Works perfectly!!
I bought a 5 pack of ESP8266-01S boards that came with a USB programmer but I could not get it to work. This one worked first try. Definitely recommended.

The CH340 based module can be used as a programmer as well, but only with a (simple) trick. It is easy if you know how to set the ESP8266 chip into bootloader mode. But the CH340 module is meant to be a communication interface, not really a programmer.
This module here, with the CP2104 USB-UART chip, is a true programmer for the ESP-01 and ESP-01S and makes things a lot easier.
