Customer Questions & Answers

What power supply requirements does it have, and what tolerance does the board’s 5V pin allow?

The ESP32-CAM board requires a stable 5V DC supply, with a minimum current of 500 mA recommended to avoid resets when the camera is active. The tolerance range for the 5V pin is usually between 4.75V and 5.25V. Supplies outside this range may cause faults or permanent damage.

What communication protocols does the board support, and what are the transmission speed limitations?

The module supports UART (typical speeds up to 115200 baud), SPI (up to 40 MHz, depending on the wiring), I2C (up to 400 kHz as master) and Wi-Fi 802.11 b/g/n (theoretical maximum speed of 72.2 Mbps, limited by the environment and firmware). BLE Bluetooth supports connections up to 2 Mbps under optimal conditions. Image transfer over Wi-Fi depends on file size and link quality.

What are the main thermal limitations and recommendations for continuous operation of the ESP32-CAM?

The ESP32-CAM is designed to operate between -20°C and 85°C. It does not have an integrated heatsink, so during prolonged use, especially when recording video or with Wi-Fi constantly active, it may heat up above 65°C in hot environments. Adequate ventilation is recommended. If used in enclosed cases, it is advisable to monitor the microcontroller temperature.

What are the dimensions, weight and components included exactly in the box of the ESP32-CAM?

The ESP32-CAM module measures approximately 40 mm x 27 mm x 4.5 mm, and weighs about 7 g. The box contents include the assembled ESP32-CAM module with its OV2640 camera pre-installed. No cables, microSD card or USB-Serial programming adapter are included.

What is the ESP32-CAM NodeMCU 5V WiFi with OV2640 camera used for?

This board is mainly used for Internet of Things (IoT) projects, such as smart devices, wireless control, remote monitoring and wireless identification systems.

What type of camera does this module include?

It includes an OV2640 camera module with built-in flash, and is also compatible with OV7670 cameras.

What interfaces does the ESP32-CAM board support?

It supports UART, SPI, I2C, PWM, ADC and DAC interfaces to make connection with other devices easier.

Is it possible to update the firmware remotely?

Yes, the board supports remote firmware update (FOTA), as well as local serial update.

What network modes does this board support?

It supports STA, AP and STA+AP network modes, allowing flexibility in WiFi connection.
