1. Introduction

Spider V3.0 H7

The Fysetc Spider V3.0 H7 is a high-end 3D printer controller board aimed primarily at custom printers such as Voron builds, CoreXY machines, and heavily modified printers running Klipper. It's essentially an upgraded version of the earlier Spider V3.0 F446, with a much faster MCU and improved high-voltage motor support.

Features vs F446 version

STM32H723VGT6 @ 550Mhz
Independent Motor Power input, 60V Peak (removed one MOSFET ouptut)
Voltage Selector on every Driver
120uF/63V Capacitor for Motor Driver
DotStar RGB Support

3.3 Wiring

3.3.1 CAN

There is a permanent 120 ohm termination resistor soldered to the board, no need to add a jumper to enable it and also no ability to disable it.

The CAN port on the Spider V3.0 H7 is a 3 pin JST-XH header located here:

DFU mode

To put the Spider V3.0 H7 into DFU mode, hold the BT0 button and while still holding press and release the RST button. Then count to 5 and release the BT0 button.
