From about 100-200 reviews for these cheap " aliexpress boards " so far I've found just one negative that's quality related and not shipping related ( FTDI chip was badly soldered ) - quite a low failure rate. These boards are very simple and their failure rate mostly depends on the failure rate of FTDI chips and their soldering quality > It writes just the same you get with cbmem -c utility, assuming you can reach OS on the DUT. Didn't know that, but its' too late ;) Best regards, Mike Banon On Mon, Mar 5, 2018 at 1:36 PM, Kyösti Mälkki <[email protected]> wrote: > On Mon, Mar 5, 2018 at 12:18 PM, Mike Banon <[email protected]> wrote: >> Hi Kyosti, Thank you very much for your reply! >> >> I will try to get a couple of these FT232H boards: perhaps just 1 is >> required for the successful setup, but these boards are not common >> (just 15 or 20 search results) so maybe its' a good idea to take 2 ;) >> > > Not likely those PCBs have gone through much testing on assembly line, > how about 4... > >> If this FT232H board works, it would be an ideal replacement both for >> commercial AMIDebug Rx / Ajays NET20DC (because much cheaper) and >> FX2LP (because no DIY will be required).
