ESP32 CAM development board
The MCDODO Freenove ESP32 CAM kit provides a dual-core 32-bit microcontroller running at 240 MHz with 4 MB flash and 8 MB PSRAM. It includes an onboard camera, 2.4 GHz Wi-Fi, and Bluetooth 4.2 for wireless IoT projects. A 1 GB memory card and card reader are supplied for local storage. Tutorials and example projects in MicroPython and C guide beginners through setup and programming.
Sustained operation with camera and wireless
The dual-core 32-bit processor handles continuous image capture and wireless transmission without relying on burst performance. The 8 MB PSRAM supports frame buffering during extended streaming or time-lapse sequences. Onboard Wi-Fi and Bluetooth 4.2 maintain connectivity for long-running sensor nodes or remote monitoring tasks. The board draws power directly from the USB connection during development and deployment.
Practical limits of the 2.4 GHz interface
The 2.4 GHz Wi-Fi band offers wide compatibility but shares spectrum with many household devices, which can affect throughput in dense environments. Bluetooth 4.2 LE is suited for low-bandwidth sensor links rather than high-speed data transfer. The single antenna serves both radios, so simultaneous heavy Wi-Fi and Bluetooth traffic may reduce reliability. Range depends on antenna orientation and surrounding obstacles.

商品問答
How much power does the 240 MHz ESP32 draw when running continuously?
The board runs from a standard USB 5 V supply; typical active current is well within a laptop port or phone charger budget, and deep-sleep modes drop consumption to micro-amp levels for battery projects.
What must I already have to start programming the board?
A computer with the Arduino IDE or MicroPython toolchain installed, a USB-A to Micro-USB cable, and the supplied 1 GB micro-SD card with reader for storage-heavy sketches.
Will the Bluetooth 4.2 radio interfere with my older 2.4 GHz gear?
Both Wi-Fi and Bluetooth share the 2.4 GHz band, but the ESP32’s coexistence mechanism time-slices the antennas so legacy keyboards, mice or sensors stay connected while the board streams camera data.
