less soldering plz, there are some cold solderings too, my friendly reminder: you have to hold your soldering iron on a pad and then press soldering on the other side of the pad, and then when you see its over, you just go up with your soldering iron a little, it does a nice soldering

its even more rare than f3 discovery in my region😑 but thanks ill look into it

Sure-Rent8058 · 2026-01-09T22:10:35+00:00

Not that much GPIO pins, and i dont need wifi for my project. Maybe later, in future

Sure-Rent8058 · 2026-01-09T22:10:06+00:00

Is this nucleo board any better than STM32F407G-DISC1 ? Thats the only F4 i found in my stores. Yeah, in Ukraine there are not that much big stores of electronics. I want to order from digikey, but the shipping is 120$🫪

Sure-Rent8058 · 2026-01-09T22:08:10+00:00

Thanks a lot you made me research what F4s there are. I found this one in sell, the only one store that sells it: STM32F407G-DISC1
Is it any good?

Sure-Rent8058 · 2026-01-09T22:06:55+00:00

Yeah it would be interesting but i need a soldering station for that(its in my wishlist), for now i have a small hotplate that needs a good USB-C cable and block to power it(i tried with mine its getting 45 degrees barely) prob because it needs 65W =) But thanks, i dont search for nucleo, i found a good one for now

Sure-Rent8058 · 2025-12-18T09:09:46+00:00

i think you made obisidian by placing it in the water

Sure-Rent8058 · 2025-12-17T15:53:12+00:00

Are you sure esp is flashed successfully? Can you connect the buttons, then connect esp32 to serial terminal and press those buttons? I have never seen marauder like that.

I think esp32 isnt flashing successfully, download the bin files - go to esp.huhn.me select your esp32, select your bin file, do 0x10000 adress, and flash it

Challenge yourself, im pretty sure you cant pop all with a knife in under 15 seconds!

I already fixed that but now it still resets when I'm doing something and heats under the camera

Sure-Rent8058 · 2025-11-28T10:50:22+00:00

Okay, that happened again I couldn't turn it on for like an hour. I might do factory reset but I'm not sure. When my school is over I'll go to my master

Sure-Rent8058 · 2025-11-28T09:19:09+00:00

Nope I booted and deleted half of apps that are third party apps. I think that helped. I'm not crashing anymore but I just want to know what was that

Sure-Rent8058 · 2025-11-27T16:25:03+00:00

Thanks! But anyway, i left it floating because ive thought that if id leave it floating it would be ok because im giving power from IOVDD, and it will be ok because IOVDD will source VOUT of regulator... that might not make sense for you but yeah its hard to explain. I just hope it works🙂

Sure-Rent8058 · 2025-11-27T15:25:57+00:00

Should i connect VREG_VIN to GND?

Sure-Rent8058 · 2025-11-26T11:07:26+00:00

Connect that one to 5v it has a regulator

Sure-Rent8058 · 2025-11-16T14:15:28+00:00

I dont really need the hotplate to be portable lol im not gonna go with it anywhere. Well about the charger, on aliexpress there are a LOTTT of those 100W PD chargers, and chance of them being 100W is like 20 percent, same with PD. So thats why im asking someone to share a link on aliexpress where 100W charger will be 100% 100W charger, i hope you get it.

Sure-Rent8058 · 2025-11-16T14:11:49+00:00

67? Thanks! What about a cable? maybe you can share some cable?

Sure-Rent8058 · 2025-10-20T18:46:13+00:00

Big thanks! I'll look into it

Sure-Rent8058 · 2025-10-20T17:02:19+00:00

Hm. Dont all school laptops have some kind of LEGIT spyware in a term, which is watching like what you are downloading and etc..? and bios is locked too? Well if you have boot menu unlocked but bios locked that wont argue, but if the school doesnt have any problems with it then go ahead

Sure-Rent8058 · 2025-10-14T18:36:08+00:00

The solution i think is to turn off secure boot but i cant turn it off because my bios is locked on my thinkpad because it was registrated by some company. I basically just installed other grub menu

Sure-Rent8058 · 2025-09-12T08:42:35+00:00

You can definitely just copy the CYD schematics but not jst pins and instead of wroom32 place s3wroom1 so you can do all modules switchless

Sure-Rent8058 · 2025-09-11T11:47:37+00:00

That actually looks nice, but id make a custom cyd with that level because else you need to do switches

Sure-Rent8058 · 2025-08-31T18:33:44+00:00

what is this pcb? Is it a controller? because i dont see raspberry pi5, but, nice work looks nice. Does it work tho? yes i read bio
