This concerns a USB A socket on a PCB.
Is there a standard or preferred orientation of the polarization tab, either up or down?
The picture shows one with tab towards the top

I’ve designed a fan control circuit using an N-channel MOSFET (STN3NF06L.) The fan operates at 12V, and I’ve isolated the 12V side from the 3.3V microcontroller side using an optocoupler (ACPL-W314-...

I want my code to be able to determine the direction of motion for the LIS2DE12 accelerometer. I did a test where I had the accelerometer on a breadboard (connected to the STM32) and logged the values ...

Just an example - STM32F722 has a few versions, but I'm talking about just the variance between two numbers: RET6 vs RET7. The former has a max operating temp of 85C, whereas the latter says 105C. ...

3 V signal (PWR-ENABLE) be enough to turn on this circuit?
The collector of Q3 will be at 11 V before switching is to occur.

I've come across multiple mentions of switches described as 1NO1NC.
They often described as having 2 options: ON/(OFF) and (ON)/OFF and from what I gather they have 3 terminals for wires: a NO ...

Like most computer hobbyists and programmers, I've amassed boxes of USB cables to connect USB, Micro-USB, and Mini-USB to chargers, computers, and gadgets. These cables are a mix of phone charger ...

I am relatively new here and I am confused as to the difference between Vrms and Vm. I would be obliged if someone can explain. (This in relation to 3-phase circuits would be even better)
My shot at ...

I have a cell phone battery that has the following written on one side:
3.7 V 1000mAh
Limited charge voltage: 4.2 volts
I understand that the first line means, that the battery will always give 3....

What is the difference between a latch and a flip-flop?
What I am thinking is that a latch is equivalent to a flip-flop since it is used to store bits and is also equivalent to a register which is ...

I know that electric vehicles have different performances depending on battery and motor, but it's not clear how electrical and mechanical units are related.
Will a 100V motor raise against slopes ...

I'm using RC5 encoding for my project.
I'm sending signals using RC5 Protocol. The transmitter is sending the signals correctly.
But on the receiver node, when I decode the signals, Library is unable ...
