Flashed four ESP8285 devices with ESPHome the first day I got it and had absolutely no problems. I bought a cheap programmer directly from a Chinese reseller website and spent hours debugging issues before I concluded it was a bad programmer; this FTDI adapter immediately fixed my issue. Worked without additional configuration when plugged into my laptop running Bazzite Linux. Instructions include a QR code for Windows drivers, which I installed then tested this adapter to confirm it works on a Windows machine as well. Review: GREAT USB adapter with all RS-232 signals, also included interface cable! - GREAT USB adapter with all RS-232 signals. Used to modulate a DTR pin from a USB port with excellent results - solved a problem I'd been working with for WEEKS! Not mentioned was that an approximately 11-inch interface cable is also supplied, and the unit came with TX and RX pins shorted with a jumpter to make it easy to see the interface was working. I will definitely recommend this product to others! ## Features - Support 4 kinds of TTL levels:This is a versatile USB to TTL converter.
