NH3 question - what are W/Y/Z pt for?
NH3 question - what are W/Y/Z pt for? –
Looking for some expertise help! Pls refer to this diagram first:
First of all, is NH3 use 3.3V for it's Vcc?
I also found confuse to see that NH3 uses some pts that other chips need not. I see Magic3 has "W" pt as well but at different location. Also, old China Magic2 has "Y" pt as well (same location). What are "W" pt and "Y" pt for?
Anyone tried if D9 and AR2/GS2 works on it? Thank you very much!
