BIGTREETECH SKR 2 Motherboard revision B 32Bit Board Upgrade for 3d Printer Machine

The BIGTREETECH SKR 2 motherboard revision B is a 32-bit 3D printer motherboard designed and manufactured by the 3D printing team of Shenzhen BIQU Technology Co., Ltd. It is a successor to the SKR1.4 and SKR1.4 Turbo series of motherboards and adds many features. Added multiple functions to greatly protect the motherboard, rich expansion interface.

Matters needing attention:

1. The jumper that allows selection between USB power or on-board power must be inserted so as to select one of the two options otherwise no power       will be supplied to the logic section of the motherboard and the power LED will not light up.
2. The power of the hot bed connected to the main board must be less than or equal to 10A. If you want to use a high-power hot bed, it is
     recommended to choose a hot bed with 24V power supply and use 24V to power the main board.
3. The jumpers that allow selection between SPI WiFi (for RRF) or U disk functionality should be inserted to select at least one option.
4.The driver anti-reversal insertion function is a newly developed function from BIGTREETECH. It is currently only supported in Marlin firmware
    and therefore not available when using RRF firmware. Therefore, when you are not using Marlin firmware, please carefully check whether the
    driver is inserted correctly to avoid causing damage to the driver and/or the motherboard. Customers can also choose to install the Marlin firmware
    first and then install the RRF firmware after they are confident that the hardware installation is correct.
5. This motherboard uses a push-pull type SD slot which does not eject when pushing on the card after insertion. The installation stroke is far shorter       than a push-push type
     SD slot and therefore customers should be gentle when inserting or removing a card. Returns for damage caused by mishandling the SD card will not be entertained.
