📄️ System Introduction
In the previous chapter, we completed booting up the WalnutPi and logging into the system. The main difference between the desktop and non-desktop versions of WalnutPi: simply put, the non-desktop version is the desktop version with the desktop environment removed. Therefore, standard Linux commands and configuration instructions are generally applicable to both systems.
📄️ Pre-installed Software
The WalnutPi system comes pre-installed with some applications for user convenience. This section briefly introduces the relevant software. Applications are located in the Start Menu.

📄️ Shutdown and Restart
The WalnutPi runs an operating system. Unlike regular microcontroller boards that can simply be powered off, to protect the board, it is recommended to use the Log Out function in the menu bar and choose Shut Down or Restart from the dialog box. This avoids the risk of sudden power loss damaging the operating system or causing file loss.
📄️ CPU Temperature Information
The WalnutPi 1B's H616/H618 SoC features 4 built-in temperature sensors:
📄️ SoC Chip ID
The WalnutPi 1B uses the Allwinner H616/H618 SoC. Each chip has a unique chipid. Users can obtain the chipid using the following command to distinguish different boards.
📄️ Audio
Headphone Jack
📄️ IR Receiver
The WalnutPi has one onboard IR receiver.
📄️ USB Drive Mounting
Insert the USB drive into one of the WalnutPi's USB ports.
