The BIGTREETECH Stealthy Hi-Speed High-Voltage Combo Kit is a powerful all-in-one upgrade package centered around the Octopus Pro V1.1 control board. This bundle includes everything needed for a high-performance, quiet, and fast 3D printer build — especially optimized for Klipper firmware and Voron DIY printers.

Kit Includes:

1 × BTT Octopus Pro V1.1 Control Board with powerful STM32H723 chip
5 × TMC2209 Stepper Drivers (UART mode, excellent for silent operation and sensorless homing)
2 × TMC5160T Pro High-Voltage/High-Current Stepper Drivers (ideal for demanding axes requiring higher torque and speed)
1 × BTT Pi Core Board (for seamless Klipper host integration and RatOS/Voron compatibility)

Key Features:

High-Voltage & Hi-Speed Support: TMC5160T Pro drivers handle higher voltages for faster printing and stronger motors.
Ultra-Silent Operation: TMC2209 drivers deliver smooth, quiet motion with advanced stealthChop technology.
Klipper Optimized: Full compatibility with Klipper, input shaping, pressure advance, and sensorless homing.
Versatile & Expandable: 8+ driver slots on the Octopus Pro board, rich interfaces for fans, sensors, displays, and CAN Bus.
BTT Pi Integration: Enables direct high-performance Klipper host computing without extra single-board computers.

This combo deal is the ideal solution for builders upgrading to or building a new Voron series printer, high-speed CoreXY machines, or any custom Klipper setup. It provides professional-level performance with silent printing, high reliability, and excellent value compared to buying components separately.
