3 Electrical interface and connectors
This section describes the signals available on the module interface connectors. There are three ways of connecting:
Via the PCB solder lands on the edge of the PCB, J6 (see figure below: Secondary side connectors). For more information see
Section J6 Solder Lands Description.
Via the 2 x 20-pin 1mm pitch board-to-board (one piece part) connectors J2 and J3. The J2 and J3 connectors exist on the
module only as compression pads (see figure below: Secondary side connectors). These pads mates with the carrier board
one-piece part connector. For more information see Section J2 Connector Description and J3 Connector Description.
Optional:
Via the JST connector, J8 (see figure below: Primary side connectors). The connector is a 6 poles pin header. The pitch is 1mm
and the connector is from JST with part number SM06B-SRSS-TB. For more information see section J8 Connector Description.
3.1 Pin numbering
3.1.1 Primary side connectors
J8 is the JST connector located on the primary side of the module. A1 is the internal antenna.
J4 and J5 are U.FL connectors for external antennas. J4 is the primary antenna connector and J5 the auxiliary antenna connector.
3.1.2 Secondary side connectors

3.3 Characteristics
The cB-0941-02 family is designed to be fully interchangeable with the connectBlue Bluetooth product range. If the host product has
space for the board, it is possible to choose freely between Bluetooth modules, e.g. cB-OEMSPA311i/x or cB-OEMSPA331i/x, or WLAN
modules, e.g. OWSPA311gi/x, without any change of the host product. If you design your power supply for OWS451i/x the modules will
be fully interchangeable.

4.2 External antennas
The external antennas are connected to the module with the on board U.FL connectors. Some antennas are connected directly to
the U.FL connector and some are connected via a U.FL to SMA (cB-ACC-18 or cB-ACC-48) or U.FL to reversed polarity SMA
(cB-ACC-38) adapter cable.
The sections below lists the antennas that are included in the radio type approvals of the module. For each antenna the "Approvals" field
defines in what country/region the antenna is allowed to use. Definitions of the "Approvals" field are:
FCC - The antenna is included in the FCC test reports, and thus approved for use in countries that accept the FCC radio
approvals, primarily US.
IC - The antenna is included in the IC (Industrie Canada) test reports, and thus approved for use in countries that accept the IC
radio approvals, primarily Canada.
R&TTE - The antenna is included in the R&TTE test reports, and thus approved for use in countries that accept the R&TTE radio
approvals, primarily the European countries.
In general, antennas with Reverse Polarity SMA connector or U.FL connector are included in FCC, IC and R&TTE radio tests.
Antennas with SMA connector are not allowed to be used in Canada and USA due to FCC/IC regulations but are in general included in
R&TTE radio tests.
Antennas with a part number in the form "cB-ACC-XX" are available for orders via the connectBlue distribution network.

double row connectors (see section 4.2.1) are not aligned. The outer tangents of the 2.3mm holes align the module if the single row
connectors are used and the inner if double row connectors are used (see Figure 11).
Choose the outer tangent (CC distance 27.24mm) if the module is aligned and mounted with some other technique based on M2 screws
(e.g. press-fit nuts), see Figure 12.

5.2 Using the J2/J3 board-to-board connectors
The board-to-board connector should be a 1 mm pitch one-piece part connector. The recommended manufacture is Samtec with many
connector options available; see section 4.2.1.1.
Chapter 2 contains more information about the connector and the electrical interface.
5.2.1 Suitable one-piece part connectors
5.2.2 Double row ASP-118580-01 / ASP-118581-01 connectors
This connector is a double row connector and connects both J2 and J3. It connector has a height of 3.0 mm and this has to be
considered if components are to be mounted on the motherboard under the board. The connector is also available with a height of 6.0
mm and 10.0 mm (The FSI-120 serie from Samtec).
There are alignment pins on the bottom side of the connector.
The connector is available with M2 threaded inserts (ASP-118580-01) that fit the mounting holes on the board. You may screw the board
directly into these inserts. If you want to have a tighter and more secure mounting you may use longer screws and secure it using a nut
on the backside of the motherboard.
Another way to mount the module is to use press-fit nuts on the motherboard and skip the M2 threads on the connector
(ASP-118581-01), see section 4.3 for more information about press-fit nuts.

5.3 Using press-fit nuts for mounting
A press-fit nut is pressed into the PCB from the bottom side with a special press tool. M2 sized press-fit nuts are suitable for the modules
(see figure below) and are manufactured by PEM Fastening Systems, www.pemnet.com, part no KFS2-M2. Be careful with the distance
between the nuts regarding alignment.
Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used.

5.4 Recommended M2 screw
If a double-row connector with threaded inserts or press-fit nuts are used, then recommended for mounting of modules is a ISO 7380 M2
compatible screw. A suitable screw is the BN6404 from Bossard, www.bossard.com, with TORX T6 head cap. See figure below.

If other type of screw is used please ensure that d2 is less than 3.8 mm otherwise components near the mounting holes
can be damaged.
5.5 Antenna issues
The unit cannot be mounted arbitrary, because of the radio communication. The unit with an internal surface mounted antenna cannot be
mounted in a metal enclosure. No metal casing or plastics using metal flakes should be used, avoid also metallic based paint or lacquer.
Keep a minimum clearance of 10 mm between the antenna and the casing. Keep 10 mm free space from metal around the antenna. If a
metal enclosure is required, one of the external antenna options has to be used. See section 3.2 for more information on the antenna
options available.
