Change the Raspberry Pi 5V (3A to 5A) and system 5V(5A to 3A ).Change the series diode of the driver circuit to a 15A fuse（1808）.Change the Raspberry Pi 5V and system 5V to separate DC-DC circuits (3A per channel).Add TVS and Bleeding resistance to every stepstick socket.

It is USB power-supply port without USB signal. You can solder the below USB port, then you can power-up RPI with a USB-A cable. Switch EXP1 & EXP2 mark(Only mark, not socket)Īdd room for RaspberryPI USB-A power supply port.If you are building VORON, this will be your best choice. Especially for VORON V2.4, we cooperated with the VORON team in the early stage of design, and many features have been recognized by the VORON team. You can build a 3D printer with rich functions through SPIDER. In a limited space, it integrates 8 stepper motor drives, 5A 12V power supply, 8A 5V power supply, which provides powerful energy for fans of various voltages, various RGB light strips and Raspberry Pi.

SPIDER is a small but powerful 3D printer control board.
