Page 5: System Description
ODIN-W2 series - System Integration Manual 1 System description The ODIN-W2 series is a highly integrated multiradio module developed by u-blox for integration in demanding, reliable devices such as those needed for industrial and medical applications. The module is built around a multiradio chip, which includes Wi-Fi, Classic Bluetooth and Bluetooth Low Energy (Dual Mode / Bluetooth Smart Ready). -
Page 6: Architecture
Different antenna options are available depending on the chosen ODIN-W2 series model: • ODIN-W260: A standard coaxial U.FL. connector that must be connected to an external antenna through a coaxial cable. See Antenna connectors section for more information about the antenna connectors. -
Page 7: Pin Description
ODIN-W2 series - System Integration Manual The power management is handled by a 1.8 V DC regulator that supplies the host core and IOs. The 1.8 V IO voltage is also available on the solder pads for use on an external interface logic. The 1.8 V is always available if the VCC supply to the module is stable. - Page 8 ODIN-W2 series - System Integration Manual Function Name Description Remarks Ground All GND pads must be connected to ground. System RESET_N External reset input. Internal active pull-up to V_INT. Logic Red LED Signal. Active low. GREEN/SWITCH_1 Logic Green LED Signal. Active low.

ODIN-W2 series - System Integration Manual 1.6 System function interfaces 1.6.1 Module reset You can reset (reboot) the ODIN-W2 series modules using one of the following methods: • Hardware reset: Low level on the RESET_N pin, which is normally set high by an internal pull-up, for a valid time period (see ODIN-W2 series Data Sheet [2]). -
Page 11: Firmware Update
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. -
Page 12: Ethernet (Rmii+Smi)
ODIN-W2 series - System Integration Manual The following UART signals are available: • Data lines (RXD as input, TXD as output) • Hardware flow control lines (CTS as input, RTS as output) The UART can be used as both 4 wire UART with hardware flow control and as 2-wire UART with only TXD and RXD. - Page 13 ODIN-W2 series - System Integration Manual The following two types of ground (GND) pads are available: • GND pads and the PCB edge (castellations): Mainly for power supply return path and RF ground. • Heat dissipation GND pads under the module: Mainly used for dissipation of heat, especially during intensive Wi-Fi activity.
