This video is part of our ongoing tutorial series on designing IoT hardware from scratch, where we are building a custom telematics board featuring:
ESP32-C6 for Wi-Fi & BLE
STM32 MCU as the main controller
Quectel EC200U for 4G LTE connectivity
microSD card logging
Dual CAN bus interface for automotive-grade data capture
We're not just explaining theory — we're showing how each component, including resistors, fits into the bigger picture of professional-grade embedded system design.
🔧 Whether you're prototyping a smart device or building a production-ready board, this series covers the core principles of hardware design with a focus on practical, real-world implementation.
