Iki piranti 5V tanpa modifikasi! Iku bisa kanggo kula(tm) nanging sampeyan wis dielingake http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Angkat pin 28 lan pasang tape ing ngisor iki kanggo nyegah sirkuit cendhak. Banjur solder siji kabel saka pin iki kanggo pin 2 saka AMS1117 lan uga kanggo C4. Sisih C4 kanggo nyambung yaiku sing disambungake menyang pin CH341A 9.

jumper ing pin

1-2 SPI flash programmer mode
2-3 TTL mode serial
didhukung out-of-box dening flashrom, pilihan sing luwih apik, nanging uga:

Aku ditambahake soic 8 pinout liwat zif soket, amarga posisi pin 1 ora ketok (utawa cetha ditandhani ngendi wae ing ndhuwur). Aku suggest sing ndandani sing karo salaka sharpy.
