SKR 2 32Bit Board + TFT35 E3 Screen + SKR TFT TMC2208 UART for SGEN CR10 Ender 3 V2 3D Printer Parts Compatible SKR V1.4 TMC2209 TMC2208 Upgrade BTT Turbo Driver
Product description：
The BIGTREETECH SKR 2 motherboard is a 32-bit 3D printer motherboard. It has added multiple functions based on the SKR1.4 and SKR1.4 Turbo series motherboards, which greatly protects the motherboard and is equipped with various types of expansion interfaces.
Features:
1. Compatible with Marlin and RepRapFirmware.
2. Fast heat dissipation, equipped with 3 PWM controllable fan interfaces.
3. Added TMC Diagjumpers, no need to cut pins in the absence of sensorless homing.
4. The device is simple, with on-board push-pull TF card slot (running in SDIO mode) and U disk interface.
5. Support 3 driving modes-SPI mode driven by TMC, normal STEP/DIR mode, UART mode driven by TMC.
6. Equipped with powerful main control chip, high work efficiency. ARM Cortex-M4 series STM32F407VGT6 main control chip, the core frequency can be as high as 168MHz.
7. Good safety performance, advanced thermistor protection circuit, thermal runaway circuit to increase protection, and Marlin integrated anti-reverse stepping driver protection design.
8. With dedicated WIFI interface, ESP8266 WIFI module (ESP12S or ESP-07) interface for customers to use RepRapFirmware.
Notice：
- WIFI module sold separately.
- After product update, send B version SKR 2 to test all motherboards
- If you use A4988 or DRV8825 driver, you must use jumpers to short-circuit RST and SLP to work normally.
