Source 5V switching regulator 10A (50W)
This audio converter converts the digital signal (optical or coaxial) in a stereo analog signal. The signal received on the input SPDIF (TOSLINK) or coaxial output is converted and transmitted to stereo L / R RCA jacks standard.
The adapter is designed to transfer the HDMI signal from a computer, laptop, PS3, Xbox etc. to a VGA signal and display at high resolutions such as monitors, LCD TVs, projectors, etc. This is a portable adapter that makes transfer from HDMI HD in to VGA output.
Product Features : Supply voltage: 2.4V - 5.5V; Current consumption: 30mA; Integrated microphone on board; An integrated amplifier that can directly control an 8 ohm impedance loudspeaker and 0.5W power; Record and play buttons; It can record up to 16 seconds.

PCM5102A Audio Stereo DAC with 32-bit 384 kHz PCM Interface
The ideal module to play sounds without the need for a microcontroller. Small and portable, at the touch of a button, will play the chosen sound. It is independent, all it needs is power supply between 3V and 5.5V.
3.5 mm 4-Pin Audio Cross-Over Adapter Cable, Black
Adafruit I2S Audio Bonnet for Raspberry Pi - UDA1334A
3.5 mm plug to 2 x RCA sockets stereo audio cable, 0,2 m
The sound board is designed to be simple: it does not have polyphonic ability, can't play MP3's (MP3 is patented and costs $ to license, so this board uses the similar but not-patented OGG format, there's tons of free converters that will turn an MP3 into OGG), isn't reprogrammable or scriptable, and you can't have any other kind of trigger type.
