- OpenWrt as an Enterprise Edge Gateway
OpenWrt turns commodity routers into programmable edge gateways with package management, firewall control, and VPN support. Custom…
- Zephyr RTOS vs. FreeRTOS
Zephyr and FreeRTOS both run on microcontrollers, but they target different projects. Zephyr offers a broad, standardized ecosyste…
- MQTT Cluster Scale Architecture
MQTT is the default protocol for constrained devices because it is lightweight and supports publish-subscribe semantics. Scaling t…
- Over-The-Air Embedded Updates
OTA updates keep deployed devices patched, but a failed update can brick hardware you cannot reach. A safe design uses signed imag…
- Edge AI on Microcontrollers
TinyML runs small models directly on microcontrollers, enabling vibration, audio, and vision inference without sending raw data to…
- IoT Security Hardening
IoT devices fail security in predictable ways: default credentials, exposed debug interfaces, unsigned firmware, and no update pat…
- Home Assistant Core Optimization
Home Assistant runs local automation across hundreds of integrations, and performance depends on database choice, recorder setting…
- Industrial IoT Protocol Translation
Factories run on Modbus, CAN bus, and other fieldbus protocols that predate IP networking. Bridging them to modern systems require…
- LoRaWAN Infrastructure Management
LoRaWAN provides long-range, low-power connectivity for sensors spread across wide areas. Running a private network means managing…
- Power Management in Embedded Linux
Battery-powered Linux devices live or die by idle power. Most of the budget goes to wake-ups, radios, and peripherals that never t…
