1 Product overview
CB2L is built in with a 32-bit MCU whose running speed can be up to 120 MHz, a 2-MB
flash memory, and a 256-KB RAM, so as to support the Tuya cloud connection. The
MCU instructions specially extended for signal processing can effectively implement
audio encoding and decoding. There are 5 channels of 32-bit PWM output, making
the chip very suitable for high-quality LED control.
