UART to USB flasher Rev4 ESP8266 BLE module
Change For Rev4
Replace CP2102 to CP2104
Can also support ESP32
What is it?
A CP2104 3.3V USBToUART converter support 400mA+ 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 400mA+ current. It’s good for programming ESP8266 and ESP32 module
For program with Arduino IDE, the circuit does the trick for auto reset. Thanks for NodeMCU team!
Based on CP2104
ESP8266 and ESP32 supported
A Reset button and a flash button
No need press reset button when programming esp8266 / esp32 with Arduino IDE
