Spider V3.0 H7
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:
