• FYSETC-SPIDER-KING

  10 axis industrial grade 3D printer motherboard 1.1 Advantage 1. Replaceable control core: It has a replaceable control core(Named 'King' core).You can freely choose between 4xRP2040(King-R) / STM32F446(King-446) / STM32F407(King-407) / STM32H7XX(King-H7xx), and even you can make your own control core(We will open source the interface). 2. Intelligent identification of stepper driver type: With an additional MCU, Spider-King can identify the driver type and switch the SPI/UART channel automatically. This feature save you time on searching doc of how to set the jumppers, keep you away from borning setting jumppers. No longer has problems with stepper driver setting. (If you want to use this feature, you need our new stepper driver) 3.Few readers

• BIG-DIPPER

  BIG-DIPPER is a combination of Duet3 mini5+ and Mini 2+. It's based on ATSAME54P20A and pin assignments are exactly the same as those of mini5+, so the mini5+ firmware can be used directly. Compare to mini5+, the power supply and IO protection have been upgraded to a certain extent to make them safer. And you can switch between the WIFI version and the Ethernet version by replacing the module. WIFI version module supports external antennas. Based on the good ecology of the RRF firmware and on-board 7-axis (7xTMC2209), the board can be easily configured in a variety of 3D printer models, such as VORON series, multi-Z-axis models, double-X models etc. Compatible RepRapFirmware versions: RRF 3.2 and later For firmware update instructions, see Installing and updating firmware.Few readers

• STRIDEMAX_DUAL_FD_V2

  StrideMax Dual FD is a RP2040-based control board with dual TMC5160 drivers that can run RRF firmware or Klipper firmware. Each 5160 driver group has 8 high-power MOSFETs and is covered by a heat sink. It also provides two fan positions for expansion, so that the drive current of each channel can reach 10A, and it can easily drive an 86mm stepper motor. Two TMC5160s have a separate 12V power supply, which can greatly reduce power consumption and heat generation under high-voltage working conditions. StrideMax supports USB/CAN/CANFD multiple communication interfaces, and can be flexibly configured and used with RRF and Klipper firmware.
