Product size

• Size: 229mm*191.98mm * 85.94mm (including bracket)
• Weight: 1600 ± 50g

 Installation requirements

• The BT/WIFI antenna side needs to maintain a distance of at least 50mm from the metal parts of the car body.
• The connector side needs to have at least 50mm of operating space for wire harness bending.
• To ensure the heat dissipation path, please ensure a natural convection space of at least 35mm on both sides of the host. When the conditions cannot be met, please reserve a convection vent.
• In order to ensure the effect of heat dissipation fins, the angle between the Z’axis of the car system and the positive direction of the Z-axis of the car body should not exceed ± 90 °.
• The size of the host’s heat dissipation hole is 2.6mm, and it has openings on three sides, which cannot prevent splashing. It is recommended to stay away from the air conditioning duct
