Key Features
- Bluetooth 5.0 Low Energy support with integrated antenna and BLE stack reduces host MCU firmware complexity for IoT sensor and wearable designs
- 1.9 V to 3.6 V supply voltage range is compatible with single-cell LiPo and CR2032 coin-cell battery systems for ultra-low-power wireless nodes
- 16-pad MODULE SMT package (R-XXMA-N16) with seated height optimized for thin-profile wearable and asset-tracking PCB assemblies
Applications
The RN4871-I/RM128 is suited for wireless sensor nodes, wearable health monitors, and industrial asset-tracking tags where low-power BLE 5.0 connectivity is required with minimal host processor overhead. Its integrated stack and AT command interface allow a simple UART-connected microcontroller to exchange data with smartphones and gateways without implementing the full Bluetooth protocol. The module also fits smart home accessories, beacon transmitters, and proximity sensors operating from coin-cell batteries that must meet FCC and CE regulatory requirements without separate RF certification testing.

Frequently Asked Questions
What supply voltage range does the RN4871-I/RM128 support and which battery chemistries are directly compatible?
The RN4871-I/RM128 operates from 1.9 V to 3.6 V, covering the full discharge curve of CR2032 lithium coin cells (3 V nominal, down to 2 V end-of-life), single-cell LiPo batteries (4.2 V charged, 3 V nominal, but used with a small LDO), and AAA alkaline cells in series. This range means the module can run directly from a coin cell across its entire useful life, reducing the BOM to the module, battery, and a handful of bypass capacitors for a complete 2-wire BLE node.
How does integrating the BLE 5.0 stack inside the RN4871-I/RM128 simplify firmware development compared to a discrete radio IC?
With the full BLE 5.0 protocol stack, GATT profiles, and AT command parser built into the RN4871-I/RM128, the host MCU only needs to send simple ASCII commands over a UART at 115200 baud to advertise, connect, and transfer data. A discrete radio IC such as a raw 2.4 GHz transceiver requires the host to implement all L2CAP, ATT, GATT, and GAP layers in firmware, typically adding 50 kB to 100 kB of flash and weeks of BLE stack integration effort.
For a certified IoT product, what regulatory advantage does using the RN4871-I/RM128 module provide over designing a custom BLE radio?
Microchip's RN4871-I/RM128 is a pre-certified modular transmitter, meaning designs that use it as a complete RF sub-system can leverage Microchip's existing FCC modular grant and may qualify for expedited or reduced-scope regulatory testing rather than a full FCC Part 15 radio certification which can take 8 weeks to 16 weeks and cost $15,000 or more. This time and cost savings is especially significant for startups or low-volume industrial products that cannot absorb a full RF regulatory program before market launch.
