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...
