KEHIPI

KEHIPI ESP32-CAM 4M PSRAM OV2640 2MP Camera Development Board

SKU CH-D6HB-S052N

ESP32-CAM board with OV2640 2 MP camera, 4 MB PSRAM, Wi-Fi 802.11 b/g/n/e/i and Bluetooth 4.3 for IoT projects

  • Dual-core 32-bit CPU up to 240 MHz for responsive edge processing
  • 4M PSRAM plus 520 KB SRAM handles image buffers smoothly
  • OV2640 2MP camera streams JPEG over Wi-Fi 802.11 b/g/n/e/i
  • Bluetooth 4.3 BR/EDR and BLE adds low-power connectivity
  • MicroSD slot up to 4 GB stores captures locally

IoT Camera Board for Smart Devices

The KEHIPI ESP32-CAM pairs an OV2640 2MP camera with a dual-core 32-bit LX3 CPU running at 80MHz to 240MHz. It integrates WiFi 802.11b/g/n/e/i and Bluetooth 4.3 BR/EDR and BLE, making it suitable for wireless monitoring, QR identification and smart agriculture projects. The board includes 520KB internal SRAM plus 4M PSRAM and supports JPEG, BMP and grayscale output.

Build Integration and Connectivity

The module operates on a 5V 2A supply and exposes 9 IO ports alongside UART, SPI, I2C, PWM, ADC and DAC interfaces. An onboard PCB antenna with 2dBi gain handles the 2412-2484MHz spectrum, while a TF card slot accepts up to 4G storage for local image buffering. It runs embedded LwIP and FreeRTOS with support for STA, AP and STA+AP modes plus Smart Config/AirKiss provisioning.

Upgrade Path and Limitations

Developers moving from basic microcontrollers without wireless or camera support gain integrated image capture and WiFi upload in a single package. The jump is worthwhile when a project needs onboard Bluetooth 4.2 compliance and 32Mbit SPI flash for firmware. It does not serve builders who require higher resolution sensors, larger onboard storage or cellular connectivity options.

Questions sur cet article

What sustained-use limit appears first on this ESP32-CAM board?

The onboard PCB antenna is rated at 2 dBi gain, which can constrain wireless range during continuous streaming.

How much heat or noise does the module produce when running all day?

No fan or active cooling is present; the dual-core CPU operates at 80 MHz to 240 MHz and may become warm under constant WiFi and camera load.

What extra hardware must I already own to make this board work?

A USB-to-UART adapter and a 5 V, 2 A power source are required because the board has no built-in USB controller.
