Compare the features of ZEDFREE, ZEDPRO and ZED! in order to download the version that best meets your needs.
Attach your CH341A programmer to a PC. Use the SOIC8 clip to connect pins 1-8 to the EEPROM in-circuit (you don't need to desolder). Open AsProgrammer or NeoProgrammer .
The HEX V2 clone case is plastic with no screws—gently pry along the seam with a guitar pick or spudger.
: Female-to-Female jumper wires to connect the programmer to the interface board.
Look for an 8-pin SOIC chip labeled 24C02, 24C04, 24C08, or 24C16 . It is usually near the main ATmega chip. vcds 2231 hex v2 clone repair work
Launch your VCDS software, navigate to , and click Test .
