Power supply

WARNING - Do not exceed the maximum input voltage

Exceeding the maximum input voltage of 100 V may result in permanent damage to the device. Ensure that the input voltage remains within the specified limits at all times. Special care has to be taken if voltage transients and oscillations are present, as these may cause the maximum rating to be exceeded. This can occur in systems with high inductance, during switching events, or when using motor controllers with active braking. Appropriate suppression and protection measures must be implemented.

WARNING - Beware of excess heat

Heat is generated by all onboard voltage regulators during operation, with dissipation increasing at higher load current and total power consumption. Adequate thermal management, such as airflow or passive cooling, is recommended when operating the board at higher load conditions to ensure proper thermal performance and prevent overheating. Onboard power monitoring can be used to provide a precise overview of power consumption across the whole system.

Recommended Input Voltage Range: 20–80 V

Maximum Input Voltage: 100 V

Onboard supply rails

GIMBAL_PWR

Output voltage: 18.2V

CAM0 (4-lane CSI)

• 501951-2210 connector type

• 4 lanes MIPI CSI connectors

• I2C and PWDN are 3V3 logic

WARNING

Pay attention to the orientation of the cable pins (same/opposite side contacts). Cameras from different manufacturers can have different pin orders, so using the wrong cable can cause a short circuit.

Note:

CAM_SUPPLY is configurable to 3V3 or 5V by solder bridges on the top side of the board SB1 open = 3V3 , SB1 closed = 5V SB2 open = 3V3 LDO on , SB2 closed = 3V3 LDO off
