Technical Specifications

GPIO and Expansion

The Orange Pi 3B features a 40-pin GPIO expansion header, allowing connection to compatible electronic components and external peripherals.

Depending on the selected pins, operating system, and software configuration, supported interfaces may include:

• Digital GPIO input and output
• UART serial communication
• I2C communication
• SPI communication
• PWM signals

The GPIO header can be used to interface with sensors, communication modules, motor controllers, and other embedded electronics.

Important: Orange Pi GPIO signals operate at 3.3V logic levels. Do not connect 5V signals directly to GPIO pins without suitable level conversion.

Storage Options

1. microSD Card

Supports operating system installation and data storage using a compatible microSD card.

2. eMMC Storage

Supports optional eMMC storage for embedded applications.

3. M.2 SSD

Provides an expansion option for compatible solid-state storage devices.

Storage accessories and SSD compatibility should be checked before installation.

Important Notes

• This product is the 2GB RAM version of the Orange Pi 3B.
• A stable 5V/3A USB-C power supply is recommended.
• A compatible microSD card or other supported storage device is required to install an operating system.
• GPIO pins use 3.3V logic and are not 5V tolerant.
• Raspberry Pi accessories and HATs are not automatically compatible, even when the physical header layout is similar.
• NVMe/SATA storage support depends on the board revision, adapter, and software configuration.
• Some operating systems may not support all hardware features.
• A suitable cooling solution is recommended for sustained high-load operation.

Package Includes

• 1 × Orange Pi 3B Single Board Computer (2GB RAM Version).
