Esp8266 esp01 ใช้ usb serial ตัวไหนครับ?

ใน nodemcu ใช้ CH340 หรือ CP2102

ีusb ttl ใช้รุ่น FT232, CH340G or CP2102

If you are using a bare ESP-XX module then you will also need to connect to the 3.3V TTL serial port during development. There are many USB to serial converter modules available which present a virtual serial connection to your host PC or laptop and connect to the chip's serial interface. These are based on either the FT232, CH340G or CP2102 chip. Note:

• The FT232 is made by FTDI, but there are a number of unlicensed FT232 clones available and some modules use these. These FT232 clones can cause problems on Windows PCs because the FTDI-supplied FT232 driver now includes detection logic and will not communicate to unlicensed clones.
• The modules based on the CH340G or CP2102 chips do not have this issue.
• How must by a serial module what can drive TTL at 3.3V levels. Many are 3.3V/5V jumpered or DIP-switchable.
• Some modules also provide a 3.3V VCC line but these are typically at 300mA or so and cannot provide enough power to run the ESP chip during WifI operation. So a separate 3.3V power supply is needed. A common approach is to use a 5.5V to 3V power module, and again there are many options available online for a few $.

ตัวนี้ใช้ได้ไหมครับ ใช้กับ nodeMCU ครับ

ใช้ได้ครับ nodemcu ก็ใช้ตัวนี้เป็น usb serial
