Hello everyone, Following the feedback I received in my previous thread(mentioned below), I’ve completed a full redesign of the board and would appreciate another review before moving forward with fabrication. The goal of this revision was not incremental fixes, but addressing the underlying...

Hi! I've made my own PCB layout, that I've etched my self. The circuit works on breadboard but once i made the PCB there are major fluctuations in the oscillation. I power it on and it oscillates at around 16kHz to then every now and then dip down to a more audible range but its very "jittery"...

I'm working on some boards that utilize the BME280 and AS7263 (separate boards). I just got them in yesterday from Osh Park, assembled them, and am now trying to experiment with them. Unfortunately, as of now, I haven't been able to get them to work when hooking them up to a Pi Pico. DRC...

Dear all, first, thanks for greating me in your community and sorry if I'm posting in the wrong section ! For a quick presentation, I'm from France, I'm 38, I'm an engineer in IT, mostly embedded safety SW for automotive. I've got some basics in electronics from school, but lost most of it in...

I've been working on a LED Chaser using 2 CR2032 batteries, a 4017 decade counter, and a 555 timer. Before I spend $50, I'd appreciate a review of my PCB to make sure I'm not losing my mind. Thank you!

Hello everyone, heres an quick overview of what the design does: the Si4703 radio tuner receives signals from the FM frequency band. Those signals will then get amplified by the PAM8008 module to output audio from the speakers. The current board stackup is sig/gnd/gnd/sig. Some additional...
