Hello everyone. I was wondering does this board (phot below) actually can programm KB9012 chips with the mini programmer CH341A? If yes how?

Re: KB9012 programming
I actually found a programmer called Ene programmer which costs 90€.
Maybe I’ll buy it when I have the expenses.
I liked it.Comment

Re: KB9012 programming
Personally have not worked these devices nor the related tools..yet but I think there are less expensive tool kits that should work fine for your programming on the following landing page:

Re: KB9012 programming
Well, the difference is 20-45€. But thanks anyway.
But I still didn’t understand the purpose of the above PcB.Comment

I'm able to read and write the chip by selecting a winbond IC of the same size, but when verifying it fails at around 25 percent.
I've modded the ch341a to 3.3v.
Can I update the database to include the XMC 25QH256C? -
zz0.8tpitu4y0i8zzI bought a ch341a (I'm waiting for it to arrive) and I noticed that the programmer has a bug that the data pins go to 5v when the VCC pin is at 3.3v (which is the voltage I'm looking for).
Instead of doing the 3.3v mod, I'm thinking of converting the 5v to 3.3v with an 8 channel TXS0108E through the ZIF socket but I don't know if that would work, because it has to circulate voltage and also information.
What I am looking for is something that will convert from 5v to 3.3v but without modifying the ch341a.
I can't buy the ch341a 1.6v that has... -
Hello folks,
(First post of mine, after introduction).
I came here to seek help for a board SPI reprogramming.
The referred board belongs to an Archer C9 V.4 EU router, which I believe, is bricked, (I was the one to brick it during a flashing operation with custom dd-wrt firmware upgrade).
The IC that I want to flash is this one:
Datasheet for the IC in question .
The one in the motherboard has 16 pins. (There are other IC in the motherboard, with 8 pins each, but I am almost positive that the one that will... -
Dear friends, I want to share my experience repairing an ASUS TUF FX506L gaming laptop motherboard: DABKXDMB8E0_F_BKXD. Boardview and schematic are available, as well as the BIOS and ITE ROM.
When the customer brought in this laptop, it was initially dead; it showed no signs of booting for any reason. After hours of measurements, checking each stage, MOSFET, and seeing if there was a short circuit in any capacitor, I discovered a strange 0.7V leakage voltage on the 3V_S5 rail, particularly on the PL9 coil, with the board not powered on. There were 3V_LDO and 5V_LDO voltages, which... -
Hello,
I'm desperately trying to get my CH341A to work, but it seems that all my attempts have failed. Despite everything, I want to check that it works, the aim being to read at least one chip and “screenshot” the configuration for me to use as a reference.
Here are the steps (software part):
- I'm running Windows 11 Pro 64-bit (10.0 build 26100)
- Drivers are installed (no error messages) and there are no problems in the Device Manager.
- Set the language to English (to avoid the CH341A's basic software bug)
- Does not work on AsProgrammer...
