The ESP8266 makes it easy to use the Arduino IDE and the Arduino Wire Language for IoT applications. To program the ESP8266 module press GPIO0 and RST button together and leave the RST button first and then release the GPIO0 button. By doing this ESP8266 will go into the programming mode.
Monitor sensors and control relays, FETs, PWM controllers, solenoids, valves, motors and much more from anywhere in the world using a web page or a dedicated server.
We manufactured our own version of the ESP8266 to fit into NCD IoT devices, offering more expansion options than any other device in the world! Integrated USB port allows easy programming of the ESP8266. The ESP8266 is an incredible platform for IoT application development.
To program this controller hold GP2 & Rest button and release rest first. when you do this you will see the LED will go dim, it indicates that the ESP8266 is in program mode. Once it’s in program mode you can start uploading your sketch using Arduino IDE.
GPIO14 — SCL
GPIO12 — SDA
Note: Please handle the USB connector carefully.
What is the I2C Interface?
The supplier of plug and play modular hardware using the I2C Interface connector standard. It allows you to chain together several devices on the I2C bus, and communicate to each device individually at high speed (subject to the limitations of I2C). The I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. These devices communicate on the power of 5V I2C data and provide 5V DC power through this connector. The advanced embedded devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. The device Package always includes a 6″ (152mm) 4-conductor I2C cable. The I2C based Mini Modules always include a 3″ (76mm) 4-conductor I2C cable. Cables and connectors are available separately for designers who would like to include their own I2C Interface into their designs.
