Introduction

CB2L 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 connection.

CB2L features a built-in 32-bit MCU running at up to 120 MHz, with 2 Mbyte of flash memory and 256 KB RAM. This enables the module to support IoT cloud connectivity, and the MCU's signal processing extension instructions allow it to efficiently implement audio encoding and decoding. With 5 channels of 32-bit PWM output, the chip is well-suited for high-quality LED control.
