First of all, congrats for a very interesting product.
THe board looks very good from a specs. point of view, but what about the power consumption?
How much power does it need in idle and how much power does consume under full load?

Hi guys,
i require your helps and ideas.
i run openssl speed rsa to evaluate the power of my PINE64+ board (i am a crypto guy).
i was a litle bit surprised to see big difference using different distribs :
- the Debian Jessie with Mate DE [3.10.102 BSP 2] by Lenny Raposo show me a nice 9.6 4096bits Private RSA / sec
while other dietPI and armbian get stuck to 6.4 4096bits Private RSA / sec.
So i decide to upgrade both the Debian Jessie Mate and dietPI to the latest kernel 3.10.105, run package update, then i force the CPU setting got from the debian to the dietPI :
sampling_down_factor = 1
sampling_rate = 2000000
sampling_rate_min=40000
up_threshold = 95
but got same result dietPI still show me 6.4 4096bits Private RSA / sec.
What do i miss ?
Any helps appreciate, thanks a lot

How many outputs can a GPIO drive?
I have several ADC's I want to send a clock signal too all at the same time, is there a general rule of tumb of how many devices a pine output can drive at once?
Thanks!
I should mention I'm clocking a dozen or so ADC0832's, they are all reading hall effect sensors
