I'm a new comer to arduino and I need a shield to help control 4 different items with various power for each. I need to supply 10W to a pair of speakers each needing 5W and another 6W to another set of speakers each needing 3W. I also need about 2.3V for my VU meter by Great Scott with just a little more power for my lcd screen by arduino. I'm also including TDA7492P 25W+25W Wireless Bluetooth 4.0 Audio Receiver Digital Amplifier Board. So I'd like to add this features together with 2 analog inputs and 3 digital for on and off of whole system, switching from radio to Bluetooth, and one to vary the on and off of the VU meter.
