[[TuyOTA]]) * Beefy FTDI ([example](https://www.sparkfun.com/products/13746)) - this one should provide enough power to work correctly. * CH340G based USB-Serial board ([example](https://www.sparkfun.com/products/14050) - many people have had good luck with these types of boards and the generic ones seem to work just fine. * Basic FTDI USB-to-Serial Converter/Programmer ([example](https://www.sparkfun.com/products/9873)) - this works for some people but some people have trouble using this to power the device and flashing does not always work. Using an external 3V3 supply might be necessary, since the FTDI part is only rated to supply 50mA and that is much less than the esp8266 requires.
