Product Name 

ESP-01 Adapter 3.3V 5V

Product Description 

This USB to UART/ESP8266 Adapter Programmer for ESP-01 WiFi Modules with CH340G Chip converts the signal from a USB interface to a PC / laptop to match a serial module ESP8266. This converter module has CH340 chip which is reliable and with high performance. It is compatible with most Windows systems. The adapter features integrated capacitors to maintain a current of 1000 μF. USB to ESP-01 adapter module has CH340G USB to TTL driver IC onboard, so you can easily use your computer to do ESP-01 functional debugging. ESP-01 serial wifi module can be directly plugged into the yellow pin header without any connecting wire. USB to UART/ESP8266 Programmer used for an ESP-01 module with the ESP8266 chip.
