The BK3231 chip is a highly integrated single-chip Bluetooth HID device. It integrates the high-performance transceiver, rich features baseband processor, and Bluetooth HID profile.

A Bluetooth HID (Human Interface Device) device is a type of Bluetooth device that allows users to interact with a computer or other host device using standard human interface peripherals, such as keyboards, mice, game controllers, and other input devices. The HID profile is a Bluetooth profile that enables the seamless communication between such devices and the host.


1. Operation voltage from 2.8 V to 3.6 V

2. Bluetooth 2.1 compliant

3. -88dBm sensitivity for 1 Mbps mode and 2 dBm transmit power

4. HID v1.0

5. 16 MHz crystal reference clock

6. 56-pin QFN 7mmx7mm package for keyboard

7. I2C, SPI and UART interface
