Notes:

The recommended current for this board is 3 A. The reason is as the following:

The onboard components need about 1 A, the 4 USB ports can draw a total of 1 A combined,

one USB port alone can also draw 1 A and the remaining current is for expansion header and

others.

2.2 Pinout Diagram

The following is the pinout diagram:

StarFive

Quick Start Guide 2 Hardware Overview

www.starfivetech.com Page 8 V1.1 (2022-03-01)

Notes:

Each GPIO pin can safely draw a maximum current of 39 mA, whereas the maximum current

draw when all GPIOs are combined should be less than 100 mA. Please take this into account

or otherwise you will end up destroying the GPIO pins.

All GPIOs can be configured to support different functions including but not limited to SDIO,

Audio, SPI, I2C, UART and PWM.

For the instructions, refer to StarFive_40-Pin_GPIO_Header_User_Guide.

3 Getting Started

3.1 Required Hardware

You need to prepare the following hardware before getting started with VisionFive：

⚫VisionFive

⚫16GB (or more) micro-SD card

⚫micro-SD card reader

⚫Computer (PC/Mac/Linux)

⚫USB to serial converter (3.3 V I/O)

⚫Ethernet cable

⚫Power adapter (5 V / 3 A)

⚫USB Type-C Cable

3.2 Connecting a Fan

It's recommended to use a fan with VisionFive. You can connect a 2-pin 5 V fan to the board

as follows:

Figure 3-1 Connecting a Fan

3.3 Flashing Fedora OS to Micro-SD Card

Now we need to burn Fedora (which a Linux distribution) to a micro-SD card, so that it can

run on the VisionFive. Follow the steps below according to your operating system.

Start by downloading the Fedora image from here.
