CH340 USB to ESP8266 ESP-01 ESP-01S Wi-Fi Adapter Board

• 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.
• Its a great programmer for the ESP-01. Its very easy to just plug it in and send AT commands, or flip the switch to program and upload a sketch from Arduino IDE. Also you don’t need a separate 3.3V power supply to power the ESP-01.

Features:

• Working voltage: 4.5V – 5.5V (On-board 3.3v LDO Regulator)
• Working current: 300mA(LDO regulator can supply)
• Selectable working mode: On-board toggle switch. UART side for serial TTL debugging by AT commands, PROG for firmware programming
• USB to serial TTL chip: CH340G
• Logic level: 3.3V
• Applications: Home automation, Sensor networks, Industrial wireless control, etc.

Other Comments:

• 1. The ESP-01 boards are super-simplified ESP8266 and these allow for flashing during development.
• 2. This little gadget makes programming the ESP 01s a breeze. It’s a must have for installing firmware.
• 3. Not at all my first programmer for these boards, but the easiest by a landslide! No buttons to hold down or wiring to do.
• 4. This worked, didn’t try the debug ger but the upload was flawless, very easy and it didn’t seem like it would break even when I stored it in tight confines. Please make sure to set your baud to at least 115200 yes the USB will work either way, but the extra speed will help you.
