User guide
1 General Description
The OZMO2000WM014 Wireless Module is
a fully assembled and tested generalpurpose module using the OZMO2000
wireless System-on-Chip (SoC). The module
contains the OZMO2000 chip, memory,
antenna, and all other necessary
components to operate the OZMO2000.
The memory is preloaded with firmware that
is compatible with Windows 7 SoftAP or WiFi CERTIFIED™ Wi-Fi Direct host systems.
With modified firmware, the OZMO2000 can
support other interfaces, such as I2C and
GPIO. Contact your Ozmo FAE for
assistance with these interfaces.
For detailed information on the OZMO2000
component itself, refer to the OZMO2000
datasheet.
2 Features
Small, self-contained SMT module
On-board memory stores OZMO2000
program image, MAC address and security
credentials
On-chip regulators allow direct connection to
battery or unregulated supply between 1.8V
and 3.6V. ( certain limitations may apply
depending on module version )
Total module height is 4mm
3 Benefits
On-board 8051 processor eliminates need
for external micro-controller.
Flexible application interfaces included: I2C,
PCM/I2S, GPIOs, LED drivers with PWM.
Great battery life thanks to low power radio
and systems design.
Low latency thanks to agile systems
architecture and fast wake up algorithms.

5.2 Using the module
The WM014 module is designed to operate with customized embedded firmware programmed
into the module by Ozmo Devices which controls the functioning of the radio and the various
interfaces.
The General Purpose Input-Output pins (referred to as AIO or GPIO pins) are configured and
monitored by the firmware.
Depending on the programmed functionality, the module will send data over the wireless link
corresponding to the inputs received on the AIO pins, or will output digital signals from the AIO
pins based on data received over the wireless link.
Ozmo application engineers will work with customers to define the desired Input-Output behavior
and develop the customized firmware to achieve the desired digital input-output behavior. This
has no effect on the radio operation which is defined by low-level firmware and hardware and
always operates in accordance with FCC and Wi-Fi standards. The custom aspects of the
firmware only affect the formatting and timing of the back-end digital I/O functions.
