Simple way to make hardware revision (REV1, REV2, REV3) using only one ADC pin, that helps to easy identify board version using MCU firmware, which give a change to easy maintain all board revisions taking into account all the device schematic changes .

The only possible and correctly working way to extract (export) .step model from the EasyEDA footprint.

Load switches are used for power control of any loads, typically it's used to fully enable or disable power of integrated circuits (chips) to achieve low power consumption in sleep mode.

Here is simplest high-side load switch on discrete components, that can be used instead of special ICs. Firstly some work simulation in MicroCap and then real testing with board.

Using slider – simple but powerful instrument for debugging and developing.

Small instruction of using STM32CubeMonitor to write (change) value to the variable (RAM address).

This short article help you to easily handle footprints courtyard (outline) overlap (overlay) clearance violations in KiCad by writing custom rule exceptions for specific components, to get 100% clear DRC without registration and SMS ?.

This short note will help you get rid of ERC violations easily and in the most right way ?.

Simple way to get binary and hexadecimal output files (firmware) from STM32CubeIDE project.

Fusion 360 is an impressive easy-to-use, intuitive and beautiful mechanical CAD but it cloud-based, so who knows what could be tomorrow ??.

So now we export all projects data in different formats to get reverse copy (backup) or switch completely to another CAD, such as FreeCAD ⚒.

How to use your electrical bike battery as power supply system (power bank) to charge you laptop, smartphone and have an LED light ☀? Here is an full assembly manual with chosen parts for build a custom high-power and high-energy power bank.

Compendium of information of use LEDs with reverse mounting techniques ?.

Easiest and most properly way to bunch changing of via hole sizes in Altium Designer.

If paths to your library files doesn't specified in the STM32CubeIDE (Eclipse) project properties (both source and include) the project will be unable to compile?.. Here is clear steps to solve this problem with example ?.

Utterly simple and useful circuits for protect your device against incorrect power supply polarity (reverse polarity) connection:

• High Side (based on P-Channel MOSFET)
• Low Side (based on N-Channel MOSFET)

This really simple thing can save the life of your electronic device, without taking up much space, thanks to modern miniature transistors.
