The module may be integrated with other antennas. In which case, the OEM installer must certify
the design with respective regulatory agencies.
2.4.2
Internal antenna
NORA-W366 modules have an internal antenna that is specifically designed and optimized for u-blox
Wi-Fi, and Bluetooth LE modules. With NORA-W366, designers only need to consider the module
placement and GND clearance in antenna area.
2.5
Data interfaces
NORA-W36 modules have six I/O pins. The pins are assigned to the data interfaces listed below, but
the assignments
can’t
be in conflict. Some GPIO are used for low power modes. For more information,
2.5.1
UART (Universal Asynchronous Receiver Transmitter)
NORA-W36 supports a high-speed UART interface with a maximum baud rate of 6 Mbps. The host
application uses this interface to configure and control the module. Additionally, it can be used to
upgrade the
The UART interface support the following signals:
•
Data lines (
RXD
as input,
TXD
as output)
•
Hardware flow control lines (
CTS
as input,
RTS
as output)
You can use the UARTs in 4-wire mode with hardware flow control, or in 2-wire (default) mode with
TXD
and
RXD
only.
Default interface settings are 115 200 bps, 8 data bits, no parity, 1 stop bit, with no flow control.
☞
To avoid buffer overrun, UART operation in 2-wire mode is not recommended for speeds above
115 200 bps.

General purpose input/output
GPIO_J9
is used as the Deep sleep wake-up signal described in
Two GPIO pins
GPIO SWITCH_1
and
SWITCH_2
are used to enter bootloader, as shown in

If this state is kept for more than 10 seconds without sending
commands to bootloader over UART, the u-connectXpress
application boots. The module settings are then restored to
factory default values.
