Product Description
What is it?
A CP2102 3.3V USBToUART converter support 400mA+ current. Program ESP8266 module just like NodeMCU.
Why did you make it?
The common USB to UART converter supports only 100mA current. The converter supports 400mA+ current. It's good for programming ESP8266 (ESP-01 and ESP-11).
For program with Arduino IDE, the circuit does the trick for auto reset. Thanks for NodeMCU team!
Features
- ESP-01 and ESP-11 supported
- A Reset button and a flash button for esp8266
- No need press reset button when flash esp8266 with Arduino IDE, just like NodeMCU does
- Operating voltage:3.3V
- System support:Windows 98SE/2000/XP/Vista/Window7/Mac OS 9/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:
| flasher pin | ESP module pin |
| VCC | VCC |
| GND | GND |
| TXD | RXD |
| RXD | TXD |
| RST | RST |
| GPIO0 | GPIO0 |
| CH_EN | CH_EN or CH_PD |
Setup Arduino IDE for programming esp8266
Use the ESP8266 flasher for Arduino IDE without pressing the reset button. Watch the Video for the demo.
- Install Arduino 1.6.5 from the Arduino website.
- Start Arduino and open Preferences window.
- Enter /stable/package_esp8266com_index.json into Additional Board Manager URLs field. You can add multiple URLs, separating them with commas.
- Open Boards Manager from Tools > Board menu and install esp8266 platform (and don't forget to select your ESP8266 board from Tools > Board menu after installation).
- You can programming ESP8266 module by choose the board type "NodeMCU V1.0" now.
For ESP-01 or other modules, they have only 512K or 1M flash. So I added a pull request for them. You can make the change manually now.
- Find out the board file for esp8266. For OS X, the file is locate at ~/Library/Arduino15/packages/esp8266/hardware/esp8266/1.6.5-1160-gef26c5f/boards.txt, please fix the 1.6.5-1160-gef26c5f for your PC.
- Add the lines like the commit.
- We have a new option "Reset Method" now. For programming without press the reset button, you should choose Reset Method "nodemcu".
