DshanPi-A1: A Feature-Packed RK3576 SBC with HDMI Input and Dual Gigabit Ethernet

The DshanPi-A1 is making waves in the single-board computer community as a versatile new platform powered by Rockchip's RK3576 octa-core processor. While it shares the same chip as the Bit-Brick K1 Pro, this board differentiates itself with a unique combination of features that make it particularly interesting for video capture, networking, and embedded applications.

RK3576 Performance at an Accessible Price

At the heart of the DshanPi-A1 is the Rockchip RK3576, an octa-core Arm-based processor that balances performance and efficiency. The chip features four Cortex-A72 cores running at 2.2 GHz for demanding tasks, paired with four Cortex-A53 cores at 1.6 GHz for power-efficient operation. Graphics are handled by the Mali-G52 MC3 GPU, while a 6 TOPS NPU provides dedicated acceleration for AI and machine learning workloads.

The board is available in two configurations: a base model with 6GB LPDDR4 RAM and no onboard storage for $83, or an upgraded version with 8GB RAM and 64GB eMMC flash storage for approximately $130. Both models include a microSD card slot for additional storage expansion.

Dual Gigabit Ethernet and HDMI Input: The Standout Features

What truly sets the DshanPi-A1 apart from other RK3576 boards is its impressive array of video and networking capabilities. The board features two Gigabit Ethernet ports, making it ideal for networking applications, routers, or any project requiring redundant network connections.

However, the most distinctive feature is the HDMI input port. Unlike typical single-board computers that only offer HDMI output for display purposes, the DshanPi-A1 can function as a video capture device. This opens up possibilities for creating custom video recording setups, live streaming solutions, or multimedia processing systems. The HDMI input is complemented by two 4-lane MIPI-CSI camera connectors, supporting up to four cameras simultaneously for complex video processing applications.

Comprehensive Video Output Options

The board doesn't skimp on display capabilities either. In addition to the HDMI input, it offers:

• HDMI 2.1 output for connecting to modern displays and TVs
• USB Type-C with DisplayPort Alt Mode support
• 4-lane MIPI-DSI connector for direct LCD panel connections

This versatility makes the DshanPi-A1 suitable for both traditional desktop computing scenarios and specialized embedded display applications.

Connectivity and Expansion

Beyond its video capabilities, the DshanPi-A1 provides robust connectivity options:

• USB: Two USB 3.0 Type-A ports, one USB Type-C OTG port, and a dedicated USB Type-C port for power
• Wireless: M.2 E-Key slot for adding Wi-Fi, Bluetooth, or other PCIe 2.0 x1 devices
• GPIO: 40-pin header compatible with Raspberry Pi accessories and HATs
• Audio: 3.5mm audio jack for sound output
• Power Management: RTC battery interface and fan power supply for extended operation

Software Support and Development

The DshanPi-A1 supports several Linux-based operating systems right out of the box, including Fedora, Armbian, Buildroot, and OpenWrt. This broad software compatibility ensures developers can choose the environment that best suits their project requirements, whether that's a full desktop Linux experience or a lightweight embedded system.

Practical Applications

The combination of features makes the DshanPi-A1 suitable for numerous applications:

• Video Capture and Processing: The HDMI input and multiple camera connectors enable custom video recording and streaming solutions
• Networking Appliances: Dual Gigabit Ethernet ports make it ideal for building routers, firewalls, or network monitoring devices
• Media Centers: HDMI input and output capabilities allow for creating advanced media processing systems
• AI Edge Computing: The 6 TOPS NPU provides hardware acceleration for computer vision and other AI workloads
• Industrial Control: GPIO headers and robust connectivity make it suitable for industrial automation projects

Physical Design and Build Quality

The board measures 97 x 77mm (approximately 3.8" x 3"), making it compact enough for embedded applications while still providing ample connectivity options. The inclusion of a recovery key and two user keys suggests the board is designed with security and system management in mind.

Availability and Pricing

Currently available through AliExpress, the DshanPi-A1 offers compelling value for its feature set. The base model at $83 provides access to the RK3576 platform with 6GB RAM, while the $130 configuration adds storage and additional RAM for more demanding applications.

Conclusion

The DshanPi-A1 represents an interesting evolution in the single-board computer market. While many SBCs focus on either computing power or connectivity, this board successfully combines both with its unique HDMI input capability. For developers and hobbyists working on video capture, networking, or multimedia projects, the DshanPi-A1 offers a compelling platform that stands out from the crowded SBC landscape.

The board's success will likely depend on community adoption and software support, but its hardware capabilities provide a strong foundation for a wide range of innovative projects. Whether you're building a custom video capture solution, a networking appliance, or an AI-powered edge device, the DshanPi-A1 offers the features and flexibility to bring your ideas to life.
