Right now from my experience, it seems the best option is to get the self build kit, that way you can be sure of getting a component tester you can easily self repair, mod and upgrade the firmware.

I am confused, board gives power only on pins 18(gnd) and 19(vcc), but datasheet say pins 3 and 4! I think the chip has wrong markings on it, probably on purpose. there is also no oscillator on board.
What kind of chip this could be? Atmega3208 maybe?
I'd recommend to use precision sockets. Cheap ones tend to cause connection problems after a while, especially when the ZIF is a bit wiggly (no tight fit allows movement of the ZIF).
Very disappointing, the mega328 was almost 1/4 the price of the tc1 tester and now not getting it to work any time soon!
I get it there is no firmware available for it yet, or the chip not available to buy!
Clone tester with a clone chip from a clone!
Hope the mega328pb is still ok, to keep for the t4, just in case another charged cap comes around!
There seems to be a ~US$5 price difference between the LCR-TC1 and LCR-TC2 on Aliexpress. I'm guessing that covers the price of a real Atmel chip
I just received a LCR-TC2 from China...
I just received a LCR-TC2 from China... I didn't like the first test, short-circuiting the three pins didn't launch the calibration, it directly measures the short-circuit resistance, from what I've read in this thread this may be because the resistors are out of spec Seeing the board, my fears have come true...
Delivered my T7 with a clone Mega328, pcb similar to LCR-TC1(2) from the file TableClonesEN.pdf by indman@EEVblog

Let's say we received a new Chinese T7 clone, a TQFP32 MCU without any marks @16MHz. Is there any way to make an educated guess on what knock-off it can be, LGT8F328P or other?
