Page 4: Introduction To Go To Cloud (G2C) Click
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. - Page 5 Figure 1: Figure 2: ESP-WROOM-02 MK64FN1 M0VDC12 MCU 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.

Page 7: Mikrobus ™ Pins
An additional JTAG interface in the form of 2x5 pin header is used only during the production phase for the upload of the initial firmware and it should not be used by the user, as it may lead to malfunction of the Go to Cloud (G2C) click due to an internal firmware damage. -
Page 8: Onboard Indicators And Led Indicators
Onboard indicators and LED indicators The Go to Cloud (G2C) click requires both 3.3V and 5V for a proper operation. NOTE: Pins description: ∫ RST - Hardware reset - (INPUT) This pin is used to reset the MCU. This pin is internally pulled up to a HIGH logic level. Driving this pin to a LOW logic level for 50 ms, a reset function will be performed. -
Page 9: Uart Interface - Configuration
∫ CTS - Clear to send - (INPUT) A LOW logic level on this pin means that HOST MCU is ready to receive data sent from Go to Cloud (G2C) click. ∫ RTS - Request to send - (OUTPUT) A LOW logic level on this pin means that the Go to Cloud (G2C) click is ready to accept incoming data from the host MCU. -
Page 10: Boot-Up Sequence
The complete control of the Go to Cloud (G2C) click is done over the UART interface, by using AT commands. The list of the available AT commands, along with the explanation and example for each of them can be found in the AT Command Manual. - Page 11 mode. If there is no response from the USB HID Bootloader application while the Go to Cloud (G2C) click is in the bootloader mode, the normal operation of the Go to Cloud (G2C) click will be resumed and the MK64F MCU will not be visible for the USB HID Bootloader application anymore.

Page 12: Firmware Update
Firmware update The G2C click is shipped with the latest version of the application will detect the onboard MK64F MCU, as firmware. However, the firmware will be continuously displayed on the picture below: improved in the future. Therefore, the Go to Cloud (G2C ) click has a firmware update option, in a form of a micro USB connector (CN1) and an implementation of the HID bootloader within the firmware itself. - Page 13 Note that there is a five seconds timeout interval during which the Go to Cloud (G2C )click operates in a firmware update mode as explained in the Boot-up sequence section of this manual. After this, the Go to Cloud (G2C )click is restarted and will continue running in a normal mode, completely skipping the bootloader, and will be undetectable for the HID bootloader application.
