Hello, I have 3 ksger v2.1s stations and, I did tests for detect couterfakes ics on 2 of those stations on the "original" ic that came on the factory pcb, when doing the test to find out if it was fake it gave me the result 20036410, so I bought 3 ic from an Aliexpress seller and 2 from another AliExpress seller, because I imagined that some of the ones that would arrive would be fake, but oh surprise I soldered them all to the boards and I tested them and it showed the value 2003610, i do the test on 6 stm32 chips so i dont know if they are all fake, they are all original, or the counterfeiters have a way of writing this value in the IC, by the way I have already been testing the software in one of the soldering irons and I really liked it, thank you very much for your work.
