BIGTREETECH Octopus V1.1

Remove all the jumpers on the board before starting. Insert the jumpers onto the highlighted pins.

UART mode - placing these jumpers will allow for tuning and controlling options on the printer interface.

USB-C Power option - with this jumper the board can be powered via USB-C. This will allow you to compile and download the firmware directly to the motherboard using DFU mode, ideal for testing the board.

Voltage Selection - Each fan output can be set to one of three different voltages (5V, 12V or 24V) depending on the jumper positions. The third image exemplifies where the pins must be placed to achieve different voltages.

The voltage selections used in the guide are for the electronics kit provided by Rat Rig. If using different fans, ensure the voltages are set correctly to avoid damage to components.
