=========
Overview
=========
BL602/BL604
is Wi-Fi + BLE combo chipset for ultra-low-cost and low-power application.
Wireless subsystem contains 2.4G radio, Wi-Fi 802.11b/g/n and BLE 5.0 baseband/MAC designs.
Microcontroller subsystem contains a low-power 32-bit RISC CPU, high-speed cache and memories. Power Management Unit controls low-power modes. Moreover, variety of security features are supported.
Peripheral interfaces include SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR, and GPIOs.
