3D printer motherboard SKR MINI v1.1 BIQU Bigtreetech

3D printer motherboard SKR MINI v1.1 BIQU Bigtreetech is a circuit that controls the operation of 3DP or CNC machines. The latest version of the board has been equipped with a 32-bit ARM class processor: Cortex-M3 with a frequency of 72MHz. It operates based on highly modular open source software - Smoothieware or Marlin 2.0.

The controller board has a dedicated power supply that supports 12-24V operation (when using 24V power supply, we can shorten the table heating time by about ¼, with the same power consumption).

Technical specification:

• Input voltage: DC12V-DC24V 5A-15A,
• Engine Controller: Supports TMC2130 SPI, TMC2208, also in UART and LV8729, ST820, DRV8825, A4988 etc.
• Motor drive interface: X, Y, Z, E0, 4 channel (each channel has an expandable interface up to 256 maximum),
• Temperature sensor interface: TH0, TB, 2 channels 100K NTC,
• Display support: 2004LCD, TFT35,
• Communication interface with a computer: square USB port,
• Supported file format: G-code,
• Machine construction support: XYZ, Delta, Kossel, Ultimaker, Corexy,
• Recommended software: Cura, Simplify3D, Pronterface, Repetier-host, Makerware.

Supported functions: resumption of work after power off, end of filament sensor, automatic shutdown and optional BL-Touch.
