### Device with an ESP8266/ESP8285 chip
Any [variation](https://en.wikipedia.org/wiki/ESP8266#Espressif_modules) of the [ESP8266 chip](https://www.espressif.com/en/products/hardware/esp8266ex/overview) can be flashed with Tasmota.

The [power supplied to the device](https://www.letscontrolit.com/wiki/index.php?title=Power) is **one of the most important elements** for both flashing the device and for stable operation. You must ensure that the device receives sufficient power (current AND appropriate voltage level) to properly flash the firmware on the device.
* [CH340G](https://cdn.sparkfun.com/datasheets/Dev/Arduino/Other/CH340DS1.PDF) is a reliable and very cheap adapter (example [1](https://www.sparkfun.com/products/14050), [2](https://www.aliexpress.com/item/1PCS-CH340-module-instead-of-PL2303-CH340G-RS232-to-TTL-module-upgrade-USB-to-serial-port/32761423124.html?spm=2114.search0104.3.115.3d405236NZWG1Z&ws_ab_test=searchweb0_0,searchweb201602_7_10065_10068_10547_319_317_10548_10696_10084_453_10083_454_10618_10304_10307_10820_10821_537_10302_536_10843_10059_10884_10887_321_322_10103,searchweb201603_52,ppcSwitch_0&algo_expid=c0daff3f-102f-44c1-8856-75e92423eecd-15&algo_pvid=c0daff3f-102f-44c1-8856-75e92423eecd&transAbTest=ae803_3)).
* [FTDI FT232](https://www.ftdichip.com/Products/ICs/FT232R.htm) - these adapters have a lot of fakes in the market so buy only from reliable sources ([example](https://www.sparkfun.com/products/13746)). Buy only the variant with a separate 3.3V regulator on PCB!
* [CP2102](https://www.silabs.com/documents/public/data-sheets/cp2102-9.pdf) or [PL2303](http://www.prolific.com.tw/UserFiles/files/ds_pl2303HXD_v1_4_4.pdf) - works with certain devices, but using an external 3.3V supply might be necessary. Not recommended for beginners!
