Eusi: [Barang teu terstruktur acak Dobrica PavlinuÅ¡iÄ]
Ieu mangrupikeun alat 5V tanpa modifikasi! Ieu lumaku pikeun kuring (tm) tapi anjeun geus warned http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Angkat pin 28 sareng pasang pita di handapeunna pikeun nyegah sirkuit pondok. Lajeng solder hiji kawat ti pin ieu pin 2 of AMS1117 sarta ogé mun C4. Sisi C4 pikeun nyambungkeun nyaéta anu dihubungkeun sareng pin CH341A 9.
