At Embedded World 2025, Electromaker caught up with James from Raspberry Pi to get the lowdown on the newly released Compute Module 5 (CM5) — a drop-in replacement for CM4 with powerful new upgrades.
🧠 Built around the RP1 chip (same as in the Raspberry Pi 5), CM5 brings USB 3.0, native PCIe, and a more streamlined I/O configuration. It’s designed to fit directly into existing CM4 carrier boards, with added performance and flexibility.
But it’s not just a maker story.
💼 James reveals that 70–75% of Raspberry Pi sales go to industrial clients — from robotics and factory automation to airport digital signage. With no price tiering and wide availability, Raspberry Pi continues to blur the line between prototyping and deployment.
🛠️ Plus, with CM5’s advanced performance in a compact form factor, you can now power full desktop-class applications in a footprint smaller than a matchbox.
🚫 No Pi 6 scoop here — but James hints at continued improvements in both the Pico microcontroller line and Raspberry Pi’s industrial offerings.

⚡ Understanding Charge: The video explains the concept of electric charge, its properties, and its importance in the study of electrical circuits. 📊 Basic Electrical Components: Key components such as voltage, current, resistance, and resistors are introduced, laying the groundwork for circuit design. 🔌 Circuit Types: The instructor discusses series and parallel circuits, emphasizing their properties and applications. 🛠️ Practical Application: A small practical exercise is mentioned to reinforce the theoretical concepts covered. 🔬 Atomic Particles: The video highlights the roles of protons, neutrons, and electrons, particularly focusing on their charges. ⚖️ Positive and Negative Charges: The instructor discusses the arbitrary assignment of positive and negative charges to particles, clarifying common misconceptions. 🌐 Foundation for IoT: The knowledge gained from understanding these basics is crucial for anyone looking to advance in the field of IoT. Key Insights ⚡ Charge as a Fundamental Property: Electric charge is a fundamental property of particles that determines their interactions through attraction or repulsion. This concept is crucial in electronics and IoT applications, as it influences how components interact within a circuit. The instructor emphasizes that while charge cannot be measured by weight, it can be felt through its effects, highlighting the importance of conceptual understanding in practical applications.
🔌 Importance of Basic Electrical Components: A solid grasp of basic electrical components such as voltage, current, and resistance is essential for anyone venturing into electronics or IoT. The instructor outlines how these components interplay in circuits, forming the backbone of circuit design. Understanding these relationships is vital for troubleshooting and designing effective electronic systems.
📊 Understanding Circuit Designs: The differentiation between series and parallel circuits is a significant focus. Series circuits involve components connected end-to-end, sharing the same current, while parallel circuits have components connected across the same voltage source. This distinction is crucial for designing circuits that function correctly in IoT devices, where multiple components may need to operate simultaneously.
🛠️ Practical Learning Experiences: The instructor plans to introduce practical exercises to complement theoretical learning. Practical applications reinforce understanding and help learners apply the concepts in real-world scenarios, which is essential for mastering IoT technologies.
🔬 Role of Atomic Particles in Electricity: The video discusses the atomic structure, particularly focusing on protons, neutrons, and electrons, and their respective charges. This foundational knowledge is vital for understanding how electrical properties emerge at the microscopic level, which directly impacts the behavior of electronic components in circuits.
⚖️ Arbitrary Assignment of Charges: The instructor clarifies that the designation of positive and negative charges is somewhat arbitrary and based on historical experiments. This understanding demystifies the concept of charge and encourages learners to focus on the directional properties of charge rather than attaching emotional weight to the terms “positive” and “negative.”
🌐 Linking Concepts to IoT: The foundational knowledge of electrical circuits and charge directly links to IoT applications, where devices often rely on intricate electronic systems. The instructor stresses the importance of mastering these core principles to succeed in the evolving field of IoT, where understanding how devices communicate and operate is paramount for innovation and development.
