very nice,
a question, the big one,
https://www.mouser.it/ProductDetail/...pw6a7XZQ%3D%3D
is it marked 220 uF is it correct or is this also from 22 uF?

[tkmmazda]

224 = 220 uH
220 = 22 uH

[elmer9]

224 = 220 uF
220 = 22 uF

number indicated on inductor 472
so is it wrong?
can you indicate the right one?
thank you

[tkmmazda]

What part is this marking on. I don't understand the question well. About 4,7 uH.
Where is this coil? The coils on China clones are good, it's useless to change.

on the photo for reworking components is indicated large inductor with code
MSS1260-224KLD

the value of the image is 472 and not 224, is it okay?

[tkmmazda]

But these are just illustrative images. The value is written in the description. Coil 220 uH has a marking of 224.

I looking the code parts of U13 , U15 and U17.
Have problem.with kess " Connection estabilished"
I changed Nxp (thinking is broken) .. i changed FDTI and programmed with correct data. Still the same problem. U13

how do you program ftdi?
where to find the files?
thank you

Program you can find On official fdti website, ftdi uttilities section

https://www.ftdichip.com/Support/Utilities.htm#MProg

MProg 3.5 - EEPROM Programming Utility
MProg 3.5 older program is replace now to FT Prog, but still both works.

FTDI KESS data
1. You can download/read ftdi data from exist working kess or try found on internet...

2. But i cant find from 5.017, so i found from kess 4.036, and pack name was someting like kess 4.036 sd-card content. They was sd image or content including ftdi firmware and mpprog.3.5, i can share both files later when i back home (evening)

But with my experience.
I have 2 kess clone 5.017 and both using 2 diffrent fdti data, configuration, so if some reason will dont work on one than need try to another.

need to unsolder CHIP FTDI? or you read with usb of the kess?
later he tried to read my ftdi, could you tell me the names of the integrated U13, U15, U16, U17 thanks

[pocinas]

No. No need desolder fdti. All you do soldered, the same with new chip, solder New chip and programm via usb.

All this elements is Cmos chips. But dont sure now the codes. Will tell you later and share dontent tonwrite ftdi

yes, share the file
with FT Prog I can't detect anything
I try with mprog
you have to explain to me how to proceed
1) USB cable connection to the kess
2) I open mprog 3.5
3) I click "Device" then "scan"
4) I click on "read" and "read and Parse"
5) then I click on "file" then "save"
it's correct?

yes see the same, FT PROG dont detect my FDTI chip, but MP PROG yes. (stange)

Yes how you said point 1-5 is all correct

look atachment there is 3 EPT files


P.S dont change the name files *.ept, from unknown me reason when i changed one files name than i can`t open in MP PRog, was some faults

The same if you like experiments with setting/configuration, this ept files only possible to change is open via notepad (can`t change settings in MT Prog program)

[pocinas]

later he tried to read my ftdi, could you tell me the names of the integrated U13, U15, U16, U17 thanks

U13, U15, U16 - CMOS Chips

U16 - MC74HCT125ADTG (package TSSOP 14) 100% is this
U13 - i think is 74HCT00PW (package TSSOP 14) iam not sure
U15 - i think is 74HCT02PW (package TSSOP 14) iam not sure

U17 - cFeon Qh16-104HIP (package SOIC8) SPI Serial Flash 100% is this

[elmer9]

this my 5.017 file
kess ftdi.rar

please write me the names of integrated codes U13, U15, U16, U17
