1 Product Description
WB2S has a built-in 32-bit MCU running at the highest speed of 160 MHz, built-in 4Mbyte flash memory and
400KB RAM.
Support JLINK cloud connection, WB2S has rich peripherals, such as PWM, UART, I2S. Up to five 32-bit PWM
outputs make the chip ideal for high-quality LED control.
