ESP32 CAM MB WIFI Bluetooth Development Board
Series ESP32
ESP32 overview
The HK-ESP32-CAM-MB module is a small camera module with a size of 39.8*27*. This module can work independently as the smallest system. A new WiFi+Bluetooth dual-mode development board based on ESP32 design, using PCB on-board antenna, with 2 high-performance 32-bit LX6CPU, using 7-level pipeline architecture, main frequency adjustment range 80MHz to 240Mhz. Ultra-low power consumption, deep sleep current is as low as 6mA. It is an ultra-small 802.11b/g/n Wi-Fi + BT/BLE SoC module-ESP32-CAM-MB that adopts a Micro USB interface, a convenient and reliable connection method, convenient to apply to various IoT hardware terminal occasions.
