VCC_IO pin
VCC_IO pin determines the voltage level of UART signals and the voltage level of GPIO output
signals. VCC_IO level also determines GPIO LOW/HIGH levels on each GPIO and UART input
pins.

Service pin
The SERVICE pin is used to set the UART1 into a known state. Pulling this pin LOW will activate
the service mode and set the UART1 into 38400, 8, N, 1. This is intended for service access of
the module, to have a known serial port setting in order to provide easy access to module settings.
The pin does not affect any permanent settings, nor does it change the mode of the module. It is
recommended to pull high or pull up by resistor to VCC_IO to return serial port 1 into the
configured state. When service pin is LOW the SL Commands are temporary forced to be ON
