Factory Settings:
The module will restore all factory settings if both the SWITCH_1 and SWITCH_0
signals are low during start-up. See the
ODIN-W2 AT Commands Manual [1]
for more information
about the default factory settings.
1.6.5
Firmware update
See the
ODIN-W2 AT Commands Manual [1]
for information about firmware update.

Antenna interfaces
The antenna interface is different for each module version in the ODIN-W2 series.
1.7.1
Antenna connectors
The ODIN-W260 module has two RF antenna U.FL. connectors with a characteristic impedance of 50 ohm. The
main supports both Bluetooth and dual-band Wi-Fi.
The MIMO antenna connector supports 2x2 MIMO 2.4 GHz single band Wi-Fi. The use of multiple antennas at
both the transmitter and receiver improves communication performance. The MIMO technology significantly
increases data throughput. A MIMO m x n system consists of m transmit and n receive antennas, where the data
to be transmitted is divided into m independent data streams.
2x2 MIMO is not supported in the current firmware version.

1.7.2
Internal antenna
The ODIN-W262 module has an internal dual-band PIFA antenna. See Internal antenna design section for
antenna design information.

Data communication interfaces
1.8.1
Universal asynchronous serial interface (UART)
The ODIN-W2 series module provides a Universal Asynchronous Serial Interface (UART) for data communication.
The ODIN-W2 series module can be in configuration mode (Command mode) and data mode. See the
ODIN-W2
AT Commands Manual [1]
for more information about the different module modes.
