Pick a Component Category and Find the Best Component for Your Needs

Often you might know what you want to do but are uncertain how to do it, or what could be the best component for your use case.

Choosing and Comparing

For almost anything there is a rich choice of Breakout Boards and Components available. I have categorized them for you, show-case them and share the differences, test results, and true specs.

  • Power: All about Power-related devices. I cover voltage and current regulators, constant voltage and constant current, batteries, charger, BMS (battery management systems), and I’ll cover the best ways of actually measuring voltage and current.


Many modern DIY projects these days use microcontrollers.

Whether you are into Arduinos or would like to finally understand the differences between ESP8266, ESP32, Wroom, or whatnot, the Microcontrollers section has you covered.


Please do leave comments below. I am using utteran.ce, an open-source and ad-free light-weight commenting system.

Here is how your comments are stored

Whenever you leave a comment, a new github issue is created on your behalf.

  • All comments become trackable issues in the Github Issues section, and I (and you) can follow up on them.

  • There is no third-party provider, no disrupting ads, and everything remains transparent inside github.

Github Users Yes, Spammers No

To keep spammers out and comments attributable, all you do is log in using your (free) github account and grant the permission to submit issues on your behalf.

If you don’t have a github account yet, go get yourself one - it’s free and simple.

If for any reason you do not feel comfortable with letting the commenting system submit issues for you, then visit Github Issues directly, i.e. by clicking the red button Submit Issue at the bottom of each page, and submit your issue manually. You control everything.


For chit-chat and quick questions, feel free to visit and participate in Discussions. They work much like classic forums or bulletin boards. Just keep in mind: your valued input isn’t equally well trackable there.
