Description

This USB-to-TTL adapter is based on the CH340 chip and is a low-cost solution for connecting micro-controllers and other digital serial devices to your computer. This board use 5V signals, but is also compatible with 3.3V. The module has both 3.3V and 5V as output with a maximum current of 500mA.

Question and answer

Q Belgium Herman Van WoenselNo question but a statement: the RX pin and the TX pin have been swapped on this programmer !! Very annoying if you want to get started one-two-three and trust the still qualitative look of this programmer.

According to the datasheet just 5V on the Rx and Tx pins. Do not connect directly to an ESP8266.
