Subject: Seeking Guidance on ATM90 IC for Energy Metering
Hello fellow electronics enthusiasts,
I hope you're all doing well. I'm reaching out to this wonderful community in the hopes of gaining some insights into a specific area of interest. My name is Ammar Waseem, and I'm an electrical...
I have a design for a SSD1306 display driver below that I tested last night and worked (given the I2C address sometimes changed out of nowhere and every couple hundred frames would have artefacts), however this morning the display is no longer even being detected by an I2C bus scan.
I am doing a double pulse test of MOSFET (PN: IAUS300N08S5N012TATMA1). Since we have high voltage spikes and oscillation of Vds in hardware testing, I am also working on LTSpice of double pulse test. I am so confused about the parasitic parameter of the MOSFET lib, I know the MOSFET has...
As the title states this is my first PCB I have designed purely through documentation, I have this designed through breadboards and breakouts but am attempting to put it all onto a single board so I can scale it down after I know it all works. Are there any people I can talk to to fix design...
I was asked to help in reviewing an already done PCB for a product in my company.
What are the aspects I should keep in mind when reviewing a PCB or when editing this PCB?
For example, I know there has to be a review for availability of the ICs as there is a shortage right now.
Iam looking at trying out a Flex rigid design to save some component cost,etc my current design has 5 ribbon cables running from a main pcb to sub pcbs.I can only find flex rigid designs that have the flexible pcb start at a edge of the rigid pcb, my question is could i have the flexible pcb...
I am designing a power supply board from a 72V battery pack using LT3958 (datasheet here) in SEPIC configuration. For SW node and GND connections, I used a copper pour without any thermals. This was because, when I used thermals the pour was not surrounding the pads. Is it safe...
New to PCB Design and layout. While routing bypass caps, I instinctively give each bypass cap its own via to the ground plane. What would be the disadvantages of having two (or more) bypass caps share the same ground via?
I suspect the consequences are more apparent in high-speed and/or high...
I am looking for any advice on my first PCB design. The function of the board is to monitor a battery pack and send the data to a smartphone via BLE.
It also includes a power supply for Arduino and other sensors. I am using LT3958 in the SEPIC configuration for this. I used...
I have a first draft of a 24VIN 200VOUT PCB and I would appreciate any feedback and suggestions, especially from anyone who has experience with switching power supply design. This is a two-layer board with a ground plane on the bottom layer.
Some things that I considered while laying out...
Could anyone provide me the knowledge on how to design the pads for this connector with special mark on point 7.
How to handle the Shaded region in this design.
1. Is that need to be considered as a pad? (or)
2. Shaded region is no need to consider as a part in footprint? (or)
3. Shaded part is...
Hi. My friend Conradie makes a new idea about the morning mix machine.
In historical times, before the pandemic, most people had to commute to work in the mornings, and breakfast often ended up being a bit rushed. [Elite Worm] is very serious about getting his breakfast mix exactly right, and o...
I am using TE Connectivity Right Angle 50Ω PCB Mount Fitting BNC Connector for signal output in a PCB Board.
It contains 2 Pins. Is Pin 1 for Signal and Pin 2 for ground?
Also, do I need to add any protectors(EMC, Etc...) inboard for this.
Thanks in advance
I am designing and developing a low voltage Battery management system . i have designed whole circuit but in one small thing i am stuck. kindly help me answering it.
Battery Pack specifications:
36 V 2.5 AH 10s battery pack.
maximum voltage : 42 v
Minimum voltage : 30v
I'm currently designing my first Pcb and I don't know how to stack-up the layers. I
The following list shows the components i'm using in my design:
Arduino : +5v
Ad9833 module: +5V
Amplifier : ±Vcc or ±5V
Multiplier (Ad633) : ±Vcc (Vcc > 8V)
Switched Capacitor Filter (Max293) : ±5V...
I think I've done everything I can to make my PCB as quiet as possible... I hope. Note that there is a switch mode power supply on the board but far away. Any suggestions/tips for how I can improve the layout? There is nothing on layer 4 bottom in this area. The ADC is measuring a load cell...
I have always used Eagle for my designs because it is free, well supported and nice UI. Recently I received a design in Kidcad which I tried to export to Eagle but I was unable to do so. Then I thought, hey! why not using Altium, because I see that most of the job offers for Hardware design as...
I need a clarification that i have designed a PCB board which has 4 layers, and no components has only holes with supply and ground.
My board has failed in dielectric test.
1) How much time i can test my board for dielectric test.(1,2,times..infinity??)
2) my conductors are so close...
