General Orange Pi Zero questions

Hello,

I am trying to find some information regarding OPI controller but very very pour,
maybe you can help!

1. I can not find the BCM2835 C library for OrangePi Zero. Under FAQ it sais you have it! Where?
2. What is maximum curent drwan on each GPIO (in order to do not destry it)? What is the maximum curent drawn on all GPIOs?
3. What is GPIOs maximum low level voltage? What about minimum high level voltage?
4. What is the minimum powering requirements for Orange Pi Zero? 5V, 1.5A should do it?

Thank you in advance!

BCM2835 is SOC used in RPI.
There is no BCM2835 library in OPI.

I use GPIO's to control relays/read values, never use them directly, use some circus before that to protect them. ULN2003A is perfect for the job.
Also use 3.3 to trigger gpio's no more.

Hello friend,

Thank you for your answer.
I know that BCM2835/6 is as SOC for Raspberry but, over website, I can see that WiringPi was also updated in order to work for OPI.
I was thinking that this BCM2835 was also updated.

What are C libraryes posibilities for OPI?

Hello friend,

Thank you for your answer.

As far as I know, there is only this in the C library which can be used in ZERO.

I'd like to know other C library.
