Introduction: ESP8266-01 Adapter

Hello guys,

here I want to show the way to my own build Adapter for the ESP8266-01.

When you look in the net no one can give a good and simple adapter for the ESP8266-01 to fullfill the following requests:

  • having a board for the ESP8266 which make the GPIOs easily available for use
  • having the possibility to to add PullUp resistors to the GPIO 0 and 2.
  • a voltage controller for a stable voltege for the ESP chip
  • an interface for the USB2TTL-Adapter
  • a button for reset
  • a button for flash

And thats it!

lets look to the first prototype...

Step 1: First Prototype of the Adapter

Thats the first Prototype.

Here you see the prototype with the following features:

  • a board which can carry the esp8266-01
  • an interface for:
    • 5 V
    • Gnd
    • GPIO0
    • GPIO2
  • an interface for the USB2TTL:
    • 5 V
    • Gnd
    • Tx
    • Rx
  • a reset button
  • a jumper for flash mode
  • Pullups and voltage controller
  • the adapter is ready for plugin into a case

Step 2: The More Professional Version

That's the next sample stage.

  • an enhanced interface:
    • 5 V
    • Gnd
    • 3,3 V
    • GPIO0
    • GPIO2
  • an interface for the USB2TTL:
    • 5 V
    • Gnd
    • Tx
    • Rx
  • a reset button
  • a button for flash mode
  • Pullups and voltage controller

And the adapter is ready for plugin into a case...
