CH341A Mini Flash Programr
Clàr-innse: [stuth neo-structaraichte air thuaiream Dobrica PavlinuÅ¡iÄ]
Is e seo inneal 5V gun atharrachadh! Bidh e ag obair dhòmhsa (tm) ach chaidh rabhadh a thoirt dhut http://www.eevblog.com/forum/repair/ch341a-serial-memory-programmer-power-supply-fix/Dìreach tog prìne 28 agus cuir beagan teip fodha gus casg a chuir air cuairt ghoirid. An uairsin cuir aon uèir bhon phrìne seo gu prìne 2 de AMS1117 agus cuideachd gu C4. Is e taobh an C4 airson ceangal am fear a tha ceangailte ri prìne CH341A 9.

Chuir mi soic 8 pinout thairis air zif socket, oir chan eil suidheachadh prìne 1 follaiseach (no air a chomharrachadh gu soilleir an àite sam bith air a’ mhullach). Tha mi a’ moladh dhut sin a chàradh le cèir airgid.
