Product Information

The Wireless Module R109H is a low power consumption transceiver based on the SX1262 chip LoRaTM solution. It is designed to be SMD-mounted onto a host PCB, providing the best RF performance at the lowest cost. The module operates in the 902-928MHz band and is suitable for various applications.

Product Description

The Lora RF module R109H offered by NETVOX is low power consumption transceiver based on the SX1262 chip LoRaTM solution. The R109H is designed to be SMD-mounted onto a host PCB. SMD-mounting provides the best RF performance at the lowest cost. Additionally the R109H 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 R109H operates in the 902-928MHzMHz band.

Mechanical Drawing and Dimensions

• The module size contains no antenna is 16.0*24.5*3.0mm
• The module size contains an antenna is 16.0*29*8.0mm(Just for reference)

Antenna and Range Considerations
The R109H 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 one 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 RF input/output is matched to 50 Ohm.

PCB Layout Recommendations

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 onboard 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.

For in circuit programming and debugging, the 10 pin interface (as following figure ) must be reserved in the mainboard PCB.

The 10 PIN respectively connects the module’s PIN. Please see the table below for the detail.

FCC

FCC Statement:
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:

1. This device may not cause harmful interference, and
2. this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarant ee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.

Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

IC Statement:
This device complies with Industry Canada’s license-exempt RSSs. Operation is subject to the following two conditions:

1. This device may not cause interference; and
2. This device must accept any interference, including interference that may cause
