Maix Cube

The Maix Cube is designed for hobbyist who wants to pursue their passion with the latest technology. This incredibly powerful gadget is packed with a dual-core 64bit RISC-V 400 MHz processor, 8MiB of on-chip memory, and up to 128GB of expansion storage – perfect for storing all your projects!

SIPEED MaixCube can develop a programming learning kit, MaixCube integrates a 30W camera, expandable TF card slot, user buttons, IPS 1.3 inch display, 200mAh lithium battery, speaker, microphone, SPMOD, GROVE expansion interface, etc. on the hardware.

MaixCube is equipped with MaixPy by default on the software. Users can easily use MicroPython syntax to quickly get started with AI IoT development, and develop face recognition, object recognition, and other AI applications. At the same time, it also reserves development and debugging interfaces, which can also be used as a powerful AI learning development board.

Get started

Because MaixCube comes with its own GUI demo interface and sample programs, you can play with the preset programs first when you get the board.
After that, we will start to use MaixCube to get started with AIoT with MaixPy.

Before development, we need to understand and prepare related tools to reduce the pitfalls we have to follow because of insufficient preparation.

Steps to get started:

  1. Download the required drivers and software
  2. Connect the development board to the computer and install the USB driver
  3. Update the latest firmware
  4. Download and open the latest MaixPy IDE
  5. Connect MaixPy IDE to the development board Run the MaixPy sample program

3.1. Software and hardware preparation

Hardware preparation:

  • Computer one
  • MaixCube Development Board
  • One reliable USB Type-C data cable: pay attention to a reliable data cable

Software preparation:

  • USB driver
  • Kflash_gui
  • MaixPy IDE

When we get the Maix Cube and connect to the computer, we can open the device manager to check whether the serial port driver has been installed. The methods to open the device manager are:

  • This computer (right click) -> Properties -> Device Manager
  • Start menu (right click) -> Device Manager
  • Control Panel -> (Search) Device Manager

Update the firmware to the latest version

After the user gets the development board, the onboard firmware may not be the latest version by default, so there will be more or fewer bugs during use.
We need to update the firmware version to the latest version at this time

View update method: Update Firmware

Run the first program

  • LCD real-time preview Camera (when connecting with MaixPy IDE, select Maixduino)
import sensor, image, time, lcd

sensor.reset()
sensor.set_pixformat(sensor.RGB565)
sensor.set_framesize(sensor.QVGA)
sensor.skip_frames(time = 2000)
sensor.set_hmirror(1)
sensor.set_vflip(1)

clock = time.clock()

lcd.init(type=2)
lcd.rotation(2)

while(True):
    clock.tick()
    img = sensor.snapshot()
    print(clock.fps())
    img.draw_string(60, lcd.height()-120, "fps:"+str(clock.fps()), lcd.GREEN, scale=2)
    lcd.display(img)
