TTB #31: How to Select the Right Microcontroller
Choosing the right microcontroller isn't about buying the fastest or most expensive option. It's about selecting a platform that meets your project's requirements while remaining easy to develop with. In this guide, I share the process I use when designing real embedded systems, from evaluating peripherals and voltage compatibility to considering documentation, development tools, and long term availability. You'll also find practical examples from my own projects, common mistakes to avoid, and recommendations for beginners and experienced makers alike. Whether you're building an IoT device, robot, drone, or home automation project, this guide will help you choose confidently.

TTB #30: This is Why We Do QC
Ever wonder what goes into manufacturing a reliable microcontroller? Inside the PTSolns workshop, quality control (QC) is everything. In this post, we take you behind the scenes of our Thorough hardware testing procedure for the Nano Flip 3V3 fresh off the production line. Discover our multi-step electronics inspection process, from burning the custom ATmega328P bootloader and flashing firmware sketches to catching physical PCB manufacturing defects. Learn how we track failure rates, optimize circuit board performance, and handle defective hardware to ensure every microcontroller we package delivers top-tier reliability for your electronics projects.
