Beken BK7256 320 MHz dual

Until now, I had only heard about Beken Bluetooth audio chips, but I’ve just been informed the company is also making WiFi chips such as the BK7256 that are notably found in some Tuya Smart Home modules.

Beken offers both RISC-V and Arm WiFi and Bluetooth chips with features summarized as follows:

Let's look into the KB7256 specifically, and see what software support and development kits are available for the Beken WiFi chips.

Beken BK7256 specifications:

Beken provides development boards for each of their BK72XX microcontrollers and fairly detailed documentation in Chinese and English (some sections are not translated yet) where you’ll find the datasheets for the chip, instructions to get started, an API reference, and sample code for video, audio, Bluetooth, a doorbell, and command line usage. All new Beken chips (BK7235, BK7236, BK7237, BK7256) are supported by the Armino development framework hosted on GitHub. The framework currently works for FreeRTOS and LiteOS, and the company is also working on getting it ported to RT-Thread and AliOS.

Applications for the BK7256 include smart speakers, low power cameras, motor control, and Smart Home appliances. The chip is also found in one upcoming "Wi-Fi and Bluetooth Low Energy Combo Core Board" from Tuya. I could not find any BK7256 boards or modules on Aliexpress, and the official board might need to be sourced directly from Beken at this time.
