What are the key features of RN42N-I/RM?

Integrated Bluetooth 2.1+EDR radio with onboard antenna in a compact 35-pin module assembly
3 V to 3.6 V supply voltage operation enabling direct 3.3 V system integration without level shifting
Serial port profile (SPP) support for transparent wireless UART replacement in embedded designs

What is RN42N-I/RM used for?

The RN42N-I/RM Bluetooth module enables rapid wireless connectivity integration for embedded systems, medical devices, and industrial data loggers without requiring custom RF design. Its 3 V to 3.6 V supply range allows direct connection to 3.3 V microcontrollers for serial data streaming over Bluetooth 2.1. The compact 35-pin module assembly simplifies FCC/CE regulatory compliance since the module carries pre-certified RF approval.

Frequently Asked Questions

What supply voltage does the RN42N-I/RM require and can it connect directly to 3.3 V microcontrollers?

The RN42N-I/RM operates from 3 V to 3.6 V, making it directly compatible with 3.3 V microcontroller systems without voltage level translation on the UART lines. This simplifies PCB design when pairing with common ARM Cortex-M or PIC microcontrollers that use 3.3 V I/O, reducing component count compared to 5 V Bluetooth modules.

Which Bluetooth profiles does the RN42N-I/RM support for industrial serial data applications?

The RN42N-I/RM supports Bluetooth 2.1+EDR with Serial Port Profile (SPP), which creates a transparent wireless UART link between embedded devices. SPP mode allows the module to replace a physical UART cable with a wireless connection up to approximately 10 meters (Class 2 radio), ideal for industrial data loggers, barcode scanners, and wireless sensor nodes.

What is the lead time for RN42N-I/RM and what package type does it use?

The RN42N-I/RM has a factory lead time of 12 weeks and uses a rectangular 35-pin microelectronic assembly (MODULE-35) package. This module assembly style integrates RF components including antenna on a small PCB module, simplifying the host PCB design and reducing the engineering effort needed to pass RF regulatory certification for Bluetooth emissions.

When should designers choose RN42N-I/RM over discrete Bluetooth chip solutions for product development?

The RN42N-I/RM is preferable when time-to-market matters more than unit cost, because the 35-pin module includes an integrated antenna, RF matching network, and pre-certified firmware, eliminating up to 40 external passive components. For production volumes under approximately 10,000 units, the engineering savings from not designing a custom 3 V Bluetooth RF front-end typically outweigh the higher module cost.
