1 Integrated Devices and Block Diagram 1.1 Module Block Diagram The module has been optimized for minimum costs in lighting applications as a primary design goal. Therefore the list of peripheral devices is rather short with only a serial FLASH memory. Figure 1-1 shows the block diagram for the module. The harmonic filter is purely capacitive and the antenna is integrated on the PCB. Beside some test points, the module interface is providing five GPIO lines only. See section 3 for detailed information.

2 Mechanical Description If not otherwise noted a tolerance of 0.1mm shall be considered for all dimensions. 2.1 Mechanical Dimensions The module pins are arranged with a 2mm pitch distance. Figure 2-1 shows the actual dimensions and pin locations within the module design. Figure 2-1. Module Bottom dimensions, seen from a CAD top perspective The module can be solder mounted directly to a base board. Provision is made for direct SMT mounting and for true hole mounting on a pin header with 2mm pitch.
PAGE 6
2.3 Footprint Recommendation Since the antenna is integrated, a number of design constraints have to be considered for the base board design. 2.3.1 Pin header mounting The module can be mounted on pin headers with 2mm pitch like the SAMTEC TMM series. This mounting scheme requires a 7-pin single row header and two single pins next to the antenna. The pins are supposed to be assembled on the base board in the normal top assembly process.
PAGE 7
2.3.2 Surface solder mounting For lowest cost, the module can be surface mounted to the base board. This saves the costs for the pin header. The drawing in Figure 2-3 shows the recommended base board foot print. The antenna shall not be influenced by the base board material. Any metal or dielectric material as FR-4 or similar would tune the antenna out of band. The module has to be mounted with the antenna end to protrude beyond the board edge.

3 Module pin assignment 3.1 Application pins The module pin assignment is shown in Table 3-1 Table 3-1. The Column “uC pin” is a reference to the ATSAMR21 datasheet (SAMR21). The column “Pin function” shows a selection of alternative IO functions. Please refer to the ATSAMR21 datasheet for the complete IO multiplexer description.
PAGE 9
3.2 Test points For test and development use, the module is equipped with a number of test points. The bottom test points are easy accessible in conjunction with the module development tool. The top test points can be probed while the module is installed on the final application board. 3.2.1 Top layer test points The test points on top layer can be used as a debug serial interface or as GPIO. Figure 3-1 shows the test point locations while the test point function is documented in Table 3-2.
PAGE 10
Figure 3-2. 3.3 Bottom layer test point locations Antenna Ground Reference To achieve the specified performance the antenna requires the ground plane of a base board as a reference plane for the outgoing field. See section 2.3 for detailed design recommendations. When the module needs to be operated without a base board e.g. for debugging two 40mm wires can be soldered to the antenna ground pins as a makeshift ground plane. Figure 3-3.
