Topics

Pick your area. Beginners start with Zephyr RTOS. Experienced engineers jump straight to the topic.

⚡Active
Zephyr RTOS

Devicetree, Kconfig, drivers, BLE, power management — from first west build to production firmware.

🔌Coming Soon
Protocols

I2C, SPI, UART, CAN, MQTT — how they actually behave on real silicon, not just the datasheet.

🏭Coming Soon
Industrial IoT

Modbus, edge gateways, fieldbus protocols, rugged firmware patterns for industrial environments.

🤖Coming Soon
AIoT & Edge AI

TensorFlow Lite Micro, Edge Impulse, running inference on constrained MCUs.

📋Active
Reference

West commands, pin tables, I2C address lookup, Kconfig flags — the cheat sheets you actually need.

Latest from the Bench

Build diaries — honest accounts of what worked, what burned, and what the next board spin will fix.

Build diaries, lessons learned, and notes from the field — coming soon.
