pcb board

To add some context to this PCB layout, it's a four-layer board with a signal/ground/ground/signal stack-up. Since the inner layers are just reference planes, I didn't add any tracks and didn't see the need to include pictures of them. I used 0.4 mm tracks for nets that needed 5V, 0.3 mm for...

Hey all! I have some problems getting LP5036 led driver to work. Mainly, the most weird thing that is happening is that LEDs are turned on, even if IC is in reset. Meaning, as soon as I apply power, all LEDs turn on and I cannot control them via I2C interface. It looks like the OUT pins are...

This module use in Misubishi Fr-F840-11k VFD. Help me to find this module data .

Attached below are images of a 2-layer PCB layout I am currently designing. I have always had the habit of removing the ground plane underneath AC signals, but a more experienced PCB designer advised me that the removal of the ground plane should only be done near the connectors and high-power...

Hello there, I have a biosynex 0075n. I have disconnected battery connector and pumping motor from this PCB. Now can you guys help me to connect again? I want to connect disconnected battery and motor wire in this PCB

I'm totally new to PCB design. I'm struggling with this schematic circuit. Im trying to design its pcb layout using easyeda

I’m working on a personal project, and I could really use some help. I’m not an electrical engineer, so I apologize in advance if this is a basic question, but I’m a bit stuck. I paid someone to design a personal alarm PCB board for me. It’s similar to those cheap $10 alarms you find on Amazon...

I have this circuit schematic that i made in easyeda, i want to make the PCB Layout of it but only over the copper layer, and keep the components on the top components layer, but then i faced many problems , i want to make all the traces with the width of 1.2mm, beside the energy supply inputs...

I'm attempting to design a countdown timer that has 2 external 12v motors connected. I've added the usb type c connector and the usb converter to upload and edit code after printing board. the 3 buttons control the up/down/set of the timer and the 4th button is an override switch to supply both...

I am inspecting a few PCB designs and seeing some unusual features and would love help identifying them. In two of the attached images, there appear to be unfilled holes that go all the way through the 2-layer PCB. The placement of the holes doesn't seem to align with locations for optional...

I want to make a PCB (based on arduino NANO) for the management of a nanogrid consisting of a PV Solar and Wind Turbine and two storage batteries it has to contain current/voltage sensors along with ADC that send the data to arduino NANO for handling (decision making and Data storage in...

Hi All, I have created a schematic, see the attached screenshot. Now I am trying to simulate how it works in a digital Spice simulator (built-in DipTrace 5.0 beta). In general, it works almost reasonably. But there are strange signal distortions on some outputs of U3 on each...

Hi, This is my first time designing a PCB and I just wanted to check that I had done it correctly or if there's anything I can improve. The main focus of this design is to scale down Voltage into a GPIO entry on an MCU and then scaling back up the voltage coming out from the MCU to the OEM...

I have a 24V DC motor, but it does not work. I would like to find out which of the elements is most likely to be damaged and how to do it. From what I understand, the engine has a Hall sensor to set its position, but I don't know about the rest

I have designed my first pcb (4 layer) and I have a question about power planes versus power traces. I am using KiCad 7. I have tested the circuitry on a proto-board. I have a high current section (12-15 V dc @ 3-6 A for 100 - 500 msec), and a lower powerlogic control section (3.3V) - a DAC and...

I am working on my first PCB, and I am looking for some advice and direction. I am using KiCad 7, and so far it is working well. I have some more general questions regarding pcb fabrication and what options to choose. 1. I am considering PCBWay to make my 4 layer board due to cost and delivery...

Hello, I have a subwoofer that stopped working, one of these two parts has failed, the big one I have found as there are markings on it, the little one I have no idea, can anyone help me identify it?

Hey,guys!Today I find an annoying phenomenent of my PCB borad. A Chip,LT8316, and some components on the front of the PCB borad.A LED on the back.And chip controls the On-off of a NMOS to control the power supplied to LED.When I tested the borad alone,the LED almost brighted perfectly.But when I...

Hello everyone, It is my first time creating a PCB using Easy EDA, and I would like to add two RGB LEDs to my PCB. I am a little bit confused as to how to wire it. This is what I have now: I understand that to control the color of the LED, I need to send a different PWM duty cycle to each of...

This is an 8 function led strip light adapter and i want yhe circuit diagram of it can some one please help me out.
