a different platform (such as a tractor, robot, or mower), ensure proper airflow using a small cooling fan.
