Rock3/getting started
This guide is designed for ROCK 3 enthusiast. The purpose is to learn about the ROCK 3 board as well as how to prepare and set up for basic use. The ROCK 3 has two models, one called ROCK 3 Model A and the other one called ROCK 3 Model B. When you get a board, you need to know what Pi model it is and which hardware version it is. The information is printed in the top side of the board. We will introduce the board information as much as possible.
What you need
Necessary
- ROCK 3 main board
- ROCK 3 Model A or Model B
- One of the Storage media below:
- microSD, larger than 8GB.
- Power supply
- The ROCK 3 is powered by Type-C port and has a wide range of input voltage, from 9V to 21V. ROCK 3 supports USB Type-C PD 2.0 with 9V/2A, 12V/2A, 15V/2A and 20V/2A. Besides, the Pi supports QC 3.0/2.0 with 9V/2A and 12V/1.5A.
- The Type-C cable you using needs to support data communication. We call it USB Type-C charging data cable.
- USB Keyboard and Mouse
- With four USB-A connectors, ROCK 3 can be equipped with a full sized keyboard and mouse.
- Monitor and HDMI Cable
- ROCK 3 is equipped with a full sized HDMI connector. HDMI capable monitor is recommended.
- HDMI EDID display data is used to determine the best display resolution. On monitors and TVs that support 1080p (or 4K) this resolution will be selected. If 1080p is not supported the next available resolution reported by EDID will be used. This selected mode will work with MOST but not all monitors/TVs.
- USB to TTL serial cable
- ROCK 3 exports a dedicated serial console for CPU, which can access the low level debug message.
- USB Male A to Male A cable
- If you want write image on ROCK 3 from USB OTG port or use fastboot/adb commands you need an USB Male A to Male A cable to connect ROCK 3 and PC.
Optional
- microSD Card Reader
- For flashing the image into microSD Card
- USB type A to type A cable
- This is needed for fastboot/adb commands.
- USB to TTL serial cable
- This is needed for serial console.
- Ethernet cable
- ROCK 3 supports Internet access via WIFI or Ethernet.
- An Ethernet cable is used to connect your ROCK 3 to a local network and the Internet.
- Camera Module
- ROCK 3 supports camera function.
- LCD Module
- ROCK 3 supports LCD display function.
- Audio cable
- Audio can be played through speaker or headphones using a standard 3.5mm jack.
- Wireless Module
