I built my daughter a wireless speaker box using this board, amplifier board and power supply. The Android app works quite well. I've been playing music for a few hours with the built in box with no problems. I am very happy. The company also sells a version of the board without Ethernet and Bluetooth for just $30. However, this is only available on the company's website. This one is worth a lot with the addition of Ethernet and Bluetooth.
