RF Transceiver Modules And Modems Procurement Notes

Verify the specific suffix 'R' indicates tape and reel packaging when sourcing components. Confirm that the 868MHz variant aligns with regional regulatory requirements for your target market. Ensure the host system provides the necessary SPI interface signals and operates within the specified 1.8V to 3.6V supply voltage range. Cross-reference the manufacturer part number with distributor listings to ensure availability of the correct package type.

RF Transceiver Modules And Modems Selection Notes

Select this module for applications requiring long-range communication in the 868 MHz ISM band. It is suitable for low-power IoT devices needing high receiver sensitivity. Consider the SX1272 chip's capabilities if FSK or OOK modulation is also required alongside LoRa. Ensure the design accommodates the physical dimensions and thermal requirements for the operating temperature range of -20°C to +70°C.

RF Transceiver Modules And Modems Part Context

This component belongs to the RFM95W series of LoRa transceiver modules. These modules are designed for low-power wide-area network (LPWAN) applications. The series typically includes variants for different frequency bands such as 433 MHz and 915 MHz. The RFM95W designation generally implies compliance with CE regulations for European markets.

RF Transceiver Modules And Modems Replacement Considerations

Public confirmed substitute part numbers include RFM95W-868S2 and RFM95-868S2R. These parts share the same core SX1272 functionality and form factor. Verify that any replacement matches the specific 868 MHz frequency band and packaging configuration required by the assembly process.
