This is our fanciest driver board. It's best for supporting high resolutions, has multiple inputs, and can support HDMI audio! That means you can have a full A/V system with only one data cable. There's a stereo amplifier onboard that can driver 4 ohm speakers directly
You can solder 3W 4 ohm speakers directly to the amp, like this one.
Or use this ready-to-go stereo speaker set, you can just plug the connector in directly!
Audio quality and video resolution
We're not 100% sure of this but it seems like the amount of sound data you can transfer is related to the set HDMI resolution.
Since this driver has a built in video scaler you can display 1280x800 video on a 800x480 display, it'll just be smaller. We noticed that many operating systems/programs try to push high quality (44.1khz 24 bit) audio and it'll stutter if the resolution is set to something like 800x480
So, if you can set the audio quality in your OS, set it to 44.1KHz 16bit or 22.1KHz 16bit or you can just set the resolution of the screen to like 1280x800 or 1280x720 type size. On a Raspberry Pi, resolution is set in /boot/config.txt, on windows, right click on the background and select Screen Resolution from the menu
The Power, VGA and A/V JST ports are good alternatives to the main inputs if you don't want bulky cables coming out the sides of your driver board.
Power input: 9-12V DC
