Powering Aero Compute Board using external battery

Hello,

I would like to use the Aero Compute Board in a drone project that I am currently working on. My goal is to mount the compute board to the drone and have it send commands via MAVLink messages over WiFi. Since I am not using the standard drone included in the Ready to Fly Drone kit, I would like to use a dedicated external battery to power the compute board.

My question is - what type of external battery and power rating would be suitable for powering the compute board? Would the power + UART cable connector (included in the packaging) be a safe connector between an external battery with a 5.5mm male barrel plug? I am also open to alternative ideas, but I would like to avoid the need to disassemble the drone or interface with its hardware directly. Any insight is appreciated.

~Thanks

Hello ssavitz,

 

 

Thank you for your interest in the Intel Aero Compute Board.

 

In regards to your query, you can find answers in the following guide: https://www.intel.com/content/dam/support/us/en/documents/drones/development-drones/intel-aero-compu...

 

You can check out chapter 3 regarding Connectors.

 

 

Let me know if this helps?

 

 

Best regards,

Thank you for the responses.

Just to reiterate, I am trying to power just the compute board - not the drone. I would like to have the compute board and battery mounted onto my drone, so something weighing less than 0.5 lb is ideal. I also would like to know what the ideal rating for said battery would be ~ 3.3V, 5V? Amperage? Ideally, it could plug into the female barrel jack of the stock power + UART cable directly. I hope this clears up any confusion.

Can you tell me if the information provided on this thread was helpful for you?

 

Is there anything else I can assist you with?

Hi,

Because the compute board requires 5V at 3A, you would most definitely need a DC-DC converter if you want to power it by a battery. If I were you, I would get a 2S battery (7.4V) with at least 3A discharge rate (preferably a pre-made pack), and then covert that to 5V using a step-down converter like the one in the link below. The one in the link is a good, expensive one. You can buy DC-DC modules as cheap as 5 USD, but you'll be testing your luck with those.
