Python is everywhere. Its capabilities continue to grow. Not only can you create simple scripts, but you can create full-blown applications with it. The core has been scaled down to run on 32-bit microcontrollers like the ESP32 and Adafruit Feather M0. You can even use Python engineer modules to design stuff like circuits. There are electronics Python modules that create schematics, simulate circuits, and make solving math a cinch. Here are some of the modules I found that make Python usable for (electronics) engineering.
Up front, make sure you have a functioning Python environment. Update the package manager “pip” since all of these electronics python modules rely on it. Speaking of dependences, you may need to also install third-party libraries for some of them. From what I can tell, these all should be platform independent. However, I only tested these electronic modules with 64-bit Windows.

With the introduction of the Raspberry Pi 4, I dug into the announcement and datasheet while waiting for mine to arrive. Well, “datasheet” might be an exaggeration, but there is a list of the Raspberry Pi 4 tech specs available. That link gives a bullet item list of the main specs. In this post, I focus on these four:
There is a lot of very cool stuff on this $35 board. (Amazing they have kept that price point!) Or even the 4 GB $55 board. Adding Bluetooth 5, H.265 AND H.264 decoding, USB-C connector (Power), and changing the SoC to a 28 nm process are all significant improvements.
But, being an engineer and a person on the Internet, I am required to nitpick, and armchair engineer this (now) released product (that I haven’t touched yet.) Without doubt there will be a number of benchmarks posted along with the release of the Pi 4. And I expect many of those only benchmark individual components. For example, I already saw graphs on the Gigabit Ethernet speed and USB 3.0 throughput, but not at the same time. As you will see in my datasheet evaluation, using two USB devices at the same time has a performance penalty.
