RFM210LB-S1 OOK General Description of RFM95C RFM95C is an ultra-low-power, high-performance LoRa transceiver for various frequency of 137-1020 MHz wireless applications. It is part of the SEMTECH RF product line, which includes complete transmitters, receivers and transceivers. The high integration of RFM95C simplifies the peripheral materials needed in the system design. The sensitivity up to - 138 dBm which can optimize the link performance of applications.In addition, RFM95C also supports Duty-Cycle operation mode, channel intercepti on, high-precision RSSI, power-on reset, noise output and other more functions, which makes the application design more flexible thus to achieve product differentiation design. The working voltage of RFM95C RFM95C is 1.8V~3.7V. When the sensitivity is reaching
-138 dBm, it only consumes 9.9 mA current. This ultra-low power mode can further reduce the power Ordering Information Model No. Working Frequency RFM95C 915MHz consumption of the chip. Features Frequency Range: 915MHz Modulation: LoRa Sensitivity: -138 dBm , BW=500KHz, SF=12 Voltage Range: 1.8~3.7 V Receiving Current: 12.5 mA Supports Ultra Low Power Receiving Mode 4-wire SPI Interface Supports Full-automatic Independent Working Mode E-mail:sales@hoperf.com Rev1.0 www.hoperf.com Applications RFM95C B Intelligent Instrument ISM Band Data Communication Industrial Monitoring & Controlling Automatic meter Reading Home Security&Building automation Security System Remote Control Application Supply Chain & Logistics Smart City Retailing Asset Following Smart Lighting System Smart Parking Environmental Monitoring Health Monitoring Intelligent Agriculture Product Pin Bottom View of RFM95C E-mail:sales@hoperf.com Rev1.0 www.hoperf.com Table1.

Please pay attention to the installation direction (pin direction). FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. 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 device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. NOTE:
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 guarantee 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. FCC ID: 2ASEORFM95C E-mail:sales@hoperf.com Rev1.0 www.hoperf.com ATTENTION RFM95C B This device is intended only for OEM integrators under the following conditions:
