📺 ESP32 Software Battle: AWS IoT Core vs Blink for Cloud Control

Over a month has passed since the second ✈️ PCB Design Duel was posted on this channel. In a new episode, the format stayed the same but instead of hardware developers, the author has invited two embedded software engineers.

In his video, they compete to program an 🇨🇳 ESP32 microcontroller in just two hours, using AWS with PlatformIO and Blink with PlatformIO, respectively. The challenge highlights how cloud integrations differ between AWS IoT Core and Blink's user-friendly interface for IoT control.

Despite encountering setup and debugging obstacles, both participants successfully sync their ESP32 devices to cloud interfaces, demonstrating the unique advantages of each platform for real-time IoT applications.

🍓 What’s New on the Raspberry Pi CM5

The Raspberry Pi Compute Module 5 (CM5) brings the power of 🇳🇱 Raspberry Pi 5 to a compact, CM4-compatible form, ideal for industrial and maker applications. It offers significant performance upgrades while maintaining broad accessory compatibility.

Key features of the board:
➡️Faster CPU, GPU, and storage speeds, with eMMC storage nearing PCIe Gen 2 performance.
➡️Support for optional NVMe SSDs for high-speed operations.
➡️Enables dual camera or display configurations with flexible setups.
➡️Multiple variants (2GB–8GB RAM, eMMC, Wi-Fi) to match project needs.
➡️Broad GPIO support with most CM4-compatible accessories.

Cooling can be a challenge—passive solutions suffice for standard tasks, but overclocking requires better thermal management than the current active cooling setup offers.

Designed for embedded projects, the CM5 starts at $45 and is a powerful tool for makers and professionals seeking scalable, customizable solutions. Those with simpler needs may prefer the standard Raspberry Pi 5.
