Fysetc Spider 446 V2.3 3D Printer Controller Board

Now Supporting up to 60V Drivers!

V2.3 Change Log

Change 12v-24v RGB port layout to 3 fan ports, which can be used as a fan port more conveniently and still maintain RGB output support

Optimize the fan control circuit, upgrade the buffer chip to independent triode control, enhance stability and greatly improve safety performance

All motor drive module interface communication networks add high voltage buffering and voltage clamping processing, adding a shield to the MCU

Re-layout the PCB, connectors position changed

Features:

• Compact size: 155.3mm x 76.5mm

• Based on STM32F446 180Mhz，all IOs can withstand 5V voltage

• 8 TMC stepper drivers support, with Uart&SPI support

• Improved TMC jumper settings again，simpler and easier

• 28V input max，12V@5A DC-DC，5V@8A DC-DC (Especially for Raspberry Pi)，3.3V@0.8A LDO

• Two car fuses for hot bed input and main power input

• Limit switch socket 24V/5V/3.3V optional, ready for more other equipment, such as -inductive sensor, BL-Touch

• XH2.54 connectors

• 10x PWM capable power mosfet outputs (1 for HotBed, 3 for Heat-End, 3 for fans, 3 for RGB LED strip)

• 3pin temperature header, you can use thermistor or thermocouple (requires AD597 module)

• Up to 8 ways PWM fans (only use 1 extrueder and no 12V/24V RGB used )，2 ways RGB led(12V & 24V optional) ，1 way 5V-RGB led (NEO-PIXEL/WS2812)

• RepRapDiscount SmartController compatible pin header on board

• UART1-Raspberry Pi pin header (including 5V@8A power supply)

• 2X4 PinHeader Out for SD Card moudle

• Onboard micro-SD card

• Type-C and Type-B USB connector optional

• EXP1 & EXP2 have more multiplexing functions, such as USART, I2C, CAN

• SD card & USB upload support

• A 4.7kOhm 0.1% temperature sensor pull up resistor is used, PT1000 can be connected directly. For PT100, an amplifier board must be used.
