SKR 2 motherboard is a 32-bit 3D printer motherboard , It is a
successor to the bigtreetech skr v1.3 SKR v1.4 and SKR v1.4 Turbo series of
motherboards and adds many features that we are sure the community will love.
ê¥More Features for SKR 2 32 bit 3d printer control board:
1. Introduces a new âanti-reversalâ stepper driver protection
which is achieved through a combination of new hardware and
Marlin firmware. This protects against motherboard or driver
damage due to incorrect driver insertion;
2. ESP8266 WIFI module (ESP12S or ESP-07) interface for customers to use RRF firmware;
3. Onboard push-pull TF card slot (SDIO working mode) and U disk interface;
4.A filter circuit is added to the power input terminal to reduce ripple and noise interference;
5.The fuses now use a smaller package which leaves more space on the PCB for more features and makes it easier to swap them out;
ê¥SKR 2 Parameters:
Input voltage: DC12V-DC24V,Logic voltage: DC 3.3V
Firmware support: Marlin, Reprap Firmware
WIFI interface: ESP-12S, ESP-07S
Fan interface: three CNC fans, two normally closed fans (non-controllable)
Motor drive interface: X, Y, Z (double Z axis), E0, E1, five channels (each channel has a closed loop drive interface)
The benefits of TMC2208 V3.0 UART mode:
1.Motor current can be set arbitrarily by firmware.
2.Micro-steps can be set arbitrarily by firmware (up to 256 actual micro-steps);
3.The actual and interpolated microsteps can be combined to achieve maximum torque.
4.Firmware can dynamically switch stepper motors between stealthChop2 and spreadCycle modes through UART.
