Introduction

CB3S is a low-power embedded Wi-Fi module. It consists of a highly integrated wireless RF chip BK7231N and a small number of peripheral components, supporting both AP and STA dual-role connectivity as well as Bluetooth Low Energy connectivity. CB3S features a built-in 32-bit MCU running at up to 120 MHz, with 2 Mbyte of flash memory and 256 KB RAM. It supports IoT cloud connectivity, and the MCU's instruction set extensions for signal processing enable efficient audio encoding and decoding. CB3S offers rich peripherals such as PWM and UART. With up to six 32-bit PWM outputs, the module is well-suited for high-quality LED control.
