Feature: 1. Applicability: Based on the good ecology of RRF firmware and the onboard 7 axes (7xtmc2209), the board can be easily configured with a variety of models, such as Voron series, multi z axes models, dual x models, etc. 2. WiFi and Duet3D Supported: CAN FD bus supporting generation Duet3D expansion boards, smart tools and custom plug ins, switching between WiFi and Ethernet versions can be achieved by replacing modules. WiFi supports external antennas to set up your printer and update firmware via the web interface. 3. Connector: Xh2.54 connector is adopted, and the functions of each interface are exactly the same as mini5+. 4. Power: 7x PWM power MOSFET outputs (1 for hotbed, 2 for hotend, 4 for fan). 5. Power Supply: 28V maximum input, 12V at 2A DC‑DC (12V fan power supply), 5V at 8A DC‑DC (Raspberry Pi and system power supply), two 3 3V at 0.6A LDOs (for MCU and 3.3V peripherals respectively) powered by).
