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!

Hello,

Can a "hat", like the twinind 3.14-2 be mounted (screw/holder positioning) on top of a Pine64?

I would like to switch from rpi3 to pine64 on my pet project, and this is a crucial part. As I've seen the GPIO layout is the same.

Thanks in advance,
Gergely

Good morning,

i'm looking for a lcd screen without touch screen and larger than pine 64 table(7''). I found one but i don't know if i need to have into account anything more. LCD Screen is HSD101PUW1-A00. I would like to run my pine64 with debian and this screen.

Here you have the datasheet:
http://www.yslcd.com.tw/docs/product/HSD101PUW1-A00.pdf

I can check it has a MIPI protocol with 4 lanes, but the connector has 34 pins. I think that i can make the conector with a ffc(do it myself) conecting correctly the pins but i don't know if i need to have into account anything more to run the LCD Screen...

Another question is about the squematic about MIPI-LCD, i don't understand the squematic because it seems the conector has 32 pins but actually the conector has 30 pins...could anybody explain me that?Are there more information about this conector DSI and its interface?

So...summarizing:
1.- Do i need to have into account anything more to run the screen?(driver for linux or something like that)
2.- I don't understand well the squematic of MIPI-LCD


Thank you!

Any chance a linux image for Rock64 run on Pine64?

I wish o could run debian strech kernel 4.*.

Hello

I happened upon the Rock64 whilst looking for a better sound solution for a project I'm trying to get working with a Pi3. I need to record ultrasound through an electret mic with at least 192kHz sampling rate and there only sound cards for the Pi which reached 192kHz are no longer available. Whilst most mics aren't spec'd to record that high they some will apparently pick up such sound reasonably well.
I see that the Rock64 has an on board microphone - what is the maximum sampling rate?


I've only just got into this sort of thing so I hope my question makes sense

Thanks

Duncan

I bought a battery and installed it on my pine, but when the board isn't plugged directly into the USB Charger nothing but the most basic board functions work. Anything in the USB slot is not read, there is no audio output from the 3.5mm jack, there is no HDMI output. Is there something wrong with my board or maybe the OS, or is it so limited that my battery purchase was a total waste? I mean between this and not being able to turn the board on/off I'm about ready to ditch it and get a Raspberry Pi, which is a shame because I've wasted a lot of money at this point.

edit: I should mention I'm using the Android 5.1 LCD build, in case that's the issue. Bluetooth and WiFi do still work while on battery.

I must say I was blown away by the Pinebook! 


I honestly thought it would be a lightweight laptop with cheaper materials, but boy was I wrong! This thing feels more expensive than some of the laptops I've bought over the years! The system is very fast and beautiful, definitely surpassed my expectations.

I can't wait to try Luke's RetroArch image on it
