Introduction: More GPIO for ESP8266 - 01

Picture of More GPIO for ESP8266 - 01

The esp8266-01 module has a lot of applications programming either in company with arduino, or by programming only from the Arduino IDE interface.
This module is ideal for applications via wireless data transmission and the cost is the best unlike other costly inhalambricos modules. Since the ESP8266 - 01 only has 2 GPIO available,

I was forced to get another gpio, carefully perform welding on pin 14

Step 1: Knowing Arduino IDE

Installation and configuration of Arduino IDE for programming ESP8266 Module - 01

Step 2: Components and Materials Required for Testing

Picture of Components and Materials Required for Testing

1 Module ESP8266

1 Soldering iron with fine tip

1 wire thin copper

soldering tin

select pin 9 or GPIO 14

select GPIO pin 9 or 14 since it was the easiest position to be soldered copper wire.

Step 3: Testing...

classic blink test is performed and works very bn our new GPIO

If in the future there is a need soldare more pins ....

More Test....

Esp8266 blink test with new Arduino IDE 1.6.5 : PDA_Control

ESP8266 firmware update with Flasher ESP8266 : PDA_Control

Excellent information. Thank you! Question: are the other pins in the ESP chip also accessible that way? Can we use all of them or is there a limitation?

Hi, there is no limitation, it only requires a good welder and a lot of patience, look what a colleague did,
