[QUOTE="Crankshaft, post: 481184, member: 941"] Found this info on the Chinese clones: The second version of rebuilded tester is build with SMD components. Also the x installed ATmega168 is a SMD type with 32TQFP body. Fortunately on the board is a 10-pole ISP connector provided for the programming. I have analysed the board version "2.1 2012/11/06". One error is the assembly of the part "D1", which should be a precision 2.5V voltage reference. Assembled is only a zener diode. This part should be removed. You can mount a LM4040AIZ2.5 or LT1004CZ-2.5 precision voltage reference at this place. A missing voltage reference is noticed by the software, so that you must not install the voltage reference. The last sentence is a bit confusing. [/QUOTE]
