ASUS Tinker Board Is An Interesting ARM SBC For About $60 USD

[azdaha]

This thing will draw 2.3A. The review should mention that 90%+ of the power supplies on the market will not deliver enough current and cause brown outs with this board. They are drawing unacceptable amounts of current on the order of 30% over the MicroUSB connector design spec. Otherwise this board is great except for the lack of ARMv8. You have to use our custom designed power supplies to keep the voltages on the 5V rail over 4.75V.

I bought this a couple of months ago. I don't think it came with a power-supply . If that's the case, it might explain some interesting issues regarding its stability.
