Getting Started with the Freenove ESP32-Wrover CAM Board

This is a quick getting started guide for the Freenove ESP32-Wrover CAM board. This board features an OV2640 camera, several GPIOs to connect peripherals, and a built-in programmer with a USB connector, which makes it easy to upload code to the board. We’ll take a quick look at the board and show you some examples of how to program it using the Arduino core for the ESP32.

Introducing the Freenove ESP32-Wrover CAM Board

The Freenove ESP32-Wrover CAM board is an ESP32 development board with the ESP32-Wrover-E chip (with 4 MB PSRAM) and an OV2640 camera.

It has a USB-to-UART converter so it’s straightforward to upload code to the board. You just need to
connect a USB cable to the board and connect it to your computer to upload code or apply power. There’s no need for extra circuitry or an FTDI programmer (contrary to the ESP32-CAM AI-Thinker board).

It comes with several exposed GPIOs if you want to connect other peripherals like sensors and outputs (many more GPIOs than the ESP32-CAM AI-Thinker). Additionally, if you’re not using the camera, you can use it as a regular ESP32 with a wide number of available GPIOs. The GPIOs with a slash above the numbers are the ones used by the camera.

There are RESET and BOOT buttons, which makes it easy to reset the board or put it in flashing mode if needed.

There are four onboard LEDs:

ON: when lit, it means the board is being powered on.
RX/TX: will blink when you’re using serial communication.
IO2: it’s a built-in LED connected to GPIO 2—useful for debugging purposes.

This board is very practical, the only downside is that it doesn’t come with a microSD card slot. However, it comes with available GPIOs that you can use to connect an external microSD card module if needed.

Freenove ESP32-Wrover CAM Board Features

Here’s a summary of the Freenove ESP32-Wrover CAM board features:

ESP32-Wrover-E Chip with 4MB PSRAM
Built-in USB-to-UART (CH340C drivers) — no need for an FTDI programmer
Camera OV2640 2 Megapixel
BOOT and RST buttons
LED indicators (RX/TX ON/OFF, and built-in LED (GPIO2))
Onboard antenna

Freenove ESP32-Wrover CAM Board Pinout

The following diagram shows the pinout for the ESP32-Wrover CAM board. You can click on the image to see it in full-size.

Freenove ESP32-Wrover Cam Pinout — Image source

There are labels indicating the features of each pin. You can clearly see which pins are being used by the camera, the power pins, PWM pins, ADC pins, etc.

Freenove ESP32-Wrover CAM Board – Camera Pin Definition

Here’s a table with the connections between the ESP32 and the camera:

OV2640 Camera	ESP32
XCLK	GPIO 21
SIOD	GPIO 26
SIOC	GPIO 27
Y9	GPIO 35
Y8	GPIO 34
Y7	GPIO 39
Y6	GPIO 36
Y5	GPIO 19
Y4	GPIO 18
Y3	GPIO 5
Y2	GPIO 4
VSYNC	GPIO 25
HREF	GPIO 23
PCLK	GPIO 22

Note that when you’re using the camera, you can’t connect peripherals to the GPIOs used by the camera. Otherwise, the camera won’t work properly. When you’re not using the camera, you can use this ESP32 board as a “regular” ESP32 and you can use the camera pins for other purposes.

The pin definition for the ESP32-Wrover CAM board (Freenove brand) in your Arduino sketches should be as follows (in some of the Arduino examples, this pin definition is under the CAMERA_MODEL_WROVER_KIT definition).

#define PWDN_GPIO_NUM -1
#define RESET_GPIO_NUM -1
#define XCLK_GPIO_NUM 21
#define SIOD_GPIO_NUM 26
#define SIOC_GPIO_NUM 27
#define Y9_GPIO_NUM 35
#define Y8_GPIO_NUM 34
#define Y7_GPIO_NUM 39
#define Y6_GPIO_NUM 36
#define Y5_GPIO_NUM 19
#define Y4_GPIO_NUM 18
#define Y3_GPIO_NUM 5
#define Y2_GPIO_NUM 4
#define VSYNC_GPIO_NUM 25
#define HREF_GPIO_NUM 23
#define PCLK_GPIO_NUM 22

Because this board uses the same camera used in the ESP32-CAM board, the examples for the ESP32-CAM (that don’t use microSD card) should also work with the Freenove ESP32 Camera board by changing the pin definition. The examples that use a microSD card, should also be compatible if using an external microSD card module and adjusting the pin definition on the code.

