### Serial-to-USB adapter with 3.3V power
* [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) - confirmed working for flashing and setup of a Sonoff Basic R2, but may require an external 3.3v supply for other devices
* [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) - also work but using an external 3.3V supply is necessary and thus not recommended for beginners.
* [RaspberryPi](https://github.com/arendst/Sonoff-Tasmota/wiki/Flash-Sonoff-using-Raspberry-Pi) - only for advanced users. External 3.3V supply necessary.
* [NodeMCU](https://en.wikipedia.org/wiki/NodeMCU) and [D1 mini](https://wiki.wemos.cc/products:d1:d1_mini) (Pro/Lite) boards have a micro USB upload port and don't require an adapter.
