The Linux Advantage for Industrial Automation
Why leading engineers choose Linux-RT over traditional RTOS or PLCs
Real-Time Determinism
Linux-RT kernel with PREEMPT_RT patch delivers task cycle jitter < 50µs. Hard real-time performance for motion control, high-speed data acquisition, and deterministic I/O response.
Unlimited Software Ecosystem
Run Node-RED, Python, C/C++, Docker, K3s, InfluxDB, Grafana — millions of open-source packages available. No vendor lock-in. Use what works for your application.
No Runtime License Fees
Pay for hardware once. No per-point, per-feature, or per-core licensing. No surprise annual fees. Total cost of ownership dramatically lower than proprietary PLCs or RTOS.
Future-Proof & Secure
Long-term supported (LTS) kernel. Container isolation (Docker/K3s) for application security. Standard security updates via apt/dnf. Your code stays yours — no hidden IP transfer.
✅ POSIX Standard APIs✅ Yocto / Debian / Ubuntu Support✅ 10+ Years Kernel Maintenance✅ Global Developer Community
Real-Time Foundation
Linux-RT Real-Time Kernel
BL335 is built on Linux-RT (PREEMPT_RT) real-time kernel, delivering deterministic task scheduling with < 50µs jitter. Hard real-time performance for motion control, high-speed I/O, and time-critical data acquisition.
✅ Deterministic response — no unexpected latency spikes
Web-based graphical configuration tool for ARM devices. Set up WAN/LAN, Wi-Fi, 4G with auto failover. Monitor system load, manage firewall, update firmware, and control hardware watchdog — all without command lines.
Embedded WebIDE for remote development & maintenance. Edit code, manage files, run terminal commands — all from any browser. Built-in AI assistant (DeepSeek etc.) for code explanation, bug detection, and script writing. Perfect for on-site debugging.
