- The voltage of all 8 drives can be selected by the jumper, If the jumper is inserted on the left, the corresponding driver voltage is
MOTOR_POWER, it isMain Powerif it is inserted on the right. TheMOTOR_POWERport maximum voltage supported is up to 60V, theMain Powerport maximum voltage supported is only 28V. The all 8 drivers of this motherboard can be used in any combinationMOTOR_POWERorMain Power.
Warning: please make sure that the correct voltage is selected by the jumper In order to use the non high voltage version of the driver (such as: TMC2209, TMC2130, or Non high voltage version TMC5160), otherwise the driver will be burned, and even the motherboard may be burned.
- Support up to 60V high-voltage stepper drivers, and each driver can select the voltage from
MOTOR_POWERorMain Powerby jumper. - Both
NPNandPNPtype proximity switch are supported onProbeport(V1.0 / V1.1 can only supportedPNPtype). The IO of this port is no longer multiplexed with Bltouch, and a separate IOPC5is used for this port - On board
INA826is modified toMax31865, which supports PT100 / PT1000 and has higher accuracy. - The pin arrangement of raspberry pi header is modified to be exactly the same as raspberry pi. From top to bottom:
5V 5V GND RX TX.
- The IO of Octopus-Pro V1.0 and Octopus (non-pro) V1.0 / V1.1 are the same, except the IO of proximity switch
Probeport is no longer multiplexed with Bltouch and is modified to a separate IOPC5. Please refer to Octopus V1.0/V1.1 here - The IO of the Octopus-Pro V1.1 is different with the differences being shown in the table above.
