[1]. This Raspberry Pi system image can run on all boards of the Raspberry Pi series, such as Raspberry Pi 4B, Raspberry Pi 3B+, 3B, etc.
[2]. After the system starts, the default username is corvin, and the password is also corvin. The password for the root user of the system is also corvin, and the default password can be modified by yourself.
[3]. The system has the 22 port ssh-server, 5900 port vnc-server, and 21 port ftp service enabled by default, allowing easy ssh connection, vnc remote desktop, and ftp connection.
[4]. The system has integrated drivers for the voice board and IMU board, so you can directly plug the voice board and IMU board into the Raspberry Pi for normal use.
[5]. This system is the latest official Raspberry Pi raspbian buster ARM32 system, using source code compiled ROS packages, so you cannot use apt to install ROS-related packages.
[6]. The activated system SD card can only be used on the Raspberry Pi mainboard it was bound to during activation. If the SD card is inserted into another Raspberry Pi mainboard, the ROS functions will be deleted.
[7]. After the first burning of the system, when the Raspberry Pi starts for the first time, it may not recognize the full capacity of the SD card. You need to use the raspi-config tool to expand the operation before it can recognize the full capacity of the SD card.
[8]. In addition to the essential software packages for installing ROS, the system also installs relevant packages such as mav_ros, moveIt, SLAM, etc.
