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 TMC2208)

OPEN BOX ITEM

💥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 TMC2208 stepper driver can combine actual micro-stepping and interpolation micro-stepping to achieve maximum torque. The firmware can dynamically switch the stepper motor between SteakthChop2 and SpreadCycle modes via UART. If the engine is not running, the engine standby power can be dynamically reduced.
💥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;

Motherboard features:
1. Uses a 32-bit ARM Cortex-M4 series STM32F407VGT6 main control chip with a core frequency of 168MHz that packs enough performance to run even the most demanding UI while ensuring stutter free printing.
2. 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;
3. Support all versions of the company\'s serial screen, SPI screen and LCD screen;
4. Upgrade the configuration firmware via SD card. This burning method is simple, convenient and efficient;
5. Supports functions such as power loss print resume, filament runout detection, shutdown after printing, BLtouch and other ABL sensors, RGB lights, etc. Note that external modules will be required for many of these functions;
6. Use high-performance MOSFET to reduce heat generation;
7. The use of replaceable fuses makes the replacement process more convenient;
8. Introduces a new “anti-reversal” 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;
9. ESP8266 WIFI module (ESP12S or ESP-07) interface for customers to use RRF firmware;
10. Onboard push-pull TF card slot (SDIO working mode) and U disk interface;
11. A filter circuit is added to the power input terminal to reduce ripple and noise interference;
12. 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;
13. The number of PWM controllable fan interfaces has been increased from one to three.
