What's it?

A CH340 3.3V USBToUART converter support 1000mA+ current. Program ESP8266/ESP32 module just like NodeMCU. It has smaller size than rev2 and we make it breadboard friendly. You can also use the flasher to programming ESP32 without pushing flash button.

Why did you make it?

The converter supports 1000mA+ current. It's good for programming ESP8266 and ESP32 moduleFor program with Arduino IDE, the circuit does the trick for auto reset.

Features

• ESP8266 and ESP32 supported
• Breadboard friendly
• A Reset button and a flash button
• No need press reset button when programming esp8266 / esp32 with Arduino IDE
• Operating voltage：3.3V
• System support：Windows 98SE/2000/XP/Vista/Window7/Windows 10/Mac OS/Mac OS X/Linux 2.40
• Output current：400mA+ (a MIC5219 LDO)

Pinouts

For programming other ESP8266 modules such as ESP-12 or ESP-07, wire the pins like these:

For ESP8266

flasher pin ESP8266 pin VCC VCC GND GND TXD RXD RXD TXD RST RST GPIO0 GPIO0 CH_EN CH_EN or CH_PD For ESP32

flasher pin ESP32 pin VCC VCC GND GND TXD RXD RXD TXD RST EN GPIO0 GPIO0 CH_EN Not wire
