CH341A Mini Flash Programmer
Yaliyomo: [Vitu vya Dobrica PavlinuÅ¡iÄ visivyo na mpangilio maalum]
Hiki ni kifaa cha 5V bila marekebisho! Inanifanyia kazi (tm) lakini umeonywa http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Inua tu pini 28 na uweke mkanda chini yake ili kuzuia mzunguko wowote mfupi. Kisha solder waya moja kutoka kwa pini hii ili ubandike 2 ya AMS1117 na pia kwa C4. Upande wa C4 wa kuunganisha ni ule uliounganishwa kwa CH341A pini 9.

2-3 hali ya serial ya TTL
inayoungwa mkono nje ya kisanduku na flashrom, labda chaguo bora, lakini hata hivyo:

Niliongeza pinout ya soic 8 juu ya tundu la zif, kwa sababu nafasi ya pini 1 sio dhahiri (au imewekwa alama wazi mahali popote juu). Ninapendekeza urekebishe hiyo kwa ukali wa fedha.
