Description
ESP32-CAM is a WIFI+ Bluetooth dual-mode development board that uses PCB on-board antennas and cores based on ESP32 chips. It can work independently as a minimum system. It integrates Wi-Fi, traditional Bluetooth and BLE beacons with 2 high-performance 32-bit LX6 CPUs, 7-stage pipeline architecture, main frequency adjustment range of 80 MHz to 240MHz, on-chip sensor, Hall sensor, temperature sensor, etc.
Fully compliant with WiFi 802.11b/g/n/e/i and Bluetooth 4.2 standards, it can be used as a master mode to build an independent network controller, or as a slave to other host MCUs to add networking capabilities to existing devices.
ESP32-CAM can be widely used in various IoT applications. It is suitable for home smart devices, industrial wireless control, wireless monitoring, QR wireless identification, wireless positioning system signals, and other IoT applications. It is an ideal solution for IoT applications.
