I was assigned to choose an existing project and design a custom PCB for it. My project involves LEDs arranged in a circle that light up sequentially, while the LED in the center is supposed to stay on continuously. After soldering everything together, the circuit didn’t work. When I measured...

I designed a 100 W synchronous boost converter that makes 12 V input voltage to 26.8 V output voltage with 250 KHz frequency for an MPPT application with a microcontroller. In LTspice simulation the circuit worked well but in the prototype it draws too much current than 6.5 Amps in every Duty...

I hope you are doing well. I'm a high school student and am in the process of designing a simple PCB through KiCad for a project I'm working on. This is my first time dipping my toes in any sort of electrical engineering so although the countless tutorials I watched helped me get started I'm a...

Hello I've been using breadboard for years . few weeks ago i found some nice deal on MT3608 ( a step-up switching ic) and want to use it in some project and so is the first pcb that i have made very sloppy following project is a part of another one i am not very sure how to rout switch node...

I have a model kit that comes with an LED kit and it has a 5 minute timer for the LEDs to stay on, then it'll turn off. I want to remove that timer so that the LEDs stay on indefinitely until i cut off the power or press the button to switch to a different lighting mode.

Hi guys, I am checking some online PCB designs for making my Raspberry HAT (figure 1). And I am confused with the wiring layout on female pin headers. I did vias (thru-hole) for connecting top with bottom layout like the figure 2. Given that I will weld the header on top layer for a HAT...

I have worked on basic low speed PCBs and understand basics of the design methodologies for it. But I am curious about the hi-speed PCBs like smartphone motherboards.. How are the components placed so close to make the PCB compact? How are the tracks routed in this tight spaces? What...

hello, I'm interested in designing a SBC, I would like to know your opinions and some links for examples or advices and steps for those that already did something similar ??
