The Spider V2.3 board is a full-featured and excellent controller board, with space for EIGHT TMC stepper drivers, the ability to connect a Raspberry Pi directly to the board either through USB or through UART. Recommended for Voron 3D Printers and others. 

This board has add-on options, please review prior to purchase.

Please see note at end of description for important information about this board!


  1. Change 12v-24v RGB port layout to 3 fan ports, which can be used as a fan port more conveniently and still maintain RGB output support
  2. Optimize the fan control circuit, upgrade the buffer chip to independent triode control, enhance stability and greatly improve safety performance
  3. All motor drive module interface communication networks add high voltage buffering and voltage clamping processing, adding a shield to the MCU
  4. Re-layout the PCB, connectors position changed
