ACK Solution

Beken platform offers comprehensive resources, documentation, and technical support to facilitate a smooth transition to ACK-enabled devices.

Internet of Things

We develop and design cost-effective Wi-Fi SOC for IoT applications with high integration, stable performance and low power consumption.

Internet of Vehicles

The product complies with the national standard GB20851 and the automobile safety standard GB3844, applied to the national standard ETC.

Smart Speaker

A powerful, large-capacity, highly integrated Wi-Fi audio and video AIoT chip, specially designed for smart speaker/network camera applications, the highest frequency can reach 180MHz, support real-time operating system (Thread embedded OS) and Wi-Fi protocol stack, with ADC, audio codec, image encoder. It is very suitable for smart devices in the IoT and light artificial intelligence product categories.

Smart Story Teller

A powerful, large-capacity, highly integrated Wi-Fi audio and video AIoT chip, specially designed for smart children's robot / story teller applications, the highest frequency can reach 180MHz, support real-time operating system (Thread embedded OS) and Wi-Fi protocol stack, with ADC, audio codec, image encoder. It is very suitable for smart devices in the IoT and light artificial intelligence product categories.

Bluetooth Speaker

Bluetooth speaker refers to an audio device with a built-in Bluetooth chip that replaces the traditional wire connection with a Bluetooth connection, mainly connected to Bluetooth devices such as mobile phones, tablets or notebooks.

Bluetooth Earphone

The delivery of real-time audio through a wireless connection is now routine and convenient. Bluetooth technology enables reliable point-to-point audio streaming from a PC or mobile device to a range of light-weight wireless devices— such as ear buds, headsets, speakers, hearables, media stream adapters, and more.

Wireless Keyboard & Mouse

The wireless keyboard and mouse can be used at a long distance from the computer. According to the connection protocol, it can be divided into: 2.4G private protocol wireless keyboard and mouse; Bluetooth protocol wireless keyboard and mouse; Bluetooth+2.4G protocol wireless mouse.

Drone

Our 2.4G private protocol drone flight control solution can realize wireless remote control, easy to develop, single SOC solution, with high cost performance, low power consumption, and strong functions; 802.11 b/g/n drone WIFI image transmission solution is the first SOC solution in the industry.

Digital Microphone

Wireless microphone products use digital modulation for transmission, which can completely shield the noise caused by external interference and achieve high-quality low-latency voice transmission. The product is fully integrated with transceiver, baseband signal encoding and decoding, 24-bit 48 kHz microphone input and audio output, automatic antenna selection, automatic gain control and frequency tracking.

Walkie-Talkie

The walkie-talkie products include BK4802 specially designed for toys and BK4815 designed for civilian use. In addition to integrated transceivers and voice input and output units, the product also contains signaling functions such as CTCSS, CDCSS, SELCALL, DTMF, and FSK. Suitable for various applications from personal communication, toys, wireless meter reading, etc.
