Hello guys, I need to turn on a small DC motor when a applied reference voltage is removed. Do you know a circuit diagram for this or any idea of doing this?
Why RC oscillators are used for generating below 1MHz frequencies, and LC oscillators for above 1MHz freqs? Why cant we use RC for high freqs, and LC for low-medium freqs?
The ACS712 outputs a voltage from 0-5V and the ESP32 ADC reads from 0 to 3.3V using 1.1V as vref. There is a voltage divider already to reduce the 5V to 3.3 range.The problem is: voltage drops on the ...
Hi all. The output frequency of this power supply is 20-100kHz. Since its DC out, which would be 0Hz, am I correct to assume that the 20-100kHz would be caused by the switching. So I could in theory u...
Can I connect a 0.5W Speaker direct to an input (Raspberry pi in my case) and expect it to be as loud as a let's say a phone speaker? Will a very small speaker work directly from an input? If not ...
Hi all, my mini USB connector somehow broke off the board and has been rattling around its casing, I opened it up and found where its supposed to be connected, is this saveable? could I just solder th...
Hello, I was wondering if it would be possible to have the Dimensity 1000 system on chip preinstalled to a pcb. I have not seen an option for it and I don't have the time to source the chips and s...
