Market demand for small-package Bluetooth

In the rapidly expanding Internet of Things (IoT), size and power efficiency are not just advantages, they are often the defining requirements. From disposable medical sensors to compact consumer wearables, engineers are constantly challenged to pack more functionality into increasingly smaller form factors.

 

Mini Bluetooth Module

The key to meeting above challenge lies in selecting the right core Bluetooth connectivity component. In this regard，We have developed and launched the BT691, it emerges as a standout mini Bluetooth module, specifically engineered to deliver robust Bluetooth Low Energy (Gıcırdatmak) 5.1 performance in an incredibly compact and power-efficient package, enabling a new wave of innovative products.

 

Key Features

Bluetooth 5.1 Uyumluluk: Ensures improved location finding and longer-range communication compared to earlier BLE versions.

Ultra-Compact Dimensions: Measuring just 10mm x 11.9mm x 2mm, this module offers small footprints and saves crucial PCB space for other components.

Exceptional Power Efficiency: With a deep sleep current of only 1.6 µA and optimized active currents (TX: 3.5 anne, Rx: 2.2 anne), it is ideal for battery-powered and energy-harvesting devices that require years of operation.

Adequate Processing Power: The 32-bit ARM Cortex-M0+ CPU, coupled with 48 kB of RAM, handles application tasks and the BLE protocol stack efficiently.

Robust RF Performance: With a programmable transmit power from -19.5 DBM +2.5 dBm and a receiver sensitivity of -94 DBM, it provides a reliable wireless link.

 

Hardware Interfaces

Despite its small size, the FSC-BT691 offers a rich set of peripherals, making it a versatile core for various designs. The module’s pinout is designed for easy integration.

  • UART Interface:The primary channel for sending data and commands, supporting baud rates from 1200 ile 921600 BPS.
  • I2C Interface:Allows connection to a wide array of sensors (Örn., sıcaklık, ivmeölçer).
  • 10-bit adc:Three channels are available for battery voltage monitoring or reading analog sensors.
  • Programmable GPIOs:Provide control for LEDs, düğmeler, and other digital peripherals.

Pre-Certified for Faster Time-to-Market

A significant hurdle in wireless product development is navigating international certification processes. The FSC-BT691 module comes with pre-certifications for major markets, içermek:

  • FCC (Amerika Birleşik Devletleri)
  • İc (Kanada)
  • CE (European Union)
  • SRRC (Çin)
  • Telekk(Japonya)
  • KC(Kore)

 

This dramatically reduces the cost, complexity, and time required to bring a certified product to market, de-risking your development cycle.

 

Ideal Application Scenarios

The FSC-BT691 is perfectly suited for a wide range of compact IoT devices, örneğin:

  • Medical Disposables and Sensors:Where size, sterility, and battery life are critical.
  • Beacons and Proximity Tags:For asset tracking and indoor navigation.
  • Portable smart device:Demanding a small size and long battery life.
  • Industrial Sensor Nodes:For monitoring conditions in tight spaces.
