The gpio pins of the Rock pi x model b development board support maximum how many volt inputs. Where can I find the related datasheet.
The RK3399 datasheet can be found here: https://www.rockchip.fr/RK3399%20datasheet%20V1.8.pdf
Thank you for the information. but I guess this chip is not used in the rock pi x model b development card.
check the intel TRM manual about the atom x5-z8350, https://wiki.radxa.com/RockpiX/hardware
Oh, I’m sorry, I misread your post. My apologies.
Thank you again for your interest and reply.
