ESP32 Wifi And Bluetooth Module With CP2102 Converter

The CP2102/9 is a highly-integrated USB-to-UART Bridge Controller providing a simple solution for updating RS232 designs to USB using a minimum of components and PCB space. The CP2102/9 includes a USB 2.0 full-speed function controller, USB transceiver, oscillator, EEPROM or EPROM, and asynchronous serial data bus (UART) with full modem control signals in a compact 5 x 5 mm QFN-28 package.With some minor exceptions, the address mapping of two CPUs is symmetric, meaning they use the same addresses to access the same memory. Multiple peripherals in the system can access embedded memory via DMA.
ESP32 uses CMOS for single-chip fully-integrated radio and baseband and also integrates advanced calibration circuitries that allow the solution to dynamically adjust itself to remove external circuit imperfections or adjust to changes in external conditions. It is a dual-core system with two Harvard Architecture Xtensa LX6 CPUs. All embedded memory, external memory, and peripherals are located on the data bus and/or the instruction bus of these CPUs.

ESP32 is a single chip 2.4 GHz Wi-Fi and Bluetooth combo chip designed with TSMC low-power 40 nm technology. It is designed and optimized for the best power performance, RF performance, robustness, versatility, features, and reliability, for a wide variety of applications, and different power profiles.
