Yes please! This incredibly small stereo amplifier is surprisingly powerful. It can deliver 2 x 2.8W channels into 4-ohm impedance speakers (@ 10% THD) and it has an i2c control interface as well as an AGC (automatic gain control) system to keep your audio from clipping or distorting.\u003c\/p\u003e\n\u003cp\u003eIf you don't want to use I2C to control it, it does start up with 6dB gain by default and the AGC is set up for most music playing. We do suggest using it with a microcontroller to configure it, however, since it's quite powerful. Settings are not stored in the chip, so you'll need to adjust any gain \u0026amp; AGC amplification settings every time the amp is powered up.\u003c\/p\u003e\n\u003cp\u003eInside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient (89% efficient when driving an 8Ω speaker at 1.5 watts) - making it perfect for portable and battery-powered projects. It has built-in thermal and over-current protection but we could barely tell if it got hot. This board is a welcome upgrade to basic \"LM386\" amps!\u003c\/p\u003e\n\u003cp\u003eThe inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to the ground. The outputs are \"Bridge Tied\" - which means they connect directly to the outputs, with no connection to the ground. The output is a ~300KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output to another amplifier, it should drive the speakers directly.\u003c\/p\u003e\n\u003cp\u003eComes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include 3.5mm screw-terminal blocks so you can easily attach\/detach your speakers, and some header in case you want to plug it into a breadboard. Speakers are not included, use any 4-ohm or 8-ohm impedance speakers.\u003c\/p\u003e\n\u003cp\u003eOur awesome tutorial and Arduino library will let you set the AGC configuration (you can also just turn it off), max gain, and turn on\/off the left \u0026amp; right channels all over I2C!

The CP2104 has better driver support than the CH340 and can do very high speeds, and variable speeds without stability issues.

Works excellently with any Arduino, ESP8266, ESP32 or any other microcontroller that uses an 'FTDI port' for communications and upload.

Sure you \u003cem\u003ecould\u003c\/em\u003e try to hot-air that regulator off, or you could jerry-rig a relay. Or, use a 555?

It will take care of turning your project on\/off using a built in timer that can vary from once every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.\u003c\/p\u003e\u003cp\u003eUsage is easy. First, set your desired delay by adjusting the on-board trim pot: nearly-all-the-way-to-the-left is \"once per 100ms\" and all-the-way-to-the-right is \"once every 2 hours\". Then, connect VDD up to your 3-5V power supply and then your project's power-in to the Drive pin. Finally, select a signal pin from your project to the Done pin.
