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

I am trying to setup RAID in my BIOS using Intel RSTI have my BIOS SATA mode set to RAID mode: Intel rapid storage technology appears in my BIOS and I can access it: However I don't get the typical "Create RAID volume" option and I'm not sure why. The drives are set as AHCI controller instead of RAID. Not sure if that matters: I have the newest RST installed in Windows. But once again I don't have the option to Create RAID Volume:- I've updated my BIOS to the latest version- I've tried formatting the drives, as well as leaving them unformatted and unpartitioned  Any help in setting up RAID via the BIOS would be very much appreciated. Thank you

I am trying to develop a small inexpensive circuit that can convert the I2C output from a basic web camera element and encode the signal into PAL for use elsewhere. I have been looking at chips such as the AD725 from Analog devices, but am not entirely convinced of their suitability. If anyone knows of a simple solution to achieve this need I would really like to understand more. 

在英特尔®快速存储技术 （RST） 上使用 4TB 或更大的硬盘时存在数据丢失的风险，如何解决？ Is there a risk of data loss when using a 4TB or larger hard drive on Intel® Rapid Storage Technology (RST)? How to resolve this issue?

I am attempting to measure the power consumption of a server for an experiment I am running. Currently, I am looking at utilising a GPM-8213 Power Meter with a GPM-001 Power Meter Test Fixture. Would there be a more cost-effective way of doing this?  The voltage will be roughly 200-240V with a max current of 15A and I need to be able to connect the measurement devices to read into a separate PC, ideally suitable to be read into LabVIEW. Kind regards, Eoin   Kind regards, Eoin

I hope you all are having an awesome day.   I need a 3.3V power supply. I found the ID1117-33 chip but it only can supply 800mA, I need at least 1.5A (a higher amperage is better but not required ). The input voltage can be either 24V or 5V. The 5v power supply can handle 8A so it should not be a problem.   So I am wondering if anyone knows of such an animal?   

Hi,I want to add to design LED indication for Rx, Tx over pull up resistors, please refer picture for more detail. I do not know is this good idea or is better to add two dedicated outputs on MCU only for RX, Tx LED management.Please share pros and coins for solution on picture.Thanks.    

Hi! I'm working on a project and I need to make a platine that regulates different voltages. The output voltages I need are 1.8V(500mA) 3V3(1A) 5V(3A) 7V(2A) 12V(4A) and I don't know how to start. Do I need to choose one regulator for all of them or one regulator for each one. It would be nice that someone could help me. Thanks!

Hello everyone, I am doing a project about smart home, Infineon's ICE5AR4770BZS-based auxiliary SMPS for 15W high-efficiency home appliances. My question is why no need to add additional mosfets if we use Integrated ICE5AR4770BZS with Infineon? This solution is quite simple confuse me.  Thanks in advance.
