The ESP32-CAM-MB module can operate independently as the smallest system. A new WiFi + Bluetooth dual-mode development board based on ESP32 design, using built-in PCB antenna, with 2 high-performance 32-bit LX6CPUs, using 7-level pipeline architecture, main frequency adjustment range from 80MHz to 240Mhz. Ultra-low power consumption, deep sleep current is as low as 6mA. It is an ultra-small Wi-Fi + BT / BLE SoC module. ESP32-CAM-MB adopts a Micro USB interface, a convenient and reliable convenient connection method to be applied to various terminal IoT hardware.
ESP8266 offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor. When ESP8266 hosts the application, and when it is the only application processor in the device, it is able to boot up directly from an external flash. It has integrated cache to improve the performance of the system in such applications, and to minimize the memory requirements. Alternately, serving as a Wi-Fi adapter, wireless internet access can be added to any microcontroller-based design with simple connectivity through UART interface or the CPU AHB bridge interface.
