Thermistor to ramps, schematics?

Hello!

I see these PCBs sold everywhere that you attach to ramps 1.3, but so far I have not found schematics of that little circuitboard, anybody know what other components are needed to attach thermistor to ramps?

Thermistor is 200k.

The question is not about the price, PCB costs about 1€, just that I forgot to order that PCB and shipping takes forever smiling smiley

Anybody with schema and component list?

Thank you!

You don't need any components, just connect the thermistor to the two pins on the board. And make sure to change the firmwares settings to use your 200k thermistor as 100K is standard.

That is for electronics without those components built in. Ramps has them right on the board making it easier and cheaper.
