32 bit Spider V3 board - for Voron - STM32F446 180Mhz

Spider Board is a small but powerful 3D printer control board. In a limited space, it integrates 8 stepper motor drives, 5A 12V power supply, 8A 5V power supply, which provides powerful energy for fans of various voltages, various RGB light strips and Raspberry Pi. You can build a 3D printer with rich functions through SPIDER. Especially for VORON V2.4, designed cooperating with the VORON team in the early stage of design, and many features have been recognized by the VORON team. If you are building VORON, this will be your best choice.

Current Version: 3

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 Hot-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.

Version 3 upgrades:

• Added 74HCT365 buffers for all stepper motor drive signals. All motor driver IO signal voltages change from 3.3V to 5V, driveability is improved, and external driver connection is easier.
• An integrated CAN transceiver is added to allow the motherboard to communicate directly with CAN devices, without the need for expansion boards.
• A 3.3V power supply indicator is added, and different power supplies are indicated by different colored LEDs, so that the working status of each power supply on the motherboard can be seen at a glance.
• The main board has been redesigned and all markings are placed on the top layer, making it easy for users to see the pin markings and making firmware configuration easier.
• Connect the BOOT0 and RESET pins of the STM32 to the IO of the Pi via the switch (disconnected by default), which provides the basis for directly entering programming mode via the Pi.
