Green ESP32-CAM board with OV2640 camera module and Micro USB port

Alphacool

Alphacool ESP32 CAM Development Board 2 in 1 Accessories

SKU CH-NT2B-9SEB5

An ESP32-CAM board with OV2640 camera, MPU6050, BME280, analog microphone and Micro USB, supporting UART, SPI, I2C, PWM, ADC, DAC and 802.11 b/g/n Wi-Fi plus BT/BLE for IoT projects

  • ESP32-CAM enables diverse IoT projects with integrated OV2640 camera
  • Ultra-low power deep sleep at 6mA extends battery life
  • Multiple interfaces UART SPI I2C PWM ADC DAC for flexible connectivity
  • Onboard MPU6050 BME280 analog MIC add motion and environment sensing
  • Micro USB CH340C simplifies programming and power at 4.75V-5.25V

ESP32 CAM development kit for IoT projects

This kit provides four ESP32 CAM boards, each combining an ESP32 microcontroller with an OV2640 camera module and a Micro USB to serial adapter. The boards include reserved connections for an MPU6050 sensor, a BME280 sensor and an analogue microphone, and they support interfaces such as UART, SPI, I2C, PWM, ADC and DAC. Deep-sleep current is as low as 6 mA, and the module operates on a 4.75 V to 5.25 V supply via Micro USB.

Makers and developers building Wi-Fi or Bluetooth

The boards suit hobbyists and engineers creating smart-home devices, wireless monitoring, QR identification or positioning systems that need a compact, self-contained camera module with wireless connectivity. Projects requiring higher-resolution imaging, built-in environmental sensors or a different wireless protocol should consider other platforms.

OV2640 camera module with Micro USB programming

The OV2640 sensor provides the image capture capability, while the Micro USB port supplies power and a serial connection for flashing firmware. This combination determines whether the board can be integrated directly into a custom IoT enclosure without additional programmers or power circuitry.

Questions about this item

How do I choose among the four identical ESP32 CAM boards in the set?

All four boards carry the same OV2640 camera and ESP32 module, so any unit works for a given project; keep spares for parallel nodes or replacements.

What does the 6 mA deep-sleep current mean for a battery-powered device?

At 6 mA the board can sleep for weeks on a modest Li-ion cell, waking only when the PIR or timer triggers a capture.

Which interfaces does the Micro USB port actually provide?

The Micro USB connector carries the CH340C serial link for flashing and power, while the ESP32 itself exposes UART, SPI, I2C, PWM, ADC and DAC on the pin headers.
