Review on KOOBOOK CH341A Programmer Adapter Converter by Jason Ballard

Revainrating 3 out of 5

Works, be warned this version has 5V output on the programming pins and 3.3V on the Vcc EEPROM pin.

Works but you need to modify the CH341 board IC to get power from the 3.3V regulator or it might damage the programmable IC. Look for "ch341a Programmer 3.3v fix" which is a common problem in earlier versions. The reason for this is that the chip is connected directly to the 5V USB input and not to the 3.3V regulator.

Pros
  • Good product for the price
Cons
  • weak
