: ESPWROOM32 development boardWIFI+Bluetooth dualcore CPU low power: consumption ESP32 CP2102: Product Introduction ESPWROOM32 is a universal WiFi+BT+BLE MCU module with powerful functions and a wide range of uses. It can be used for lowpower sensor networks and demanding tasks such as voice encoding audio streaming and MP3 decoding etc. The core of this module is the ESP32DOWDQ6 chip which is scalable and adaptive. The two CPU cores can be individually controlled or powered on. The adjustment range of the clock frequency is from 80MHz to 240MHz. The user can cut off the power of the CPU and use the lowpower coprocessor to continuously monitor the status change of the peripherals or whether certain analog quantities exceed the interval value. ESP32 also integrates a wealth of peripherals including capacitive touch sensors Hall sensors lownoise sensor amplifiers SD card interface Ethernet interface highspeed SDIOSPI UART I2S and I2C. Features 1. The onboard CP2102 stable USB to TTL chip ensures the normal communication of the serial port. 2. Support automatic download no need to manually switch download and operation mode. 3. Immersion gold craft. 4. Support development on Windows system (cygwin and msys32 simulation environment) and Linux system 5. Support ESP32 CPU andMemory ESP32DOWDQ6 has two builtin lowpower Xtensa@32bitLX6MCUs. Onchip storage includes: 448KB of ROM used for program startup and kernel function calls. 520KB onchip SRAM for data and instruction storage. The 8KB of SRAM in the RTC that is the RTC slow memory can be accessed by the coprocessor in Deepsleep mode. The 8KB of SRAM in the RTC that is the RTC fast memory can be used for data storage and accessed by the main CPU when the RTC is started in Deepsleep mode. 1kbit eFuse of which 256bit is dedicated to the system (MAC address and chip settings); the remaining 768bit is reserved for user applications these applications include Flash encryption and chip ID. ESPWROOM32 integrates 4MB SPI Fl ash.
