This tutorial explains how to install the Jessie image on the Raspberry Pi 3 B board, enabling ROS development on the Raspberry Pi. First, let’s get acquainted with the Raspberry Pi development board. The Raspberry Pi (Chinese name: “树莓派”, abbreviated as RPi or RasPi/RPi) is a credit card-sized computer designed for computer programming education for students, and its system is based on Linux. The Raspberry Pi was developed by the Raspberry Pi Foundation, a charity registered in the UK, with Eben Upton as the project leader. In March 2012, Eben Epton from the University of Cambridge officially released the world’s smallest desktop computer, also known as a credit card-sized computer, which is only the size of a credit card but has all the basic functions of a computer.
The biggest change in the Raspberry Pi 3 B board is reflected in the processor—upgraded to a 1.2GHz quad-core ARM Cortex-A53, which has over ten times the performance of the first-generation Raspberry Pi.
Raspberry Pi founder Eben Upton stated: “Broadcom has brought a new BCM2837 SoC to the Raspberry Pi 3, which retains the same architecture as the MCB2835 and BCM2836, so projects that rely heavily on specific hardware details can continue to work.”
In addition to the 64-bit quad-core 1.2GHz processor, the Raspberry Pi 3 also features 1GB LPDDR2 memory, which is fully compatible with the applications that have been released. This is obviously very important for developers and users concerned about project platform migration.
In terms of networking, the Raspberry Pi 3 also directly features exciting 802.11n Wi-Fi and Bluetooth 4.1 support. For power supply, the third-generation Raspberry Pi requires a 2.5A USB charger, but using a regular 500mA USB output should also be fine (if no other power-hungry modules are connected).
Next, we will explain how to install the latest Raspberry Pi Jessie image on the Raspberry Pi 3; the specific operation process is shown below:
