Hi all: are the t1,t2 terminals for a temp sensor? if so, what kind of sensor and what is the operational range.

There is no manual or any instruction about it, I googled similar boards and also Alibaba/Aliexpress. The only hit - its usually 10k thermistor (look for ntc 10k) and you have to remove smd jumper (0 Ohm) right near these terminals). I did not manage to find any documentation.

Does it come with the pigtail?

Yes, this item contained the pigtail.
