BL-62B WiFi+Module

Bl-62b is a wireless module based on WiFi + ble single-chip SOC. It can meet the requirements of low-power and high-performance IOT application development. The core processor bl602 of the module integrates the baseband and and MAC design of 2.4G Wi Fi (802.11b / g / N) and ble 5.0. Its microcontroller subsystem consists of a low-power 32-bit RISC CPU, cache and memory. It has advanced power management unit and supports a variety of low power consumption modes. Peripheral interfaces include UART, GPIO, ADC, DAC, PWM, I2C, SDIO, etc.
