Issues with the fan being noisy or not working are caused by loose mounting of the fan to the fan port.

Firmly pressing down on the fan at all 4 corners should see the issue improve. Also, there is double-sided tape on the back of the fan. If you tear off its protective backing, and stick the fan back into the fan port, that should provide a more permanent fix for the vibration noise caused by the loose mounted fan.

Pixel Doubling can make fonts more readable (larger) on a small screen with high resolution, however, there are drawbacks

Pixel Doubling affects the entire system. Enabling pixel doubling simply draws every pixel in the desktop as a 2×2 block of pixels on the screen, making everything exactly twice the size and resulting in a more usable desktop. But this will sacrifice screen quality.Will need more fiddling with other appearance settings to suit your own liking.To enable Pixel Doubling:Click on Menu (Raspberry icon).Select Preferences and choose Raspberry Pi Configuration.The Raspberry Pi Configuration window appears.On the Display tab, click on Pixel Doubling: ( ) Enable.Click OK and reboot the system.

Note: After reboot, everything on the screen becomes very big. You will need to customize the appearance settings as shown below. You may want to experiment with different appearance settings to suit your own liking.

To customize Appearance Settings:Click on Menu (Raspberry icon).Select Preferences and choose Appearance Settings.The Appearance Settings window appears.On the Menu Bar tab, set Size: Medium (24x24).On the System tab, set Font: to PibotoLt 8 and Mouse Cursor: Small.Finally, click OK and that's it.

Note: You may want to experiment with different appearance settings to suit your own liking.

You need to reinstall the LCD library using the following commands:

sudo pip install Adafruit_BBIO

sudo pip3 install Adafruit_BBIO

The SDA0 (BCM_GPIO-0) pin is reserved for Raspberry Pi startup detection, in order to control the power on/off of the PCBA board. So without this pin signal from the Raspberry Pi, the CrowPi2 will shutdown unexpectedly.

Crowpi2 software is recommended to run on a Raspberry Pi 4 Model B with 2GB RAM or higher (preferably with 4GB or 8GB).

Pressing Fn+F1 toggle the trackpad on/off.

We designed the (+) and (-) buttons to be used to adjust the screen brightness only. Too many ways to adjust the volume may be confusing to users, so adjusting the volume through the system or applications is considered a better way.

The latest CrowPi2 User Manual has been updated accordingly.

Depending on which one is not responding, try re-pair it with the wireless dongle as follow:

Pairing the Keyboard
1. Unplug the wireless dongle.
2. Switch off the keyboard and the mouse.
3. Plug the wireless dongle back into the CrowPi2, switch on the keyboard and you should see the Status light come on. When this happens, immediately press and hold down both the Esc and the Q keys until the Status light (blue light) starts blinking.
4. Keep the keyboard close to the wireless dongle.
5. Once the Status light stops blinking and on, it means you have successfully paired the keyboard.
6. If the Status light is still blinking, just unplug the wireless dongle and then plug it back into the USB port to see the result of step 5.

Pairing the Mouse
1. Unplug the wireless dongle.
2. Switch off the keyboard and the mouse.
3. Switch on the mouse and quickly plug the wireless dongle back into the CrowPi2.
4. Move the mouse around on a flat surface until the mouse pointer on the display moves.
5. When this happens, it means you have succeeded in pairing the mouse.

Step 1: Pair the mouse

1. First, power off both the keyboard, the mouse and uplug the wireless receiver.

2. Then, power on the mouse only, and plugin the receiver to CrowPi2 quickly.

3. Slide the mouse around until you can control the cursor on CrowPi2.

4. Once you can control the cursor on CrowPi2 with the mouse, it means you have successfully paired the mouse.

Step 2: Pair the keyboard

1. Unplug the wireless receiver.

2. Power off both the keyboard and the mouse.

3. Plugin the receiver to CrowPi2, power on the keyboard and you will see the red light comes on. While the red light still on, press the Esc + Q keys at the same time immediately; Then, you will see the red light starts blinking.

4. Move the keyboard close to the wireless receiver, once the blue light and red light turns on at the same time, it means you have successfully paired the keyboard.

5. You have successfully paired the keyboard and the mouse.

Now, you can power on the keyboard and mouse, and use them normally.

The official CrowPi2 system image is available Here.

Note: It's normal for your system to restart once, when booted for the first time, in order to expand the filesystem automatically.

You need to take out the SD card and use a computer for image burning, and it can be roughly divided into 3 steps:

1. Download the mirror
crowpi2_release_v1.2.0_en_20210305.zip

2. Format the memory card
Using SDFormatter software to format the SD card.
You can download this software from the download link at the bottom of this comment.

3. Install the image
Using Win32DiskImager software to install the image, which is very easy to operate.
You can download it from the download link at the bottom of this comment, too.


After you have burned the image, inserting the memory card into the Raspberry Pi of CrowPi2, and then turn it on.
