    TTB #15: [Guest Post] Getting Started with the ESP32 microWatt Making IoT Projects

    PTSolns partnered with Jameco Electronics to create a two-part guest blog series, “Getting Started with the ESP32 microWatt.” Part 1 covers installing the Arduino IDE, setting up the ESP32 microWatt development environment, and running your first sketches to confirm hardware and software communication. Part 2 expands into using the ESP32 microWatt’s built-in Wi-Fi, versatile GPIO pins, and sensor integration to build practical IoT applications. From weather stations to smart home projects, this beginner-friendly guide provides step-by-step instructions to help makers, engineers, and educators confidently work with the ESP32 microWatt microcontroller for electronics prototyping, embedded systems, and connected device development.

  • Testing the 3.3V Pin of Popular Nano Dev Boards

    TTB #14: Testing the 3.3V Pin of Popular Nano Dev Boards

    In this post, we compare the 3.3V pin performance of three Nano-style development boards under two load conditions: 50 mA and 100 mA. We measure voltage quality and temperature rise using a precise resistive load, oscilloscope, and thermal camera. Each board is scored across five categories, including current rating, voltage quality, and temperature rise. Despite similar pinouts, the boards show major differences in performance. One board stands out with superior voltage regulation, higher current capacity, and lower temperature rise under load, making it the top choice for reliable 3.3V rail applications.

  • PCB Trace Width Calculator with Plot

    TTB #13: PCB Trace Width Calculator with Plot

    The PCB Trace Width Calculator uses IPC-2221 to estimate trace width, resistance, voltage drop, and power loss for internal and external PCB layers. It supports unit selection, graphing, and quick approximations—ideal for early-stage design and educational use.
