What Is an Embedded SBC?
An Embedded Single-Board Computer (SBC) integrates CPU, GPU, memory, storage, display interfaces, and rich I/O on a compact PCB to run a complete operating system. Compared with discrete MCU + peripheral designs, an SBC shortens development cycles, lowers software risk, and offers consistent multimedia and connectivity performance. For OEM devices—from smart HMI panels and industrial gateways to medical instruments—an SBC provides a proven, upgradeable computing core while the product team focuses on the application, enclosure, and certification.
- Integrated display stack: MIPI-DSI/LVDS/eDP, RGB, backlight control, and touch (I²C/USB) are ready for panels from 3.5" to 15.6" and beyond.
- Rich I/O: GPIO, UART, SPI, I²C, PWM, CAN, USB, Ethernet, PCIe, audio, camera, and storage (eMMC/SD/SSD).
- Production-grade OS: Android or Linux with a board support package (BSP), drivers, and SDKs.
- Lifecycle support: long-term component availability and sustained software maintenance for industrial deployments.
SoC Platforms at Rocktech
Rocktech designs and manufactures embedded boards around modern ARM SoCs with strong multimedia and power-efficiency. We focus on two mature ecosystems—Rockchip and Allwinner—to balance performance, BOM cost, and availability for different product tiers.
Rockchip Lineup (Performance & Multimedia)
Rockchip SoCs are known for capable GPUs, efficient video engines, and robust Android/Linux BSPs. They are ideal for interactive HMI, edge AI vision, and rich multimedia.
- PX30 (Quad Cortex-A35): Low-power workhorse for 24/7 HMI panels, kiosks, energy meters, and medical auxiliaries. Stable, cost-effective, with excellent compatibility for small-to-mid-size TFTs.
- RK3566 (Quad Cortex-A55 + Mali GPU): Balanced CPU/GPU, 4K decode, MIPI-CSI/DSI and LVDS options. Great for smart control panels, Android gateways, and media-rich signage.
- RK3576 / RK3588 Family: Higher compute budgets, multi-display output, powerful NPU/GPU pipelines. Suitable for advanced dashboards, multi-camera analytics, and AI-edge terminals.
Allwinner Lineup (Cost-Optimized & Mature)
Allwinner platforms emphasize cost/performance and steady availability—perfect where BOM and power are tightly constrained but a full OS and multimedia are still required.
- A64 / A133 Class: Proven quad-core designs for value-oriented Android/Linux HMIs, barcode terminals, and appliance interfaces.
- Other families on demand: For special thermals, longevity, or interface needs, we tailor the SBC around the most suitable Allwinner part to reach your target price and timeline.
Why These Two Ecosystems?
- Stable BSPs & toolchains: mature kernels, vendor patches, and documentation shorten bring-up.
- Display & touch depth: reliable DSI/LVDS pipelines, panel timing tuning, and touch IC integrations (I²C/USB) reduce risk.
- Longevity: industrial availability roadmaps and second-source options help you pass audits and maintain supply.
Operating Systems: Android vs. Linux
Android for Embedded HMI
Android brings a mature UI framework, touch-first UX, and a vast developer ecosystem. It excels at graphically rich applications, fast animation, and multimedia. With kiosk/launcher modes, device policy control, and OTA pipelines, Android becomes a reliable embedded runtime—without consumer bloat.
- UI/UX: Material components, GPU acceleration, vector graphics, smooth transitions for premium panels.
- Media & camera: Hardware codecs and camera stacks simplify signage, playback, and vision UIs.
- App delivery: AOSP or managed app stores; CI/CD signing and private distribution.
Linux for Industrial Control
Linux offers determinism, composability, and deep kernel-space control. Using Debain/Ubuntu or Buildroot/Yocto, teams trim userland, lock down services, and expose only what the device needs—ideal for headless control, protocol gateways, and long-uptime appliances.
- Fine-grained footprint: tune kernel and rootfs to match your security and boot-time goals.
- Industrial protocols: CAN, RS-485/Modbus, MQTT, OPC-UA, and custom middleware.
- Ops & maintenance: secure shell/device management, A/B updates, offline field service images.
How to Choose
- Choose Android if your product is UI-intensive (multi-touch HMI, animated dashboards, rich media) and benefits from Java/Kotlin app velocity.
- Choose Linux if you need tight control, minimal footprint, protocol-heavy services, or long unattended operation.
- Hybrid stacks are common: Android for the HMI layer with a Linux service plane—talk to us to pick the right split.
