Im beeing having some problems with the cube (The GPS goes Off on the air and GPS compass problems), and I have just realize the problem starts when I use 2 distance sensors connected to the BlackCube. Im using the TFMini sensor:
You’d be best served powering your peripherals from another source like a BEC as opposed to drawing the power from the Cube/Carrier board. There have been many users who have been struggling with this. The solution is to power your extra gear from elsewhere.
To answer your question…it depends on which port you are plugged into.
Peripheral power is split into two groups:
• Serial 1 has a private 1.5A current limit, intended for powering a telemetry radio.
This output is separately EMI filtered and draws directly from the USB / Brick inputs.
Peak power draw on this port should not exceed 2A, which should be sufficient for a
30dBm transmitter of reasonable efficiency.
• All other peripherals share a 1A current limit and a single power switch. Peak
power draw on this port should not exceed 1.5A.
…so…outside of the Serial 1 port (Which you are likely using for Telem); ALL other peripherals SHARE 1A TOTAL.
