محول مبرمج ESP01 من ريد تاغ كندا UART GPIO0 ESP-01 محول ESP8266 CH340G USB الى ESP8266 وحدة تطوير واي فاي لاسلكية تسلسلية لاردوينو

Using CH340 serial chip, stable performance, good compatibility, almost all the Windows system can compatible.
Using 3225 chip crystal, to enhance the stability of the serial port. Adapter board integrated 1000uF solid capacitor, to ensure that the current supply, don't make WIFI module with power problem crash no response.
This adapter makes it easy to connect the ESP8266 to the PC via the serial port.
The module is based on the USB-UART bridget CH340 from WCH which is compatible with all platforms.
The schematic is open source and easily available
Refer to the CH340 datasheet and most important to the NodeMCU V0.9 which use the CH340 and already implements this solution.
