Wireless Module Product Description R100H The Lora RF module R100H offered by NETVOX is low power consumption transceiver based on the SX1276 chip LoRaTM solution. The R100H is designed to be SMD-mounted onto a host PCB. SMD-mounting provides the best RF performance at the lowest cost. Additionally the R100H is designed to occupy minimal board space on the host PCB, which already includes plentiful interfacing ports and power management circuits. So it can be easily integrated into other device without the need for RF experience and expertise. The R100H operates in the 862-1020MHz band. Applications Automated Meter Reading Home and Building Automation Wireless Alarm and Security Systems Industrial Monitoring and Control Long range Irrigation Systems

Wireless Module R100H Mechanical Drawing and Dimensions Figure 4 Mechanical Drawing and Dimensions The module size is 16.0*24.5*3.0mm Antenna and Range Considerations The radiation pattern from the antenna is similar The R100H 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. 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 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.

Wireless Module PCB Layout Recommendations R100H 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. Figure 5 R100H/L PCB Layout dimension
