I actually have a CHA341a Black version here, but its the 3.3v version (which I modded to be actually 3.3v not 5v on the data signals). However while it can read my 1.8v Winbond BIOS chip, its not successfully Writing to it. Which is most frustrating.

I have ordered the 1.8v version from Amazon but would really like one here, right now for reasons. Anyone got one to sell or loan?

thanks

What chip are you trying to write? Form factor, model, number of pins etc,
In Auckland I might be able to help, I.e. Write it myself for you...
P.S. My various programmers are not for sharing.

Hi, I'm in Wellington however it's a Winbond 25q80ew.
I've just rigged up my 3.3v CH341A to a pot and set voltage to 1.87v and no change, says its successfully flashed, but it's not.
