TUYA CB3S(tjrl)

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 connections as well as Bluetooth Low Energy connectivity. CB3S features a built-in 32-bit MCU running at up to 120 MHz, with 2 Mbyte onboard flash and 256 KB RAM. It supports Tuya IoT cloud connectivity, and the MCU's signal processing extension instructions enable efficient audio encoding and decoding. CB3S offers a rich set of peripherals, including PWM and UART. Up to six 32-bit PWM outputs make it ideal for high-quality LED control.
