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.

Description

Don’t send 5 V signals to your ESP8266. The use of an ESP8266 with Arduino requires logic level translation of the UART signal, as provided by this easy 3.3 V – 5 V adapter. It makes the ESP-01 ESP8266 WiFi module (150445-91) the easiest WiFi transceiver for your Arduino (5 V).

• Adapter module for ESP-01 Wi-Fi module
• 3.3 V voltage regulator circuit & onboard level conversion for easy use of 5 V microcontroller with ESP-01 Wi-Fi module
• Compatible with Uno R3
• 4.5 ~ 5.5 V (on-board 3.3 V LDO Regulator)
• Interface logic voltage: 3.3 V / 5 V compatible (on-board level shift)
• Current: 0 – 240 mA

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. It has CH340G USB to TTL driver IC onboard, so you can easily use your computer to do with ESP-01.
