Key Features:
Applications:
It is a good companion of ESP8266. This USB to serial module converts the USB interface to the serial port. And it is suitable for ESP8266.
It is using CH340 serial chip. It is a more stable performance, and it is power compatible.
This module supports all Windows systems.
The main purpose of this USB to Serial connector is to connect ESP8266 and PC via the serial port.
It consists of a CH340 chip.
It has high-speed CPU frequency.
It can be used as a serial port WIFI.
Features:
This module requires a 3.3 volt supply for VCC, and 3.3V logic.
Connecting RX or TX on 5V Arduino will destroy this module.
You must use a logic level converter, or a 3.3V Arduino.
The 3.3V supply on the Arduino Uno has inadequate current capability to power this module.
You must provide a separate, higher 3.3V supply(about 300mA or better).
