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.

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 150m 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.

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. Figure 6.
