Description
M5CameraX is a development board for image recognition. It features an ESP32(4M Flash + 520K RAM) chip and 2-Megapixel carmera(OV2640).M5Camera offers plenty of storage, with an extra 4 Mbyte PSRAM. It also supports image transmission via Wi-Fi and debuging through USB Type-C port.
The hardware comes preloaded software, programmed by ESP-IDF. It is an application to run Wi-Fi camera. The output image is size 600*800, since it’s 2-Maga camera, you sure can optimize the software to output the maximum size of photos.
what this software can do?
- Power the board via USB type-C or GROVE
- Use your phone to Wi-Fi scan an AP name start with ‘m5stack-‘ and click to connect this AP.
- Open up web browser on your phone and visit 192.168.4.1
- Then here comes the picture. Video is about 5-6 frames per senconds. not super fast.
The hardware also comes with some reserved weld pad, just in case you want put these chips back on board.
- 9-axis gyroscope (MPU6050)
- pressure sensor (BME280)
- Analog MIC (SPQ2410)
- Lipo Battery power pins
Please notice: There are 2 types of M5Camera
- Model A & Model B
- They have different circuits, can be identified by backside sticker
- Model A is halt production. The new coming M5Camera is just Model B
- In Model A circult design MPU6050 and camera sensor have I2C conflict, which means you can’t use both at the same time.
- Model B have better performance on image quality and processing speed.

Jargon buster
Plain-language definitions for the technical terms used above.
- BLE
- BLE stands for Bluetooth Low Energy, a Bluetooth mode designed for lower power use and modern phone compatibility. It matters because BLE support can make the module easier to use with Apple devices and battery-powered projects, though it may behave differently from classic serial Bluetooth.
- ESP-IDF
- ESP-IDF is Espressif’s official software development framework for ESP32-family chips. It gives more direct control over the hardware than beginner-style environments, which can help with advanced features like Wi-Fi, Bluetooth, audio and power management.
- ESP32
- ESP32 is a family of microcontroller modules with built-in wireless features such as Bluetooth and WiFi. Knowing this product uses an ESP32-based module helps explain how it provides wireless serial communication and firmware update features.
- Flash memory
- Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.
- Grove
- Grove is a plug-in connector ecosystem for sensors and modules that avoids soldering and jumper wires. Grove compatibility matters because it can make it quicker to add supported I2C devices, as long as the cable and voltage are suitable.
- Gyroscope
- A gyroscope measures rotation, such as how fast a board is turning around its X, Y, and Z axes. This matters for projects like gesture controls, balancing robots, and motion tracking where tilt or rotation changes need to be detected.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- PCB antenna
- A PCB antenna is an antenna pattern built directly into the circuit board rather than a separate metal antenna. It matters because placement, nearby metal and enclosure design can affect wireless range.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- USB Type-C
- A reversible USB connector used for power and data on many modern devices. On this kit it indicates an alternate 5V power input, which may be useful for setup or charging without the solar panel.
