thankyou so much

I recently received a LCR-TC1 tester from AliExpress and it is the same blue board one with the LGT8F328 MCU shown on page 11 and replies #320 and #321.

If anyone is interested, I have reverse-engineered its schematic and have attached it here.

Could we have a robust link to that on AliExpress, since there are many sellers represented with different products?

I don't know that there is such a thing as a robust link to an AliExpress product as each time I have returned to the page of the item I ordered, it seems to have a different price! (it was about $14 when added it to my shopping cart, but I was charged $11.73 for it and it is now advertised as $9.57)

Anyway, the link to the page I ordered from seems to be:
 https://www.aliexpress.us/item/32611989538.html

That certainly works at the moment.

Bear in mind that price will depend on exchange rates, which will depend on multiple countries' whim.

I'd add that it's interesting that the photos on that page show that the cased variant has a USB connector for charging, while the uncased variant has a clip for a PP3 battery. It's almost as though they're intentionally preventing anybody swapping in the cheaper board when they blow the cased meter...
