ESP32-CAM-MB Introduction
The HK-ESP32-CAM-MB module is a compact camera module measuring 39.8 x 27 mm. This module functions independently and is built on an advanced WiFi+Bluetooth dual-mode development board based on ESP32. It features a PCB on-board antenna, two high-performance 32-bit LX6 CPUs, a 7-level pipeline architecture, and a main frequency range of 80MHz to 240MHz. It boasts ultra-low power consumption with a deep sleep current as low as 6mA, making it an ultra-small 802.11b/g/n Wi-Fi + BT/BLE SoC module.
- Micro USB interface for convenient and reliable connections suitable for various IoT hardware applications.
