I have little doubt, I have a KMOON FY6900 60mhz a month ago, and a good friend buys it for me at a price plus 10% that pays for more shipping costs, since I need it, and I think since I only use it for adruino and small electronic projects, with a Kmoon FY6900 20mhz, it reaches me and I am left with a few dollars in my favor, or should I keep the 60mhz one that is the only difference with that of 20mhz?
