概要

Equivalent

The CH9141K is a Bluetooth serial port module chip. Equivalent products include:
- HC-05/HC-06 (common Bluetooth modules)
- RN4870/RN4871 (Microchip)
- BL654/BM78 (Laird)
- CC2541 (TI)
- JDY-31 (similar low-cost module)
These alternatives offer UART-based Bluetooth communication, though pin compatibility and features may vary. Check datasheets for exact replacements.

Application

The CH9141K is a Bluetooth dual-mode (BLE/BR/EDR) SoC chip primarily used in:
1. Wireless Peripherals: Keyboards, mice, game controllers.
2. Smart Home Devices: Remote controls, sensors, lighting.
3. Wearables: Fitness trackers, smartwatches.
4. IoT Applications: Data transmission, low-power sensors.
5. Audio Devices: Wireless headsets, speakers (supports SPP profile).
It features low power consumption, compact size, and supports Bluetooth 5.0, making it suitable for battery-operated and compact electronics.

Package

The CH9141K is typically available in a QFN-32 package (Quad Flat No-lead, 32 pins). This compact, surface-mount package is suitable for space-constrained applications, offering good thermal and electrical performance. Exact dimensions and pin configurations can be found in the datasheet. For precise details, refer to the manufacturer's documentation.