Freenove ESP32-Wrover CAM vs ESP32-CAM Ai-Thinker

Which one is better? The ESP32-CAM AI-Thinker of the Freenove ESP32-Wrover Cam? It will depend on your project requirements, let’s compare those boards.

Both the ESP32-CAM Ai-Thinker and the Freenove ESP32 Camera come with an ESP32 chip. The AI-Thinker boards usually come with the ESP32-S chip, and the Freenove brand comes with the ESP32-Wrover-E. Both chips are similar in terms of performance.

They both have the same camera model, an OV2640 camera. This means that most projects for the ESP32 Ai-Thinker will also work with the Freenove board and vice-versa by just changing the pin assignment in the code.

The ESP32-CAM Ai-Thinker comes with a built-in microSD card slot, while the Freenove doesn’t. The Freenove comes with more accessible GPIOs than the Ai-Thinker, including GPIOs being used by the camera. This means that when you’re not using the camera, you have more GPIOs to use, almost as in a regular ESP32 board. If you intend to use a microSD card in your projects, maybe the ESP32-CAM is a better idea. However, you can easily connect a microSD card module to the Freenove because it comes with several available GPIOs.

The Freenove comes with BOOT, and RESET buttons, while most ESP32-CAM Ai-Thinker boards only come with RESET button.

The Freenove comes with built-in indicator LEDs, and the Ai-Tinker doesn’t. This makes me think that the ESP32-CAM Ai-Thinker is better in terms of power consumption, even though I haven’t tested it.

The Freenove comes with a built-in USB to TTL converter, which means you can easily upload code to the board and provide power through the USB socket. The AI-Thinker board doesn’t come with this feature, which is a big drawback when you’re experimenting with code and debugging—uploading code can become a tedious task.

The Freenove comes with an onboard antenna, while the Ai-Tinker is available with an onboard antenna and with the possibility to connect an external antenna to increase the wi-fi range.

For a better comparison between the ESP32-CAM AI-Thinker and the Freenove ESP32-Wrover CAM, check the table below.

Programming the ESP32-Wrover CAM board with Arduino IDE

In this getting started guide, we’ll show you a quick example to demonstrate how to program your board using Arduino IDE. Before proceeding, you must have Arduino IDE installed on your computer, as well as the ESP32 add-on for the Arduino IDE.

We recommend following the next tutorial to install the Arduino IDE and add support for the ESP32 boards if you haven’t already:

Installing the ESP32 Board in Arduino IDE (Windows, Mac OS X, Linux)

Freenove ESP32-Wrover CAM Video Streaming Web Server Example

In this section, we’ll upload an example that creates a video streaming web server that you can access on your local network.

In the Arduino IDE, go to Tools > Board > ESP32 Arduino, and then select ESP32 Wrover Module.

Arduino IDE selecting ESP32 Wrover Module

Go to File > Examples > ESP32 > Camera and open the CameraWebServer example.

Make sure you select the right board on the code (remove the // on the CAMERA_MODEL_WROVER_KIT and make sure all the other board selections have //), as shown below:

CameraWebServer example selecting camera wrover kit

// ===================
// Select camera model
// ===================
#define CAMERA_MODEL_WROVER_KIT // Has PSRAM
//#define CAMERA_MODEL_ESP_EYE // Has PSRAM
//#define CAMERA_MODEL_ESP32S3_EYE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_PSRAM // Has PSRAM
//#define CAMERA_MODEL_M5STACK_V2_PSRAM // M5Camera version B Has PSRAM
//#define CAMERA_MODEL_M5STACK_WIDE // Has PSRAM
//#define CAMERA_MODEL_M5STACK_ESP32CAM // No PSRAM
//#define CAMERA_MODEL_M5STACK_UNITCAM // No PSRAM
//#define CAMERA_MODEL_AI_THINKER // Has PSRAM
//#define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM
// ** Espressif Internal Boards **
//#define CAMERA_MODEL_ESP32_CAM_BOARD
//#define CAMERA_MODEL_ESP32S2_CAM_BOARD
//#define CAMERA_MODEL_ESP32S3_CAM_LCD

Then, scroll down the code a bit and insert your network credentials on the ssid and password variables so that the board can connect to your network.

