I gave you some advice on watching out for Gnd and video, and using the pp points.

Using headphone jack for GPIO output

Hi, I am considering using 3.5mm headphone jack on Raspberry Pi 2 B as GPIO output but I am not sure if this is safe. I have already mounted reset switch and RCA socket (SPDIF output from TinyTOSLINK board) to my Pi's casing and woudn't like adding another interface. I also don't want any cables com...

Re: TinyTOSLINK (digital audio output) now for B+, too

Hi All, Did anyone try to use BenjaminKe's or [IDC]Dragon's board on Raspberry Pi 2 B with Raspbian Jessie? I'm having trouble with getting it to work. I don't want to use OpenELEC nor any other distro - I prefer to make it working on clean Raspbian. I added HiFi Berry to device tree and disabled de...

The best solution would be to have both RCA and TOSLINK connectors in case I needed to switch to TOSLINK. Is it possible with TinyTOSLINK to send signal to both optical and electrical outputs? I wo...

Re: TinyTOSLINK (digital audio output) now for B+, too

Hi All, This is my first post so please be forgiving :) I also think this is a great project that perfectly fills the gap of Raspbery Pi digital audio support. I'm about to order RPI 2 b but I need to be sure it can support digital audio output because I want to use it as media center and connect it...
