BIGTREETECH SKR 2 Main board features:1. The ARM-level Cortex-M4 series STM32F429VGT6 main control chip with a 32-bit frequency of 180MHz is adopted, and the performance is greatly improved.2. Support all versions of the company’s serial screen, SPI screen and LCD screen: TFT35 E3 V3.0 , TFT35 V3.0 , TFT43 50 70 display , TFT24 , 12864LCD , MINI12864. Support drive: SPI, UART, STEP/DIR. TMC2209 TMC2208 TMC5160 TMC2226 TMC2130, ST820, LV8729, DRV8825, A4988, etc.3. Increase the protection circuit of the thermistor part to avoid the burning of the main control chip caused by the leakage of the hot bed or heating rod. 4. Increase the heating rod MOS tube protection circuit, when the main control chip is damaged or the heating rod MOS tube is damaged, the power supply of the heating rod can be cut off in time to avoid the risk of fire.5. Supports functions such as continuous printing after power failure, filament interruption detection, shutdown after printing, BLtouch (When using BL TOUCH, pay attention to the wiring sequence) and RGB lights, etc.6. A filter circuit is added to the power input terminal to reduce ripple and noise interference.7. Upgrade configuration firmware via SD card. 8. Use high-performance MOSFET to reduce heat generation.9. Use replaceable fuse, the replacement process is more convenient.10. Onboard not pop up automatically TF card slot (SDIO working mode) and U disk interface. The board does not provide SD cards. Because the SD card will damage the slot during the delivery process, you can better protect the motherboard by using your own SD cardmeters:Appearance size: 110*85mm. Installation size: 102*76mmInput voltage: DC12V-DC24V. Logic voltage: DC 3.3VFirmware support: Marlin, Reprap FirmwareWIFI interface: ESP-12S, ESP-07SFan interface: 3 CNC fans, 2 normally open fans

- 1.【SKR 2 Control Board】 Adopt power chip AOZ1284PI, support 12-24V power input, output current peak value 4A. The instruction manual and firmware: github/bigtreetech/SKR-2
- 2.【Protection Circuit on Thermistor Inputs】Increase the protection circuit of the thermistor part to avoid the burning of the main control chip caused by the leakage of the hot bed or heating rod.
- 3.【Heater Protection Circuit】Increase the heating rod MOS tube protection circuit, when the main control chip is damaged or the heating rod MOS tube is damaged, the power supply of the heating rod can be cut off in time to avoid the risk of fire.
- 4.【Use the Driver】The SPI working mode and UART working mode driven by the onboard TMC, the DIAG function pin on the board, can be used by simply pulling and inserting the jumper cap. Increase the driver’s anti-reversal insertion function (Marlin firmware) to avoid the occurrence of the event that the motherboard is burned due to the driver’s reverse insertion.
- 5.【TMC2208 UART Driver Benefits】Motor current can be set arbitrarily through firmware; The micro-steps can be set arbitrarily through the firmware (up to 256 actual micro-steps); It is possible to combine actual and interpolated microsteps to achieve maximum torque; The firmware can dynamically switch the stepper motor between stealthChop2 and spreadCycle mode via UART; When the motor is not moving, the standby current of the motor can be dynamically reduced.
