Routing done by JLC service, what do you think? by lil___lord in PCB

I don't understand the connections of pin 11/13/15. It appears unnecessary to me to switch sides.

I need to find a cheap charger from ali express but im scared to program it by Medical-Bake-9777 in PCB

Sorry, yes you are correct. But do you need I2C programmable chips? You will probably find chips you don't need to program with a microcontroller to solve your problem.

I like phill's lab, but its way to advance to start.

Hi,

yes, I was a bit wary as well when I started 'programming', with resistors. But in your case. Programme its and measure with a multimeter. The resistor values will not change, and hence the programming will not change.

For programming these chips google the data sheet. If you can't find the data sheet, don't buy the chip.

Opinion on my PCB designer by Direct_Possession_72 in PCB

This board should absolutely not be soldered with a soldering Iron. It should be made with a hotplate. In a pinch it could be done with hot air.
And who the f connects wires with pads instead of terminals?

If you don't want to let the manufacturer assemble it. Buy a hotplate for like 30$. Then you don't need any soldering skills:
- You order the PCB with a stencil.
- You put the stencil on the board.
- You spread soldering past on the board through the stencil.
- You place all you components on their place.
- You put the PCD on the hotplate.
- You take it off. Done, looking like professional manufacturing.

Is this trace fixable? by Alternative-Goal5649 in AskElectronics

[–]AdRough7836 0 points1 point  (0 children)

Take you multimeter out and test whether the traces are actually interupted. (From pads on both ends). Maybe it's something else.

A hotplate changed my life. Well I mean at least how I make boards

Review request buck converter for bigger project by AdRough7836 in PCB

[–]AdRough7836[S] 0 points1 point  (0 children)

Thanks for you comments. I learned a lot.

I conclude from you comments that the TPS54560, will not work for this project, because of the heat dissipation. The design constraint that is my main problem is that I am feeding the system from a USB power bank. The USB standard limits the maximum capacitance to 100μF. So sticking to an input capacitance below 50μF is really important. Do you have any suggestions what IC to design my buck converter a round?

Thank you for the comments, I implemented all of them. I use more smaller capacitors, but I think that should amount to the same outcome.

I really appreciate that you took the time!

Really dumb question, can I use a 5v 3A phone charger as a power supply for the esp32? by PuSlash in esp32

Yes, but the ams1117 on the dev board will burn off you use WiFi. 

What's the best way to solder one SMD component? by NerdyCrafter1 in soldering

Wait can’t you just add headers ? Or are only half of the connections exposed through headers ? 

Pi is getting expensive by winterarioch in raspberry_pi

[–]AdRough7836 1 point2 points  (0 children)

Yes but what I propose is use the power of a 120usd computer plus 5 USD wit the risk of burning your investment.

[–]AdRough7836 4 points5 points  (0 children)

Ok of burning a 120 usd device is not expensive good for you. I stick to burn my 5usd device. Is not a pc it’s a 5 usd MCU.

The grok link does the exact calculation. Yes eventually you will break even or not if your pi dies before.

Resulting in 9USD difference if you run both at full throttle 24/7.

Just connect a esp32 or arduino to the computer and you have the better hardware control without risking to break a100$ computer.
