![]() ![]() Limit switch socket 24V/5V/3.3V optional, ready for more other equipment, such as -inductive sensor, BL-Touch.Two car fuses for hot bed input and main power input.V2.2: 28V input DC-DC for DC-DC for mcu and RGB, Two LDO for MCU and motors.V1.0&V1.1: 28V input DC-DC, DC-DC (Especially for Raspberry Pi), LDO.Improved TMC jumper settings again,simpler and easier.V2.2:Add Two 60V-Max stepper driver slot.8 TMC stepper drivers support, with Uart&SPI support.Based on STM32F446 180Mhz,all IOs can withstand 5V voltage.Re-layout the PCB, connectors position changed.All motor drive module interface communication networks add high voltage buffering and voltage clamping processing, adding a shield to the MCU.Optimize the fan control circuit, upgrade the buffer chip to independent triode control, enhance stability and greatly improve safety performance.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.Add pin definition silkscreen on the bottom.Add two thermistor sockets, a total of 6.Change the Raspberry Pi 5V (3A to 5A) and system 5V(5A to 3A ). ![]() Change the series diode of the driver circuit to a 15A fuse(1808).Change the Raspberry Pi 5V and system 5V to separate DC-DC circuits (3A per channel).Add TVS and Bleeding resistance to every stepstick socket.It is USB power-supply port without USB signal. You can solder the below USB port, then you can power-up RPI with a USB-A cable. Switch EXP1 & EXP2 mark(Only mark, not socket)Īdd room for RaspberryPI USB-A power supply port.If you are building VORON, this will be your best choice. Especially for VORON V2.4, we cooperated with the VORON team in the early stage of design, and many features have been recognized by the VORON team. You can build a 3D printer with rich functions through SPIDER. 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. SPIDER is a small but powerful 3D printer control board. ![]()
