ABBTM-NVC-MDCS71-MESH is a single-mode Bluetooth v4.1 low power module based on CSR’s CSR1010. By integrating CSRmesh

and Novacomm’s proprietary technologies into the single module, it provides a simple solution for building intelligent network so devices can

communicate with each other directly.

CSRmesh supports different device models. Current firmware combines light model (e.g. LED lights) and data model together. It allows the

module to be used in a color LED light, or as a network endpoint to transmit data to each other. The module uses an ASCII command interface

over its 2 wire UART port. The command details can be found in the Software Interface for Mesh Application Manual.

Current firmware allows the module to scan for data packets from nearby devices and relay the data if needed. It consumes approximately

20mA @3V, so it is suitable for applications with power supply connected. If low power consumption operation mode is needed, please

contact Abracon for custom firmware.

LAYOUT AND SOLDERING

RoHS/RoHS II compliant

19.5 x 12.5 x 2.4 mm SMT

Soldering Recommendations

ABBTM-NVC-MDCS71 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile

used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular

type of solder paste used. Please refer to the datasheet of the particular solder paste for profile configurations.

The following are recommended for soldering the module to ensure reliable solder joint and operation of the module

after soldering. Since the profile used is process and layout dependent, the optimum profile should be studied case by

case. Thus following recommendation should be taken as reference only.

• Refer to technical documentations of particular solder paste for profile configurations

• Avoid using more than one flow.

• Reliability of the solder joint and self-alignment of the component are dependent on the solder volume. Minimum of

150µm stencil thickness is recommended.

• Aperture size of the stencil should be 1:1 with the pad size.

• A low residue, “no clean” solder paste should be used due to low mounted height of the component.

Figure 5. Typical Lead-Free Reflow Solder Profile for ABBTM-NVC-MDCS71

Key features of the profile:

•

Initial Ramp = 1-2.5°C/sec to 175°C ±25°C equilibrium

•

Equilibrium time = 60 to 180 seconds

•

Ramp to Maximum temperature (250°C) = 3°C/sec max.

•

Time above liquidus temperature (217°C): 45-90 seconds

•

Device absolute maximum reflow temperature: 255°C

Layout Guideline

It is strongly recommended to use good layout practices to ensure proper operation of the module. Placing copper or any

metal near antenna deteriorates its operation by having effect on the matching properties. Metal shield around the

antenna will prevent the radiation and thus metal case should not be used with the module. Use grounding vias separated

maximum 3 mm apart at the edge of grounding areas to prevent RF penetrating inside the PCB and causing an

unintentional resonator. Use GND vias all around the PCB edges. Figure 4 illustrates recommended PCB design around

the antenna of ABBTM-NVC-MDCS71 when the module is placed at the edge of a PCB.

Do not place copper on the top layer under the module, as shown in Figure 6. The module has vias on the area shown,

which can cause short circuit if there is copper underneath. Any metal placed closer than 20 mm in any direction from

the antenna changes the matching properties and thus will considerably deteriorate the RF performance of the module.
