I’m running a printer with SKR 2 motherboard and an ODROID M1 as SBC to run Klipper. The SBC has Ubuntu installed. I brought a BIQU H2 500 extruder that came with a PT100 sensor. It also came with a MAX31865 board for reading accurate values from temperature sensor. However I do not have any spare driver slot to just slot it into. It needs to go into one of 5 slots on SKR 2 board which are all occupied by TMC2209 drivers.
What I need to know is that is there any way I can connect the MAX31865 board to ODROID M1 GPIO pins and then let the klipper read the hotend temperature from there and control the hotend?
Use above mentioned link from Sineos. I also use an SKR 2. Schematics and other infos are correct.
Attached schematics and pin diagram are from that link. I just added further information and changes on my SKR 2 (please don’t blame me, if I made a mistake ). BIGTREETECH SKR 2-SCH_hcet14_220619.pdf (173.9 KB) BIGTREETECH SKR 2-Pin_hcet14_220524.pdf (958.8 KB)
at first i wanted to connect max31865 to my odroid m1 board as there was no slot for max on my skr2 but now people have suggested to use exp2 slot on skr2 to connect max.
