1 Introduction
1.1 OVERVIEW
The IEEE 802.15.4 OEM Module, cB-OZS311, from connectBlue
has been developed for integration in industrial devices
providing state of the art low power features. The module
minimizes the work needed to implement IEEE 802.15.4 in a
device as it provides all software, hardware, type approval, EMC
certification etc. It is developed for reliable, high demanding
industrial devices and applications and requires no host driver.
The cB-OZS311 module is available in different versions and are
all based on the PCB cB-0922-02 (see section 1.4).
The cB-OZS311 module is a complete IEEE 802.15.4
implementation. No external driver is needed. The IEEE 802.15.4
module has a small form factor and the interface layout is the same as the Bluetooth and
Wireless LAN modules from connectBlue, which enables customers to prepare their device for
both IEEE 802.15.4, Bluetooth and/or Wireless LAN.
1.2 KEY FEATURES
• No software driver needed.
• Radio type approved for Europe.
• Unlicensed Modular Transmitter Approval for US (FCC) and Canada (IC).
• Compliant with EMC standards.
• Industrial temperature range -40 to +85 °C.
• Support for low power modes.
• Compatible with connectBlue Bluetooth and Wireless LAN modules
• Supports security AES128 encryption
• Internal or external antenna

2 Electrical Interface and Connectors
2.1 OVERVIEW
This section describes the signals available on the module interface connectors.
There are three ways to connect to the OEM Serial Port Adapter:
• Via the PCB solder pads on the bottom side of the PCB, J6 (see Picture 2). See Section
5.4 for more information.
• Via the 2x20-pin 1mm pitch board-to-board (one piece part) connectors, J2 through J3.
The J2 to J3 connectors on the OEM Serial Port Adapter exist on the module only as a
mating PCB-layout pattern (see Picture 3). See Section 5.2 for more information.
• Via the optional JST connector, J8 (see Picture 4). The connector is a 6 poles wire
connector. The pitch is 1mm. The connector is from JST with part number SM06B-SRSS-
TB.
The cB-OZS311x models have also an external coaxial antenna connector (see Picture 5).
Picture 2: J6 are available on the edge of module. Picture 3: J2 to J3 are available on module.
Picture 4: JST 6-pol connector, J8. Picture 5: External antenna connector.
