32Bit Higher Performance MicroprocessorSKR 2 silent Main board adopts 32 bit ARM level Cortex-M4 series STM32F429VGT6,180MHz frequency microprocessor, which totally a new upgrade Motherboard of SKR V1.4 TurboSKR V1.4.. On-Board SPI and UART mode of TMC driver SKR 2 controller baord on-board TMC-driver SPI working mode and UART working mode, the on-board homeless sensor function,then SKR 2 can be used by simply pull and insert the jumper.. Multiple FunctionSKR 2 Support resume printing while power of,filament break detection and automatic shutdown after printing function.In the meanwhile,it can support serial screen, SPI screen and LCD screen like TFT2.4TFT70TFT3.5 inch colorful display and 2004LCD12864LCD.. Thermal runaway protectionWhen the main control chip is damaged or the MOS tube of heater is out of control, then it will be effectively to cut off the power supply of the heater in time.. Firmware Update Our SKR 2 board comes without SD card, then please use your own SD card to download firmware of motherboard through our GitHub website in the third picture, copy and save it to SD card. firmware must be reserved ,then re-plug the SD card and wait to 10s.The firmware has been successfully updated when the progress bar and interface appear..

Integrates a AOZ1284PI power regulator which supports 12-24V power input and a maximum output current of 4A enough to power external components such as LEDs and even a raspberry pi. TMC Motor drivers can be used in SPI or UART mode by simply adjusting the onboard jumpers beneath each motor driver. Additionally you can connect or disconnect the TMC DIAG pin using an onboard jumper allowing you to use hard endstops or sensorless homing without the need to cut any pins.. Includes a protection circuit on thermistor inputs which protects against short circuits between the heater cartridge and the bed heating element. This is a common mistake made by many users when replacing a nozzle or working on the hotend so we expect this feature to be a welcome one. Includes an additional heater protection circuit which protects against runaway heating on the bed and hotend heaters. By default, the heaters are off so if the MCU or MOSFETs are damaged, the heaters will shut down instead of enter into thermal runaway. If you have any questions, you can contact us via Amazon. We will help you to solve the problem which you meet. Thanks for your support and understanding..

Main Control Chip FeaturesThis new SKR Mini E3 V2.0 motherboard uses the STM32F103RET6 main control chip, and its flash memory size is 512K.. CNC FanBecause the fan on the SKR Mini E3 V2.0 control board is a CNC fan, you need to set the wind speed before using it. Note V2.0 version of the fan is not ready to use after power on.. Hot-bed MosfetThe hot bed MOS tube uses WSK220N04, low on-resistance, larger heat dissipation area, and reduce heat generation.. Upgrade FeaturesSupport BLtouch, filament detection, power-off resume, automatic shutdown, etc . Increase the distance between the driving chip and the components to avoid the trouble caused by the heat sink. After-sales SupportIf you encounter any problems, please write us via Amazon as soon as possible. We have professional technical after-sales personnel to solve your problems.

The main control uses the ARM-level Cortex-M4 series with a 32-bit dominant frequency of 168 MHz STM32F407ZGT6 chip, performance is greatly improved..

Reserve extended ports of BL Touch, PWM, ADC, UART, I2C and SPISupport power-off continuous printing, material cut detection, shutdown and other functionsSupport for dual Z axis printers series dual Z..

About MCU, If you received the main control chip about STM32F429VGT6 Before DIY firmware modification, customers need to build an F429 environment on the compilation platform for compilation and use, instead of directly using the previous F407 firmware. For more details, please refer to the tutorial on Github or you can write to us.. Integrates a AOZ1284PI power regulator which supports 12-24V power input and a maximum output current of 4A - enough to power external components such as LEDs and even a raspberry pi. Includes a protection circuit on thermistor inputs which protects against short circuits between the heater cartridge and the bed heating element. This is a common mistake made by many users when replacing a nozzle or working on the hotend so we expect this feature to be a welcome one. The TMC2209 stepper driver is not easy to lose steps and is in an ultra-quiet mode the module has a large area of heat dissipation pad, which can reduce the temperature of the driver when it is working the module supports three modes STEP DIR and UART.. Includes an additional heater protection circuit which protects against runaway heating on the bed and hotend heaters. By default, the heaters are off so if the MCU or MOSFETs are damaged, the heaters will shut down instead of enter into thermal runaway.
