How do you approach debugging intermittent failures that might be related to a specific capacitor, like a Murata GRM series MLCC, experiencing temperature-dependent issues?

I am working on a Raspberry PI Python app I discovered something strange. The code does not detect a push button with my DVM connected to a test point, (the push button signal). Removing the DVM, the code works correctly.  Has anyone ran into this?

How does the EPM570T100I5N mitigate supply voltage noise, and what is its effective power supply rejection?

Morning. I am looking to bend the leads of an LED 90 degrees as per below. Can anyone tell me if this tool will be suitable for this? Thanks in advance. Richard

When I turn on the unit, the logic controller ( ItsyBitsy 32u4 - 3V ) does not boot up.It boots up just fine when I connect the USB, then runs properly even when the USB is disconnected!!! Yes, I checked the 3V rail and it is rock stable. Here is a screenshot of the schematic. Does anyone have any clue what is causing the problem?

I ask for help in the Arduino. forum and they do not have a clue what's going on. So am asking here. I have a stepper motor with a slotted encoder disk to tell the controller a home position using an ITR9608-F Opto Interrupter. The problem is it acts like it sees the slot when it does not. The is random and never in the same place.. Even with the sensor removed. It should constantly rotate with the sensor disconnected. So what could be causing this random rotationdis? I have tested the sensor out and in the circuit. Which makes me that controller is blow. Here is the schematic of the sensor. Also is a short video showing what I am talking about.   https://www.dropbox.com/scl/fi/09po77k418aa77dpa3bzi/DSCN0608.AVI?rlkey=oncfv5wxtgmfgf5w4tsvw1fzw&dl=0  

Can you recommend several replacement modules with stable performance and compatible with AFBR-2418TZ in the US market? details: https://www.emsfpga.com/productdetail/afbr-2418tz

SamacsysパーツファインダーのY14シリーズリレーについて，フットプリントと回路図の対応表が間違っている気がします コイル電圧の違いでY14H-1C-24DS，Y14H-1C-12DS，Y14H-1C-5DS，Y14H-1C-3DSがありますが，24DS以外のピン対応が間違っていると思います．こういう場合はどこに連絡するといいのでしょうか．

Hello, everyone! I am experiencing issues with my ATmega4809 microcontroller. The device suddenly stopped powering on, and I can't seem to identify the cause. I've checked the power supply and connections, and everything appears to be in order. Here are the details: Device: ATmega4809 Microcontroller Problem: Not powering on I’ve reviewed the datasheet and features for the ATmega4809, which you can find here. However, I couldn’t pinpoint any specific issue related to my problem. Has anyone else experienced similar issues with this microcontroller, or can anyone suggest potential troubleshooting steps? Any help would be greatly appreciated! Thanks in advance!

Our company currently has a lot of  LIS2DW12 and LIS2DH12 chips left. I feel that both LIS2DH12 and LIS2DW12 chips can be used in the circuit I am designing. Which one should I choose considering stability?

People have turned to SDR receivers if they want to explore radio communications, propagation or interesting radio signals from round the world. SDRplay RSP receivers are a popular, UK manufactured choice with good customer service and support. They cover 1kHz to 2GHz as a communications receiver when used in conjunction with free software supplied by SDRplay for Windows, MacOS, Linux and Raspberry Pi.  However thanks to Australian software developer Steve Andrew, they can also become excellent, calibrated spectrum analysers!  Steve has just launched a new version of his Windows-based Spectrum Analyser software which includes a tracking generator. There's a brand new Website with documentation and support information over on https://www.spectrumanalyser.co.uk/ The SDRplay RSP radios are available from RS Components - search SDRplay https://uk.rs-online.com/web/p/communication-wireless-development-tools/1935621

Good day,  Could you please help me with the code/s which will set the internal Osc. to 4MHz for a PIC16F628.  I used the following for a external Crystal for 4MHz.  Device = 16F628( pic16f628 pdf (STM32F105RBT6 STMicroelectronics (ichome.com)) )  Xtal = 4  All_Digital = True  Dim D As Word  Int: TRISB = %00000000  PORTB = 0  D = 150  Main: High PORTB.0  DelayMS D  Low PORTB.0  GoTo Main    Now I would like to use the internal Osc. to do the same as the external Osc.  Thanks very much

Hi, I'm looking for someone to check my design to see if it will work corectly. I've designed a relay board with an I2C interface and opto barrier in addition the power supply for the relays is independent. I would look forward to any feed back.   Chris
