Choosing programmer

[valerio_vanni]

I come from this thread (I have to flash a SOIC-8 chip, possibly with a clamp).
I began searching for a CH341A, since it has low price and it's an operation that is not going to be frequent.

But during my search I discovered that there's often an issue with voltage, that is 5V instead of 3.3. Someone says to look at PCB colors, some other that it doesn't matter.
I see that someone has fixed the programmer, but as I said in the original thread I'm not good at soldering / desoldering activities.

CH341A cost down to 2-3 euros. It seems inviting, but I don't need to spend so little, I'd prefer to spend 20-30 (or something more) and having something that works out of the box.
What could I search for?

Programmer XGecu T48

Thank you. I found this on aliexpress, does it seem good, bad, fake etc?

And as software, what could I use with that programmer?
These ones I find here?

+1 fot T48, don't get the full kit with extra adapters (that you may not need), instead get the adapters you need separately
Another consideration is when using a clip with the T48, you have to lower the SPI clock frequency to 4-8MHz otherwise you will have reading errors
If using a clip, it will also tell you if the chip is connected properly, or which pin is not making connection, useful when using a clip

This one comes with some extra adapters, including a SOIC8 clip

I'm still waiting for the T48 I ordered 11 days ago: https://it.aliexpress.com/item/1005004419364127.html
But, in the meantime, I received an EZP2023+ I had ordered some days before.

Should I wait the other or try with this one?
I gave a look to it with multimeter, and there is no voltage above 3.3 V.

Your SPI GD25B64CSIG (3.3v), if supported by your programmer, you can try it, observing the pinout.

Programmer is like this:

About pinout:

In the picture I can see two boxes 4+4. The notch should point pin1, but correct box is the one near to lever or the on far from it?
When I see pictures of CH341A, there is a picture "25 chips in this box, 24 in this other". Here I read 24/25/93/95. But where?

About software: in bundle with programmer I find an EZP2023+.exe, a config file and a chip list one.
In that list I don't find my chip. The best matched string is "GD25". Perhaps it could auto-detect?

I don't own EZP2023+, only the T48 and CH341A (green PCB), from a YT video looks like pin 1 is close to the lever (top position)



From the software found here https://www.badcaps.net/forum/troubl...drivers-needed
GD25B64 is not listed, but there's GD25Q64, select Type SPI_FLASH, Manufacturer GIGADEVICE, Name GD25Q64 which should be compatible
If using a clip, lower the speed to 6MHz or 3MHz to try to get a good read, make sure the backup is not full of 00 00 00 or FF FF FF. read the chip 3 times and compare the backups with hex editor, should be identical
