Mechanical Drawing and Dimensions - 7- Wireless LoRa Module 16mm R107H 24.5mm Figure 4 Mechanical Drawing and Dimensions The module size is 24.5*16*2.5mm Antenna and Range Considerations The R107H module is delivered with an integrated antenna. This is highly recommended for most applications, as this gives a very compact solution containing all the critical RF parts within the module. The radiation pattern from the antenna is similar to the donut-shaped obtained from a quarter wave antenna. That is, the maximum radiation is in the plane perpendicular to the length axis of the antenna. For best achievable radiation the module should be oriented so that the antenna is vertical. The antenna should be kept more than 10 millimeters away from metallic or other conductive and dielectric materials. Any metallic - 8- Wireless LoRa Module R107H enclosures would shield the antenna and reduce the communication range drastically. In applications where the module must be placed in a metallic enclosure, an external antenna would give best signal strength. The external antenna is attachable from the i-PEX connector . The RF input/output is matched to 50 Ohm. PCB Layout Recommendations The figure 5 shows the proper layout footprint for the module. The footprint shown by figure 6 is also fit for the PA module offered by NETVOX. The area underneath the module should be covered with a solid ground plane. And for greater flexibility and compatibility, the footprint shown by Figure 6 is strongly recommended to use. Each ground pin should be connected directly to the ground plane. In case the ground plane is on an inner layer of the PCB, via should be placed as close as possible to every ground pad of the module to create low impedance grounding. Unconnected pins should be soldered to the pads, and the pads should be left floating. When using the module with on-board ceramic chip antenna lying on the north-east corner of the module, the area underneath the antenna should be kept open, and if possible extended in east and north direction as far as possible. Best possible placement of the module on your main PCB is in the far north-east corner. Positioning to suit different application please refer to the figure 7. - 9- Wireless LoRa Module 16mm R107H 24.5mm Figure 5 R107H PCB Layout dimension - 10 - Wireless LoRa Module R107H Figure 6 Suggested Module Footprint Layout Figure 7 Module mounting position For in circuit programming and debugging, the 10 pin interface (as following figure ) must be reserved in the mainboard PCB. - 11 - Wireless LoRa Module R107H 10 PIN debug interface footprint The 10 PIN respectively connects the module's PIN.