CameraWebServer example SSID and password

const char* ssid = "REPLACE_WITH_YOUR_SSID";
const char* password = "REPLACE_WITH_YOUR_PASSWORD";

After selecting the right board and inserting your network credentials, you can upload the code to the board.

Upload Code to the Freenove ESP32-Wrover CAM Board

Uploading code to the Freenove ESP32-Wrover CAM is straightforward, there’s no need for extra circuitry or an FTDI programmer. You just need to connect a USB cable (with data wires—USB cables that are charge-only won’t work to upload code) to the board USB connector and connect it to your computer.

Then, in the Arduino IDE, go to Tools > Port and select the COM port it is connected to.

Don’t see the COM port, or it is greyed out? It means you might not have the required drivers installed. This specific board uses the CH340 drivers. So, do a quick search to install those drivers on your operating system. After installing the drivers, try to upload the code again.

Then, you need to select a board model in the Tools menu.

Arduino IDE board selection for Freenove ESP32-Wrover CAM

Select the following settings:

Board: ESP32 Wrover Module
Partition Scheme: Huge APP (3MB No OTA) (or different, depending on your project requirements).

Finally, you just need to click the upload button.

After a few seconds, the code should be successfully uploaded to the board.

Demonstration

After uploading the code, open the Arduino IDE Serial Monitor at a baud rate of 115200.

Press the board RST button. The ESP32 IP address will be printed on the Serial Monitor.

CameraWebServer example Serial Monitor IP address

Open a browser on your local network, and type the ESP32 IP address. In my case:

http://192.168.1.142

You should get access to a page where you can start video streaming and get pictures from the camera.

Press the Start Streaming button to start video streaming or the Get Still button to take photos.

CameraWebServer example ESP32-CAM control buttons

There are also several menus that you can play with to adjust the camera settings.

ESP32 Camerawebserver example video streaming on browser

For higher resolutions, the picture is pretty good. However, video streaming in higher resolutions with this board is a bit slow if you’re not right next to the router.

Currently, this example doesn’t have face recognition enabled for this board, but face detection works for CIF or lower resolutions.

Great content, great resource as always. I minor note there is an error in your board comparison table, the board photos are reversed.
Unrelated but I would be interested if you do more on ESP32 using BLE, for example how to connect to a radar module like the Hi-Link LD2410B or C? Found only info on this for ESPHome/Python. Thanks

Is it possible to use the camera-gpios while the camera is connected but not >actively< in use?
E.g. if I were to use the camera for single pictures only and not video capture – could I use the gpios for sensors and stuff “between the frames”? I intend to only take a few photos per day.

I apologise if this is a stupid question to ask – I’m pretty new to esp32 / arduino and currently still exploring and planning a project.

Thanks in advance and best regards!

  As Sara says, theoreticaly you can. But be aware that the camera components are always connected to the Gpio’s and tey are not always tolerant to “external” signals/voltages, and they can influence your “extra” connected input/output signals (they are connected in parallel that way).

    Thanks very much JPe!
    I will try it out and keep you updated. Maybe the camera specifications give some insight about pins that might be more tolerable. (Like pins that not only send data to the esp but also receive signals under certain circumstances.)
    Or do you think one might use a cable extension module to get the actual pins exposed and then use diodes to protect the camera from incoming current?

Hi, I followed the instructions, all clear and well written.
The Esp32-Wrover is right next to the router. I tried powering the device from the laptop USB and from a 2amp power pack.
Unfortunately, the snap shots (QVGA(320×24) take about 2-5 seconds after the onboard led flash shows its received the request.
Streaming is pretty impossible.
Could it be that I need the antenna, or a manufacture fault?

  Hi.
  What board did you select in Tools > Board?
  Are you using the Freenove pins in that code you’re using?
  Regards,
  Sara
