RF Transceiver Modules And Modems Procurement Notes

Verify the specific suffix RM140 confirms the inclusion of the integrated ceramic antenna and shielding. Confirm the voltage grade 'V' aligns with the required 3.3V operational environment. Check RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure UART pinout compatibility with the target microcontroller interface.

RF Transceiver Modules And Modems Selection Notes

Select this model when an integrated antenna solution is preferred over external PCB traces. The shielded enclosure reduces electromagnetic interference susceptibility. The UART ASCII interface simplifies firmware development compared to binary protocols. Consider the fixed 0 dBm output power for short-range applications requiring minimal RF design effort.

RF Transceiver Modules And Modems Part Context

This component belongs to the RN4870/71 series of Bluetooth modules by Microchip Technology. It is designed for low-power wireless connectivity in compact electronic devices. The module integrates the RF transceiver, baseband processor, and antenna into a single surface-mount package. It serves as a drop-in replacement for more complex custom RF designs.

RF Transceiver Modules And Modems Replacement Considerations

RN4871-I/RM140 offers similar functionality with an extended industrial temperature range of -40°C to +85°C. RN4871U-V/RM118 provides a variant without an integrated antenna, suitable for designs requiring external antenna placement.
