There is a new product on the cheap serial programmers market. Nanjing Qinheng Microelectronics Co., Ltd. (the same company which created CH341A under the brand WinChipHead) released a new and improved USB interface IC: the CH347. Zigong Yaojie Electronic Technology Co., Ltd. used this chip to make an upgraded serial memory programmer. To be more specific, they used the “T” version (CH347T) for a cheap programmer in a similar shape and size to the well known CH341A Mini Programmer.
So, is it worth to switch to CH347T programmer? If you’ve previously used CH341A Mini Programmer you may know it had some voltage levels issues (not the IC itself, but the programmer by design). It’s time to analyze the new CH347T programmer to see if old issues were fixed and what new limitations come from its currently available version.
