USB to UART/ESP8266 Adapter Programmer for ESP-01 WiFi Modules with CH340G Chip

The USB to UART/ESP8266 Adapter Programmer for ESP-01 WiFi Modules with CH340G Chip is designed to convert the signal from a USB interface on a PC or laptop to match the serial module ESP8266. The CH340G chip ensures reliable and high-performance operation, and the adapter is compatible with most Windows systems. Integrated capacitors ensure a stable current of 1000 μF.

This adapter module features the CH340G USB to TTL driver IC onboard, allowing for easy ESP-01 functional debugging using your computer. The ESP-01 serial wifi module can be directly plugged into the yellow pin header without the need for any connecting wires.

  Features:  

• Uses the CH340G serial port chip for stable performance and compatibility.
• Supports all basic Windows versions.
• Integrated 1000μF solid capacitors on the adapter plate ensure a stable current supply, preventing WIFI module crashes.
• Uses a 3225 SMD crystal oscillator to improve the stability of serial work.
• Features an on-board toggle switch for selectable working modes: UART side for serial TTL debugging using AT commands, PROG for firmware programming.
