BK7258MHT AIoT Smart Module | Wi-Fi 6 (2.4 GHz) + BLE + H.264 Encoding + JPEG Decoding + LCD Touch Display + Voice Interaction Integrated Solution, Ideal for Smart Voice Terminals

Product Description

     The BK7258MHT is a high-performance AIoT core module based on the Beken BK7258 chipset, featuring a 32-bit ARM Cortex-M33F core up to 480 MHz with FPU and DSP support for strong processing capability. It integrates multimedia functions including H.264 encoding, JPEG codec, and DMA2D acceleration for efficient image processing and smooth UI rendering, along with a built-in LCD controller supporting RGB, QSPI, and 8080 interfaces. With onboard 2.4 GHz Wi-Fi 6 and Bluetooth LE 5.4, it delivers stable high-speed connectivity and low-power communication, while also supporting voice interaction and audio processing such as AEC and microphone input for local voice control. Highly integrated and power-efficient with rich peripheral expansion, it is ideal for smart voice terminals, industrial HMIs, home appliance control panels, smart door devices, clocks, weather displays, and other AIoT applications with display and voice functionality.
