Introduction

CB3L 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 BLE connectivity. CB3L integrates a 32-bit MCU running at up to 120 MHz, with built-in 2 Mbyte flash memory and 256 KB RAM. This enables the module to support platform cloud connectivity, and the MCU's signal processing extension instructions allow it to efficiently implement audio encoding and decoding. It features rich peripherals such as PWM, UART, and SPI. Up to six 32-bit PWM outputs make the chip well-suited for high-quality LED control.
