The 74HC4051 Mux (spec is here: http://www.nxp.com/documents/data_sheet/74HC_HCT4051.pdf) has 8 input/output pins labelled Y, one output/input pin labelled Z, three digital selectors S0, S1, S2, and ...

I've been on this site now a couple of months and I notice various symbols used for MOSFETs. What is the preferred symbol for an N Channel MOSFET and why?

I am trying to get a handle on some electrical circuit diagrams I've been encountering as I try to get back into electronics and building electronic gadgets. I've encountered a number of terms for ...

On this page, the two versions of this gyro/accelerometer IC have two different Logic Supply Voltages. What is the VDD voltage? Why would one version of the chip also have an option to make the ...

I have read from some book that: "The voltage quantity symbol V sometimes has subscripts to designate the two points to which the voltage corresponds. If the letter a designates one point and b the ...

I have a HMC5883L and its pins are labeled SDA, SCL, DRDY, VIN, and GND. SO I am following this tutorial and it has a VCC pin but mine doesn't have it so I was wondering if VIN is the same as VCC ...

I am creating a library component for KiCAD using a convenient online app at: http://kicad.rohrbacher.net/quicklib.php. The component I am making is the Microchip PIC24EP512GU814 in LQFP http://www....

Hopefully I'm not doing anything illegal, I posted a very similar question a few days ago, but this one is different. Here is what I've been working on the past couple days, trying out different ...

My question is to find whether there can be a definitive answer to this particular part. I have Cypress MBR3002 IC which has two power pins labelled VCC and VDD. I got a question from my ...

I have an USB-UART cable. The connectors listed are Red VCC, Black GND, Green TXD, White cable RXD. I want to connect it to a Alfa Hornet-UB board (http://www.youtube.com/watch?v=i58XOF4Rfc4) with ...

I recently created my own breakout board for a STM32F030R8T6 MCU. The attached image shows the PCB that I designed for it. There are no components, only top copper tracks that get connected to header ...

In ATmega32u2's reference manual, there's a diagram for USB-powered application like shown below. Should I, or should I not, connect the GROUND to VSS/UVSS line? And why? If not, then what to do, ...

What are Vcc and GND on a shift register? I thought that I had to provide a positive voltage to the IC via the Vcc, but turns out that I can operate my shift register without powering the Vcc. ...

What is the correct voltage terminology for VDD and VSS? I've been installing a Winstar WEH001602D OLED and was struggling until I realised that it appears to have pins 1 and 2 reversed compared to ...

I'm following the design of a circuit requiring a power supply to provide something the author calls virtual ground, \$V_{gnd}\$. The circuit look like this: However, I'm using KiCad for the design ...
