The Holybro CAN Hub is a powered CAN port expansion module developed for various flight controllers and their supporting peripherals. This CAN Hub is integrated with a step-down power supply. It supports 2-12S power input and 5V CAN power output and can expand one CAN port into up to four ports while providing stable 5V/1A power for each port with its dedicated power input.

Most flight controllers have a 5v output on the CAN port, but the voltage can sometime be lower than 5v because it is affected by other devices that is connected to the FC, and there is a ~3A current limit for sum of all ports (Excluding Telem1). The power supply of this hub is independent and can guarantee a stable 5V power source to your CAN peripherals.

Technical Specification:

• Input voltage: 2S - 12S
• Output voltage: 5.2V±0.15V
• Max current output: 1.0A @ 5.2V per CAN port. The total current of the 4 ports cannot exceed 3A.
• Power-In Connector: XT30
• CAN in Connector: GHR-4V-S
• CAN Out Connector: 4 Port BM04B-GHS-TBT
