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.

5 Mounting information

5.1 Module dimensions

connectBlue

Tolerances:

Outline dimensions +/- 0.1mm

Drilled hole to outline: +/- 0.05mm

5.1.1 Mounting holes

There are 2 x 2.3mm mounting holes on cB-0942. The reasons for the 2.3mm holes are that the threaded M2 holes on the single and

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.

connectBlue

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.

the connectBlue global quote number for best price. For technical questions regarding the Samtec connectors please

contact connectBlue or Samtec at Scandinavia@samtec.com.

See figure below for more information about the connector and necessary measurements on the motherboard. The large mounting holes

on the motherboard are designed for press-fit nuts and could be smaller if press-fit nuts are not used.

connectBlue

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, , part no KFS2-M2. Be careful with the distancewww.pemnet.com

between the nuts regarding alignment.

Spacer-pipes are recommended to use between the PCBs when press-fit nuts are used.

connectBlue

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, , with TORX T6 head cap. See figure below.www.bossard.com

Parameter Value Unit

d2 3.5 mm

k max 1.3 mm

t max 0.8 mm

A 2.0 mm

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.
