pisicaverde You will need a 5-12V, 2A power adapter. Any good wall adapter should work. There is no way to power it from the laptop. I gave up connecting it directly to PC, instead I'm using a serial forwarder with an arduino (link above).

- do not forget to power it separately; it won't work powered just from the microcontroller - the micro usb interface is not very useful, since you can't find any Mediatek win10 drivers. For giving serial commands, you'll need a serial forwarder uploaded intro microcontroller, like this one: https://pastebin.com/raw/xDaa1REt - the Vdd pin sets the voltage for logic levels. If connected to 3V, you can connect the board to 3V logic level breakouts, like ESP8266, without using level shifters - it has connectors for mic and headphones After this minimal setup, it seems reliable and easy to use.
