Introduction: BL602 is a Wi-Fi+BLE chipset introduced by Bouffalo Lab, which is used for low power consumption and high performance application development. The wireless subsystem includes 2.4G radio, Wi-Fi 802.11b/g/n and BLE 5.0 baseband /osMAC design. The microcontroller subsystem includes a 32-bit RISC CPU with low power consumption, cache and memory. The power management unit controls the low power consumption mode. In addition, it also supports various security features. The external interfaces include SDIO, SPI, UART, I2C, IR remote, PWM, ADC, DAC, PIR and GPIO. Features: Low power consumption. High performance. 2.4G large memory. Support various safety functions. Multiple external interfaces. Note: Burning may be automatically upgraded, and the Partition file may be different. If the program runs abnormally, this Partition file can be replaced partition_cfg_2M.toml. After burning, the progress bar appears red. Please try again, or use the serial port tool to connect and enter the download mode correctly. The serial port will always print garbage. Package includes: 3 x WiFi Development Board
