This ESP8266 host adapter was designed specifically for the Adafruit Huzzah version of the ESP8266, allowing I2C interface to our entire NCD product line.
Integrated USB port supplies power and programming to the ESP8266.
The ESP8266 is an incredible platform for IoT application development. The ESP8266 provides a mature platform for monitoring and control applications using the Arduino Wire Language and the Arduino IDE.
The Adafruit ESP8266 is available from www.adafruit.com.
RevA I2C connections are 2,14( Use Wire.begin(2,14); //to configure I2C)
What is the I2C Interface?
NCD is the creator of plug and play modular hardware using the NCD I2C Interface connector standard. NCD I2C devices allow 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 NCD I2C Interface uses a standard 4-Pin I2C Input and I2C Output connector. NCD I2C devices communicate 5V I2C data and provides 5V DC power through this connector. NCD I2C devices use standard I2C communications for all data transport, which is supported by nearly every microcontroller in production today. The NCD I2C Interface is strictly a 5V standard, which is ideal for transport across longer cables. NCD I2C devices always include a 6″ (152mm) 4-conductor I2C cable. NCD I2C 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 NCD I2C Interface into their designs.
