The For CAN Hub is a powered CAN port expansion module developed for 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 and can a stable 5V power source to your CAN peripherals. Input voltage:2S - 12S Output voltage:5.2V0.15V Max current output:1.0A @ 5.2V per CAN port. The total current of the 4 ports cannot exceed 3A.
