Ole masini 5V lea e aunoa ma se suiga! E aoga mo au(tm) ae ua lapataia oe http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Na'o le si'i i luga le pine 28 ma tu'u se lipine i lalo e puipuia ai so'o se ta'amilosaga pupuu. Ona faʻapipiʻi lea o le tasi uaea mai lenei pine i le pine 2 o le AMS1117 ma le C4. O le itu o le C4 e faʻafesoʻotaʻi o le tasi e fesoʻotaʻi ma CH341A pine 9.
