RF Transceiver Modules And Modems Procurement Notes

Verify the specific firmware version and protocol support against the latest official datasheet before integration. Confirm that the unshielded design meets electromagnetic compatibility requirements for the target application environment. Ensure the host system provides stable voltage within the 1.9 V to 3.6 V range to maintain reliable operation.

RF Transceiver Modules And Modems Selection Notes

Select this component when a cost-effective, unshielded BLE solution is required for space-constrained designs. It is suitable for applications where external antennas are preferred or already present. Consider the RN4870-V variants if internal shielding or integrated antennas are necessary for improved RF performance.

RF Transceiver Modules And Modems Part Context

This module belongs to the RN4870 family of Bluetooth Low Energy transceivers from Microchip Technology. It shares core architectural similarities with the shielded RN4870-V series but differs in physical construction by omitting the metal shield and onboard antenna. This variant offers flexibility for custom antenna integration while maintaining standard UART compatibility.
