If you plan to use a voltage higher than 24V on MOTOR_POWER_IN then please pay attention to the following footnotes on the "Color PIN Diagram": 1.
You may need to change the Fuse on the MB_POWER_IN, calculate the maximum amps you will be using (3.(the four heaters {HE0-HE3}, 3.3V rail, 5V rail, and 12V rail all come off the 24V rail). The maximum amps for 3.3 V rail is 1 Amp. The maximum amps for the 5V rail is 8 Amps. The maximum amps for 12 VDC rail is 4 Amps. So the total maximum amps for 3.3 VDC rail + 5 VDC rail + 12 VDC rail is equal to 13 Amps, but the amps needed to run the four heaters needs to be added to this value. Since BIGTREETECH supplies us with a 20 Amp fuse, then BIGTREETECH is saying that you have 7 more Amps available for the four heater ports or 1.75 Amps / heater cartridge.
