EBYTE has released a new industrial-grade SBC powered by the Allwinner A527/T527 processors — combining dual camera support, AI acceleration, and Raspberry Pi form factor compatibility.
Designed for embedded, IoT, and smart commercial systems, the board mirrors the layout of the Walnut Pi 2B, and to a lesser extent, the Orange Pi 4A, while adding advanced features like dual 4K display output, 2 TOPS NPU, and a PCIe 2.1 interface for high-speed expansion.
Core Specifications
The board comes in multiple versions based on Allwinner A527 (commercial) and Allwinner T527 (industrial) SoCs, featuring an octa-core Arm Cortex-A55 CPU, a RISC-V co-processor, and an optional AI NPU.
Processor
- CPU: 8x Arm Cortex-A55 cores (4x @ 1.8/2.0 GHz + 4x @ 1.42 GHz)
- RISC-V Core: XuanTie E906 up to 200 MHz
- GPU: Arm Mali-G57 MC1 (OpenGL ES 3.2/2.0/1.1, Vulkan 1.1–1.3, OpenCL 2.2)
- DSP: HiFi4 @ 600 MHz for advanced audio processing
- AI Accelerator: Up to 2 TOPS NPU (T527MN variant only)
Memory and Storage
- RAM: 2GB or 4GB LPDDR4
- Storage:
- MicroSD card slot
- Optional 32GB eMMC (on T527MN variant)
- SPI NAND (64Mbit) on select versions
Display and Camera Capabilities
The board supports dual 4K displays and dual cameras, giving it strong potential for AI vision, kiosk, and smart surveillance applications.
- HDMI 2.0 (4K@60fps for 2D, 4K@30fps for 3D)
- 4-lane MIPI DSI interface (1920×1200@60fps)
- Dual display output via HDMI + MIPI DSI
- 2× 4-lane MIPI CSI camera connectors (compatible with Raspberry Pi cameras, 2 Gbps per lane)
Connectivity and Expansion
Networking and connectivity are solid for an industrial SBC:
- Gigabit Ethernet (RJ45) with integrated transformer
- Wi-Fi 4 (802.11b/g/n) and Bluetooth 4.2 (BLE) via onboard Ebyte module
- PCIe 2.1 x1 (5 Gbps) for add-on cards
- 4× USB 2.0 ports
- USB Type-C for 5V power and USB device support
Additionally, a 40-pin Raspberry Pi-compatible GPIO header allows developers to use existing Pi accessories and HATs.
GPIO functions include: SPI, I2S, I2C, CAN, UART, PWM, GPIO, VIN, and ADC.
Additional Features
- Audio: I2S2 for codec connection + onboard audio
- Buttons: Power, Reset, and Download
- Indicators: Dual-color LED (Power & Status)
- RTC battery holder (1.25mm 2-pin)
- ESD & TVS protection on all interfaces
- Serial debug port
- Watchdog timer
Dimensions: 85 × 56 mm — same as the Raspberry Pi 5
Power Supply: 5V DC via USB Type-C
Operating Temperature: −25°C to +85°C (industrial range)
Software Support
EBYTE provides Linux-based software stacks for all models, including:
- Linux kernel 5.15.147 with U-Boot 2018.07
- Debian, Buildroot, and Qt environments
- Support for Wayland and Python SDKs
Developers get full SDK source code (SPL, U-Boot, kernel, and BSP drivers) for GPIO, display, CAN, PCIe, audio, and more.
The T527MN variant adds AI framework support for TensorFlow, Keras, ONNX, and Caffe, making it ideal for AI-enabled edge computing.
EBYTE also provides tools such as PhoenixSuit and PhoenixCard for firmware flashing, plus YUV Player and CH341SER drivers.
The platform undergoes rigorous reliability tests — including 72-hour burn-in, 3000 power cycles, and full I/O stress validation.
