Most capable -vs- lowest current draw

Post by L67GS » Sun May 10, 2020 1:12 am

I'm considering an embedded robotics application that would require the SBC to run on battery power for hours on end. It would need IO ports, and need to run Linux headless.

I think the Odroid-CO is the correct SBC for the job, unless there's another lower current draw Odroid that I could just run the IO USB adapter in but wiringPi looks easier to use than that thing.

Any input from those who have more familiarity?

The C0 is what you likely want, just add a lipo and it's ready to go. Built in charging and battery monitoring.

I'm hoping Hardkernel will do a low power device like the C0 based on the Odroid Go Advance hardware in the future.

Thank you, I thought the CO would be it, any idea of average power consumption? Of course it varies based on peripherals and load but maybe how long it will run on the battery that Ameridroid sells?

Here are my own figures.
C0 Ubuntu Minimal headless with latest OS updates, BUT with USB DAC attached, an 8-segment LED display and an additional LED.
Performance governor, CPU @ 1.3 GHz.
Sorry, this was the setup I needed to test, I know it's not stock but consider no more than 25 mA between display and LED, maybe 30-40mA for DAC.

While booting: up to 440mA
Idle: 260mA
Heavy load (large parallel build): 500mA
Power off: 60mA

All in all, an excellent board as power draw vs. performances.

Me too would LOVE a newer board with even lower power draw (Rockchip RK3326 maybe?) !!
Please!!

Whoa! Half of an amp max with a USB device plugged in! That's incredibly efficient, thank you for sharing your numbers.

You're welcome.
It's a nice little critter, the C0. Power draw just a bit higher than RPI Zero, but way, way faster.

For your project, you may also have a look at the Odroid GO Advance "Board Only", when it will be available again (out of stock now).
Awkward shape (it is designed for a portable console) but should be very power efficient (ARM Cortex A-35 quadcore).

I think I'm just going to order a CO when Ameridroid gets the port kits in for it. It's so powerful that this application should never outgrow it, my plan is to use an inductive charger to charge one of those USB power brick things and a small regulator circuit.
I've never used vnc before so for now I'm figuring everything out on my XU4. And then when the CO project comes I won't have to work my way through vnc and other things.
I don't like the off/on switch, momentary like the XU4 would be better for me but I can work with it.

Note that C0/C1 and C2 might get discontinued next year, so don't plan long-term deployments/new products based on them.

Just personal use, will HK be releasing a replacement for the C series?

C1/C2 can be replaced by C4. C0 doesn't have a replacement. But I expect they have C0 stocks for the following year
