What are the key features of RN4678-V/RM122?
- Dual-mode Bluetooth 4.2 BLE and Bluetooth 2.1+EDR in a single 33-pin module
- Ultra-low 1.8 V to 2.1 V supply voltage for direct integration with low-voltage SoCs
- Simple UART ASCII command interface eliminates Bluetooth stack software development
- FCC/IC/CE certified module reduces regulatory certification burden for end products
- Compact rectangular microelectronic assembly enabling space-efficient wireless designs
What is RN4678-V/RM122 used for?
The RN4678-V/RM122 is used in IoT devices, medical wearables, and industrial wireless adapters where both Bluetooth Classic and Bluetooth Low Energy connectivity are needed in a single certified module. Its UART command interface allows host MCUs operating at 1.8 V to 2.1 V to add wireless functionality without implementing a Bluetooth stack. The module is also popular in point-of-sale terminals, smart home gateways, and asset tracking devices requiring certified dual-mode Bluetooth with short development timelines.

Frequently Asked Questions
What Bluetooth standards does RN4678-V/RM122 support and what supply voltage does it require?
The RN4678-V/RM122 supports both Bluetooth 4.2 BLE and Bluetooth 2.1+EDR classic profiles simultaneously, operating from a narrow 1.8 V to 2.1 V supply voltage, making it suitable for dual-mode wireless connectivity in low-voltage embedded systems requiring 33-pin module integration.
How does RN4678-V/RM122's UART interface simplify adding Bluetooth to a host MCU design without a software stack?
The RN4678-V/RM122 exposes all Bluetooth functionality through a UART ASCII command interface, allowing host MCUs to initiate connections, send data, and configure profiles using simple text commands over 1.8 V to 2.1 V logic-level serial lines without writing any Bluetooth protocol stack code.
For a medical wearable requiring certified wireless, how does RN4678-V/RM122 reduce regulatory approval time compared to a discrete Bluetooth IC?
The RN4678-V/RM122 is pre-certified for FCC, IC, and CE regulatory requirements, enabling medical wearable designers to use modular certification rather than full device certification, potentially reducing regulatory approval timelines by several months at 1.8 V to 2.1 V operation with 33-pin mounting.
Is RN4678-V/RM122 backward compatible with Bluetooth 2.1 Classic devices such as legacy barcode scanners or audio headsets?
Yes, the RN4678-V/RM122 supports Bluetooth 2.1+EDR Classic in addition to Bluetooth 4.2 BLE, allowing it to pair with legacy Bluetooth Classic peripherals like barcode scanners, SPP serial adapters, and audio accessories from a 1.8 V to 2.1 V supply through the same 33-pin module.
