Introduction to Go to Cloud (G2C) click

Go to Cloud (G2C) click is composed of two main components:

∫ MK64FN1M0VDC12, a 32-bit ARM® Cortex® M4 microcontroller, from NXP

∫ ESP WROOM-02, a Wi-Fi connector module, from Espressif systems

The ESP-WROOM-02 is used as the connector module which can establish a link with the Click cloud service over the Internet.

It is an all-in-one solution, with the complete Wi-Fi stack on-board, which allows a very simple operation. This feature, along

with the proven reliability, small form-factor, and low count of components it requires, makes the ESP WROOM-02 module

an ideal solution for using it on the Go to Cloud (G2C) click.

The ESP-WROOM-02 module uses the UART communication interface, and it can be controlled by using simple AT

commands. However, the MK64FN1M0VDC12 MCU is added too, introducing an additional application layer, exposing

only a set of commands that allow connection with the Click Cloud, reducing the possibility of errors and failures due

to wrongly set connection parameters and simplifying HOST MCU application. The MCU is also used to drive status

LEDs, which are used to indicate a successful connection to the Internet, a successful connection with the Click Cloud

service, as well as some other types of indication.

Finally, there is a micro USB connector, which is used to update the firmware of the Go to Cloud (G2C) click. The

firmware update is simple, error-proof, and straight-forward. More information about the update procedure can be

found in this manual.
