This project simplifies the process for new developers to get started with MicroPython on ESP32, ESP32-WROOM-32 or ESP8266 device.

🎯 It helps users to:

  • Flashing micropython firmware onto the supported device
  • Upload custom Python scripts to the device
  • Interact with the device using WebREPL for running Python commands remotely

🧩 Operating Environment

  • Windows 7 and above

🧩 Target Devices

  • ESP32
  • ESP32-WROOM-32
  • ESP8266
ESP32-WROOM32
ESP8266

📡 ESP Access Point

  • SSID: ESP328266
  • Password: 12345678

🔐 WebREPL

Password: 1234

🛠️ Installation Steps

Step 1: Connect Device

Connect your ESP device to your PC via USB.

Step 2: Flash Firmware

For ESP32 / ESP32-WROOM-32,
Double Click:
step1_ESP32_or ESP32WROOM_firmware_flash.bat

For ESP8266,
Double Click:
step1_ESP8266_firmware_flash.bat

💡 Remark: Please wait until you see ‘Press any key to continue’, then press any key to close the command prompt.
💡 Remark: Please ignore this if the flashing is functioning correctly. If flashing fails, you may click ‘boot’ button on ESP device when it shows ‘connecting……’.

Step 3: Upload Python Scripts

Double Click:
step2_upload_files.bat

💡 Remark: You may put your own scripts in ‘python_code’ folder before clicking ‘step2_upload_files.bat’.
💡 Remark: You may also customize ESP Access Point settings in /python_code/boot.py, as well as WebREPL password in /python_code/webrepl_cfg.py, before clicking ‘step2_upload_files.bat’.
💡 Remark: Please wait until you see ‘Press any key to continue’, then press any key to close the command prompt.

Step 4: Launch WebREPL in Microsoft Edge

Double Click:
step3_open_webrepl_Please_connect_WiFi.bat

WebREPL will be launched in Microsoft Edge.

Step 5: Connect your PC’s WiFi to ESP access point

💡 Remark: If ESP access point SSID does not appear, please press ‘EN’ or ‘RST’ button on ESP device or reconnect ESP device USB cable.

Step 6: Access to WebREPL

Click ‘Connect’ on WebREPL in Edge browser. Key in the WebREPL password and press Enter key.
