BIGTREETECH SKR 2 Control Board for 3D Printer New Upgrade Silent Board Based on SKR V1.4 Turbo Motherboard for BIQU B1 Compitable TMC2209/2208, DRV8825 Support TFT Display, LCD, (with 5pcs TMC2209)

�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.
�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 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;
