CH341A Mini Flash Programmer
Cov ntsiab lus: [Dobrica PavlinuÅ¡iÄ's random unstructured khoom]
Qhov no yog 5V ntaus ntawv tsis muaj kev hloov kho! Nws ua haujlwm rau kuv (tm) tab sis koj tau ceeb toom http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Tsuas yog nqa tus pin 28 thiab muab qee daim kab xev rau hauv qab kom tsis txhob muaj qhov luv luv. Tom qab ntawd solder ib tug hlau los ntawm tus pin no mus rau tus pin 2 ntawm AMS1117 thiab kuj mus rau C4. Sab ntawm C4 txuas yog ib qho txuas nrog CH341A tus pin 9.

kev txhawb nqa tawm ntawm lub thawv los ntawm flashrom, tej zaum yuav zoo dua kev xaiv, tab sis txawm li cas los xij:

Kuv ntxiv soic 8 pinout dhau zif lub qhov (socket), vim tias txoj hauj lwm ntawm tus pin 1 tsis pom tseeb (lossis pom meej meej nyob qhov twg ntawm sab saum toj). Kuv xav kom koj kho qhov ntawd nrog nyiaj sharpy.
