RNBD350UE-I100 개요
A Bluetooth Low Energy (BLE) module is a complete radio subsystem that implements the Bluetooth LE protocol stack, RF front end and antenna matching in a certified package, sitting within the hierarchy of wireless connectivity ICs: transceiver module -> RF transceiver -> radio IC -> semiconductor device. Unlike a chip antenna or a discrete radio design, a certified module such as the RNBD350UE requires no RF design work and no additional regulatory certification by the end-product manufacturer.
Key features include true plug-and-play operation with no firmware programming required, communication with a host MCU or MPU over a Two-Wire or Four-Wire (flow-control) UART interface using Microchip's simple ASCII command set, and support for Bluetooth 5.2 features including 2 Mbps PHY, Data Length Extension (DLE) and LE Secure Connections, which are enabled by default for encrypted pairing resistance against passive eavesdropping.
At its core, the RNBD350 module is based on Microchip's PIC32CX-BZ3 Bluetooth Low Energy System-on-Chip (SoC), which integrates the BLE radio, protocol stack and processing in a single silicon solution, providing a complete connectivity implementation in a pre-certified form factor. This architecture offloads all BLE stack management from the host, so the host processor only needs to parse simple ASCII commands.
Typical applications include adding BLE connectivity to industrial sensors and actuators, smart-home and IoT end nodes, and embedded systems where the host MCU has no native radio. Because the module is plug-and-play, a design team can add certified Bluetooth LE connectivity in days rather than months.
A key design consideration: since the U.FL antenna connector means the antenna is external, place the U.FL receptacle and its mating cable route away from switching-regulator components to preserve RF sensitivity, and ensure the host UART baud rate matches the module default configuration.

일반적인 애플리케이션
RNBD350UE-I100 적합 용도: 6 애플리케이션s: Industrial Sensor and Actuator Connectivity, Smart Home and IoT End Nodes, Medical and Health Monitoring Devices, Retrofit Connectivity for Existing Embedded Products, Point-of-Sale and Beacon Infrastructure, Prototype and Education Platforms.
Industrial Sensor and Actuator Connectivity
The RNBD350UE-I100 adds certified Bluetooth 5.2 Low Energy connectivity to industrial sensors, actuators and HMI nodes without firmware development. Because it is controlled entirely through Microchip's ASCII command set over a Two-Wire or Four-Wire UART, an existing PIC, AVR, SAM or even Linux-based host can advertise, pair and stream data with simple text commands - no BLE stack porting required. Its 1.9 V to 3.6 V supply range fits a standard 3.3 V rail, and the U.FL antenna connector lets engineers position the antenna on a metal enclosure for optimal RF propagation, which an integrated PCB antenna cannot do. LE Secure Connections (enabled by default) provides encrypted pairing against passive eavesdropping, essential on factory floors.

Smart Home and IoT End Nodes
For smart-home devices - door locks, thermostats, lighting controllers and appliance nodes - the RNBD350UE-I100 delivers BLE 5.2 with 2 Mbps PHY and Data Length Extension, which increases BLE packet PDU length for higher throughput during firmware updates and bulk data sync. The module requires no programming and no additional regulatory certification, dramatically cutting time to market for consumer IoT products where certification schedules dominate launch dates. The U.FL interface accepts a wide range of external antennas to tune range for whole-home coverage, and the pre-certified shielded module keeps EMC design risk low. Host microcontrollers as small as 8-bit devices can drive it over UART, keeping BOM cost minimal.

Medical and Health Monitoring Devices
Battery-powered health monitors - pulse oximeters, glucose meters, activity trackers - benefit from the RNBD350UE-I100's 1.9 V to 3.6 V supply range, directly compatible with single-cell lithium and coin-cell power architectures. BLE 5.2 LE Secure Connections, enabled by default on this module, encrypts pairing to protect sensitive patient data from passive eavesdropping, addressing a core privacy requirement in medical connectivity. The ASCII command interface means the device's host MCU spends no cycles running a BLE stack, extending battery life by keeping the host in sleep between measurements. The U.FL antenna connector supports compact wearable enclosures with an external antenna tuned for body-worn RF conditions.

Retrofit Connectivity for Existing Embedded Products
The RNBD350UE-I100 is purpose-built for retrofitting BLE connectivity onto products whose host firmware is already frozen or hard to modify. Because the module is truly plug-and-play - no programming, no RF design, no regulatory certification per Microchip - a design team can add a UART port and this module to an existing PCB and ship Bluetooth capability within weeks. The Two-Wire UART option uses just TX and RX lines, minimizing board changes, while Four-Wire flow control (RTS/CTS) protects against data loss at higher throughput with DLE-enabled 2 Mbps links. The 13.4 x 18.7 mm shielded module fits into most existing enclosure outlines without RF re-layout.

Point-of-Sale and Beacon Infrastructure
BLE beacon tags, asset trackers and point-of-sale peripherals use the RNBD350UE-I100's configurable advertising and connection-oriented modes driven over the ASCII UART interface. Data Length Extension raises packet PDU length for faster data bursts, useful when syncing transaction logs or sensor history in bulk, and the 2 Mbps PHY shortens radio-on time to conserve power in duty-cycled devices. Operating from 1.9 V to 3.6 V, the module runs directly from lithium primary cells in asset tags. The pre-certified shielded module and U.FL external-antenna option let installers adapt RF coverage per site - wall-mounted readers, ceiling beacons, or metal-cabinet trackers - without respinning radio hardware.

Prototype and Education Platforms
Universities, makers and product-development teams use the RNBD350UE-I100 as the fastest route to a working BLE 5.2 link: pair it with the low-cost Microchip EV65D15A RNBD350 add-on board and a USB-UART bridge, and a laptop terminal can send ASCII commands to scan, connect and exchange GATT data within minutes. Because the module needs no programming or BLE stack knowledge, it is ideal for teaching wireless protocol concepts and for hardware teams validating mechanical enclosures before committing to RF design. The U.FL connector supports swapping antennas during characterization, and the same footprint transitions directly from breadboard-adapter prototypes to production PCBs.

설계 노트
Because the RNBD350UE-I100 uses a U.FL connector instead of an onboard antenna, keep the U.FL receptacle at the board edge with a short, impedance-controlled feed and route the antenna cable away from switching regulators, crystals and high-speed digital lines. The module itself is shielded, so internal digital circuitry does not desensitize the receiver, but cable placement relative to ground planes and metal enclosure walls directly affects radiation efficiency. Microchip's RNBD350 user guide (DS50003684) should be consulted for modular-certification antenna requirements before finalizing the mechanical design.
Supply the module from a clean 1.9 V to 3.6 V rail; a 3.3 V LDO output is the standard choice. BLE radios draw pulsed transmit current bursts, so place at least 10 uF of bulk capacitance plus 0.1 uF of ceramic decoupling close to the module supply pins to prevent rail droop during TX bursts, which can cause reset or degraded sensitivity. If the host MCU runs at 5 V, level-shift the UART lines - the module I/O must not be driven above its supply domain. Estimated: at 3.3 V with typical BLE burst currents, a 100 mV droop budget implies low-impedance decoupling is mandatory.
The module's UART is the only control path - verify the default baud rate documented in the RNBD350 datasheet (DS70005561) before writing host code, and implement the Four-Wire (RTS/CTS) flow-control option in new designs to prevent FIFO overflow when Data Length Extension enables higher throughput. DLE and LE Secure Connections are enabled by default; do not disable them casually, as DLE-off reduces throughput and unsecured pairing exposes the link to passive eavesdropping. Prototype on the EV65D15A add-on board before committing to a custom PCB layout.
