∫ CTS - Clear to send
[1]
- (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
[1]
- (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. There is also a secondary function of this pin: if set to a HIGH
logic level during the boot-up sequence, the five-second bootloader timeout will be completely skipped, allowing for
a faster start of the Go to Cloud (G2C) click. More information about the secondary function of this pin is provided in the
Boot-up section of this manual.
∫ GP0, GP1 - General purpose pins
[1]
- (INPUT) A LOW logic level on this pin means that HOST MCU
is ready to receive data sent from Go to Cloud (G2C) click.

The current version of the firmware (ver.F091) does not have these options implemented yet, but they are
planned to be added in future updates.
