## Introduction FYSETC BIG DIPPER motherboard, reprap firmware(RRF), 32bit 3d pirnter motherboard base on DUET3 mini5+ and mini2+. Based on the good ecology of the RRF firmware and on-board 7-axis (7xTMC2209), the board can be easily configured in a variety of 3D printer models, such as VORON series, Annex Engineering K3, multi-Z-axis models, double-X models etc. ## Features - Size: 148.5 x 87mm - Based on same54p20 (arm cortex M4 @ 120mhz), it is fully compatible with duet3 mini5 + - Onboard 7-way tmc2209 stepper motor drive - Input / output IO full TVs protection - 28V maximum input, 12V@2A DC-DC (12V fan supply), 5V@8A DC-DC (power supply for raspberry pie and system), two 3 3V@0.6A LDO (power supply for MCU and 3.3V peripherals respectively) - Two automotive fuses for hot bed input and main power input - Using xh2.54 connector, the functions of each interface are completely consistent with mini5 + - 7x PWM power MOSFET output (1 for hot bed, 2 for hot end, 4 for fan,) - Reprap discount smart controller compatible sockets, Exp1 and exp2. It supports monochrome displays such as 200412864. - Uart1 raspberry PI row needle (including 5V@5A Power supply) - 2x4 row pin lead out for external SD card module - On board TF card slot - Type-C USB socket - 3 Thermistor/PT1000 inputs and support for 2 PT100 or thermocouple inputs via the optional daughterboards. - Both Wifi and Ethernet versions
CAN-FD bus that supports the next generation of Duet3D expansion boards, smart tools and custom addons.Set up your printer and update the firmware through the web interface.All common 3D printer geometries are supported Support for a wide range of Z probes including DC42’s IR Z probe and the Duet3D Smart Effector for delta printers.  ## Specification | Specification | Details | Specification | Details | |---------------|---------|---------------|---------| | Size | 148.5 x 87mm | Microprocessor | Aarm cortex M4 @ 120mhz | | Drivers | TMC2209 | Input / Output | IO full TVs protection | | Input Voltage | 28V (max) | Firmware support | Duet 3 Mini5+ | | Socket | USB Type-C | Output | 7x PWM Power MOSFET |
