SB CAN V2 is a newly designed SB tool board running Klipper firmware. Based on STM32F072, it provides two communication modes: CANBUS and USB. The onboard USBHUB has up to three USB interfaces, which can be used to connect to the scanning leveling sensor (Scanner Leveling Sensor,such as IDM or Cartographer )and AI camera, etc. It can also be connected vertically with an optional board for easy use.Few readersCatalyst.K ToolHead
Catalyst.K ToolHead is a compact Klipper toolboard with a footprint of only 47 mm × 44 mm, designed to be mounted close to the printhead or extruder. It is powered by an STM32G431CBT6 32‑bit MCU and supports multiple communication modes, including USB and CAN / RS‑232, which can be switched via an on‑board physical button. The board integrates a TMC2209 stepper motor driver, an ADXL345 3‑axis accelerometer, multiple fan and temperature inputs, as well as BL‑Touch and hotend heater control. This greatly simplifies toolhead wiring, reduces cable bundle weight on moving parts, and improves overall reliability and serviceability of the printer.Few readersSB Combo V2

UCAN is an open source USB-to-CAN interface board, based on the STM32F072 chip and candleLight open source firmware. It supports linux, windows, and mac. Of course, you can also develop your own firmware to use on it, as it is completely open source.Few readersM36_HUB_V1
The M36 hub board is specially designed for use with 36 circular stepper motors (Nema14) and can be used on mini Stealthburner or other print heads using 36 motors. This board can be used with a variety of motherboards, especially our catalyst and BullAnt. With special connection cables, it can also be adapted to any other system using klipper. M36 is divided into two versions, mainly because of the difference in motor driver chips. The normal version is TMC2209, used with Catalyst motherboard; the Lite version is GC6609, used with BullAnt motherboard.Few readersNanoDLP_Shield_V1.1.zh
