measure the dielectric constant of the ESP32-Wrover module

Will it be possible to measure the dielectric constant of the ESP32-Wrover module to know if it is FR4 or not? In case, one wants to know the characteristics of the original PCB antenna

Why isn't my ESP8266 RFID Reader Providing Expected Output on the Serial Monitor?

"Hey team, I've successfully uploaded the RFID reader code to my ESP8266, and the hardware connections seem correct. However, I'm not getting the expected output on the Serial Monitor. The loop is running, but I'm not detecting RFID tags or seeing UID information. Any insights on what might be causing this issue would be greatly appreciated!"

how to make proximity-activated locks except for ultrasonic sensors

Hey guys, any ideas on how to make proximity-activated locks except for ultrasonic sensors? We're trying to make a lock that is activated based on the signal distance of a receiver to the transmitter.

EMI EMC Testing

Here is the question that I get asked a lot. Can you do the test for EMI and EMC on the software itself prior so that we don't have to do physcial testing as much and pass all the standards so that the product launch happens faster?? To everyone in the community, what are your thoughts?...

How do I create a 50 ohms Impedence Trace

Recently designing a PCB board that has four layers, am using SIM7020E chip from SIMCOM, a cellular Chip. The Datasheet said i should Use a 50 ohms trace line on my PCB for the antenna Pin side in order to match the circuit. What will i do to get 50 ohms trace value for the four layers board. Are there any tools or steps needed to take ?

Slow rise time on SD_CLK causes boot failure

Hello everyone, I would like to consult on an issue I’m having with the SD_CLK signal of my board. The board is a UPnP music server / router and it boots from an SD Card to load the Uboot, Linux Kernel, and Linux user space. There are already several boards manufactured. There is one board that fail to boot from the SD Card outright and one board that initially worked fine but failed at a later time. The rest of the boards worked fine, but it is concerning that a failure might also happen in the future. Considering all is same (hardware / binary image loaded), there is a significant delay in the rise up time on SD_CLK signal of the failing board....

Is this possible?

i have a cheap controller that i have had for a while but never used because it was cheap, but when my normal daily driver controller started malfunctioning, i thoght that maybe i could turn it into a better controller. it uses standard usb3, and im wondering if i could solder a usb 3 wired to wireless adapter but just the pins needed and then solder a battery? is this possible? im not that good so maybe its really hard.

Low-cost but still excellent oscilloscopes for SOHO

After my contribution to the LinkedIn collaborative article https://www.linkedin.com/advice/0/how-do-you-choose-right-oscilloscope, I was asked multiple times for an oscilloscope recommendation. Believe it or not, I have used a simple 100 MHz 1-Ch Siglent SDS1102CML for about 11+ years. Have I ever needed a better one? Sure, I have but I always find a way how to get my results. My tips for low-budget scopes:...

Implementing Independent Speed Control for Dual DC Motors with Arduino and H-Bridge Motor Driver

morning ! I'm currently working on an Arduino project where I'm trying to control the speed and direction of two DC motors simultaneously. I've connected the motors to an H-bridge motor driver, and the basic forward and backward motion is working fine. However, I'm struggling to implement speed control for each motor independently. Can anyone guide me on how to achieve individual speed control for both motors using Arduino?...

How to choose component-to-edge clearance while designing PCB?

When designing my PCB Boards i normally see that most manufacturers always say we should give a certain amount of space for copper and Board Edge Clearance. What is the main purpose of giving the space, how does it affect the design.

What’s the best PCIe Gen 5 clock source for board-board data transfer over a backplane?

I’m designing a high-frequency control system based on a Xilinx FPGA-based board that connects to multiple FPGA daughter cards over a PCIe switch and backplane using PCIe 5. Does anyone have experience designing a similar system? Any recommendations for the clocking architecture and clock types in this application? I’m looking to minimize jitter but not sure separate reference clocks alone like I’ve used in the past will suffice with the PCIe 5 bandwidth and frequencies. Any advice is appreciated. Thanks....

Is Putting ESD Protection Diode Critical in a USB Line?

Am designing an electronics board, i have limited space in my board so I want to confirm if putting an ESD IC is necessary, can i do away with it. If i dont add it are there chances that my design will not work.

What is the Importance of Copper Thickness in PCB Design

What does PCB copper thickness Mean and why does it matter during the design process? Why are there different sizes such as 0.5oz, 1.0oz, and so on, what are their importance, and do they have a specific application use case? How do it after my design during and after the manufacturing process and is there a certain standard thickness used among designers? Your insight will be helpful to me. Thank You
