Keyes EB0042 Super-Mini Digital Amplifier Board w/ USB Power

Build robots and interactive electronics with this mini digital power amplifier board.The ultra-thin board is a high-performance digital amplifier that can be used to create external speakers for smart devices.

Fitted special internal output processing circuit, the digital amplifier is able to achieve maximum power output under lower voltage to help save power. The cancellation of traditional LC  network leads to much lower EMI value, meanwhile the built-in standby switch creates a high-gain buffer amplifier and short-circuit protection.

Expand your robotics with this super-mini amplifier board. Power up using single lithium cells, USB or four 1.2V batteries.
