I got the TMC 2208 V3.0 which have 3 pins already soldered on top.


In the v3 manual at page 6, is mentioned that an 1k pull resistor must be also connected to the RX line thus D15 RX and D14 TX seems to be a good choice. Is this resistor needed, did you use it in your setup?

Second question is about pins: do I need to remove the 3 bottom pins and let only the UART top pins? Is it safe to let all the pins as they come from the manufacturer?
