Webduino Smart

Goals

  • [OK] Flash Webduino with different IDEs
  • [OK] Check Components : pins, photocell, RGB LED, button
  • [OK?] Use OTA

Description

  • Webduino USB port is only used to power the board, not for upload and monitoring
  • The chip is labeled ESP8266MOD by AI Thinker, in fact it is an ESP-12F, same as Wemos D1
  • The board includes a photocell, an RGB led and a button.
  • Unofficial tutorial in ~english, with how to flash webduino with FTDI

Wiring and flashing

Plug Webduino Smart using FTDI 3.3v module. Webduino and the FTDI must be powered. Webduino is powered through its micro USB port.

         Tx     Rx    
ftdi     Rx     Tx     Webduino
         Gnd    Gnd

For flashing, on Webduino Smart connect GPIO 0 to GND. (RGB goes light blue)

For rebooting, on Webduino Smart connect RST to GND

Flashing usual sequence is:

  1. Set flash position (GPIO0 on GND)
  2. Power the FTDI and the Webduino
  3. (RGB goes light blue) Disconnect GPIO 0
  4. Upload sketch… Webduino should restart in normal mode.
  5. Or disconnect GPIO 0 and restart using RST or Webduino power

Arduino IDE

Select Board : “Generic ESP8266 Module”

Platformio

Got it to work as a Wemos d1!

  [env:d1]
  platform = espressif8266
  board = d1
  framework = arduino

Components

I got blink sketch using LED_BUILTIN (2)

RGB LED
