⭐ Specification
OV2640 ESP32-CAM:
– Module: ESP32-CAM
– Microcontroller: ESP32-S Dual Core
– Camera Sensor: OV2640
– Image Resolution: 2 Megapixel (UXGA 1622×1200)
– Operating Voltage: 5V (via Micro USB port or 5V pin); 3.3V (via 3.3V pin)
– Connectivity: WiFi 802.11 b/g/n, Bluetooth 4.2 BR/EDR & BLE standards
– Storage: MicroSD card slot (supports FAT format; capacity varies, e.g., up to 4GB typically supported, higher capacities like 32GB or 64GB may work but depend on specific card and firmware)
– Programming Interface: Micro USB port (usually features an onboard CH340G or similar USB-to-Serial converter for direct programming from a PC)
– GPIO Pins: Multiple available for user peripherals (e.g., I2C, SPI, UART access)
– Dimensions (Board Only): Approx. 40.5mm x 27mm x 4.5mm (camera module and lens add to overall height)
– Antenna: Onboard PCB antenna. Some variants may include an IPEX connector for an external antenna (confirm with specific board if external antenna is crucial).
– Flash LED: Onboard high-brightness LED, can be used as a flash.
– Low Power: Supports deep sleep mode for low power consumption (as low as 6mA).

RHYX-M21-45 ESP32 CAM:
– Model Identifier: RHYX-M21-45.
– The main difference between ESP32 CAM modules with OV2640 and RHYX M21-45 cameras lies in their pixel format support. OV2640 supports both JPEG and RGB565, while RHYX M21-45 primarily uses RGB565 and may not directly support JPEG. This means that when using an ESP32 CAM with an RHYX M21-45 camera, you’ll likely need to process the image data in RGB565 format and may need to handle compression or conversion if you need JPEG output.

Quick Guide for Selecting Variation:
– Choose ‘OV2640 ESP32-CAM’ for the widely recognized standard module.
– Choose ‘RHYX-M21-45 ESP32 CAM’ if this specific model number (RHYX-M21-45) is required for your project, documentation, or if it’s the variant currently in stock. Functionally, both offer the same robust camera and wireless capabilities for your IoT projects.
