Quick way to flash ESP8266 12E with Tasmota firmware

This is a quick video just to show you how you can flash this bare ESP8266 type 07 or 12E with Tasmota Firmware. It also can be used to upload code from Arduino IDEA.

What you need, besides of course a ESP8266, is a FTDI adapter that allows you to connect TTL or serial interfaces devices to USB.

You will also need a 10k resistor, wires and soldering iron.

You can start soldering and connect VCC 3.3V and GND to FTDI, make sure that your FTDI provides 3.3V.

Then connect the PIN RX from ESP to TX on FTDI and TX from ESP to RX in FTDI.

The PIN EN (Enable) must be also connected to VCC 3.3V

Then you need to connect GPIO0 to Ground, this PIN when connected to Ground on boot, tells the ESP to enter on flash mode.

GPIO 15 must also be connected to ground using the pull down resistor of 10k, like shown in the schematic.

This is everything that you need, then start the Tasmotizer tool, select the latest release .bin file.

Connect the FTDI to your computer USB port and start flashing it.

After completing the flashing process, remember to disconnect the GPIO0 from Ground and then power cycle your ESP again (you can do it disconnecting and connecting again the FTDI USB cable).

Check your wifi networks and you should see the Tasmota AP enabled. Connect to it and provide your wifi credentials and save. Your ESP will reboot. Using the Tasmotizer or by accessing your router, you should find the IP that your Tasmota is serving.

Now you can start any project connecting sensors and other external components to your ESP8266-Tasmota.

See you in the next video where I will show you how to use the Tasmota DeepSleep function that allows you to connect your ESP with a battery bank that lasts for a long time due minimal consumption of current.
