This is a version invented by Lolin with a CH340G USB-TTL chip instead of the Silabs CP2102 from V1.0. As shown, it has the same pinout structure with V1.0. But this board is slightly larger than the V1.0. These are the boards that carry the “NodeMCU” name. But they are not the only one featuring the ESP8266. See Adafruit Huzzah and WeMos
How to connect a Raspberry Pi to a serial USB port with Python
May 01, 2020Raspberry Pi can be used to interface with the real world from its GPIO, for example, by controlling a stepper motor. You can also use Raspberry Pi to dialog with some devices—like Arduino—by using a serial USB port. In this guide, I'll show you how to connect your Raspberry Pi to a serial USB port and read its values with Python from the terminal
