Zviri mukati: [Dobrica PavlinuÅ¡iÄ's random unstructured zvinhu]
Ichi chishandiso che5V chisina kugadziridzwa! Zvinondiitira (tm) asi wanyeverwa http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Ingosimudza pini 28 woisa imwe tepi pasi payo kudzivirira chero pfupi pfupi. Wobva watengesa waya imwe kubva papini iyi kuenda pini 2 yeAMS1117 uye zvakare kuC4. Divi reC4 rekubatanidza ndiro rakabatana neCH341A pini 9.
