Product Features Ramps 1.6 is a 4-layer board. It can be expanded to LCD screen and other parts. There are MOSFET heater and fan outputs and 3 thermistor interfaces. 4. Additional 5A safety and component protection. The heated bed control has additional 11A fuses. 6. Applies to 5 stepper drivers. 7. The flat pin socket can be easily replaced or removed for . I2C and SPI pins are available for expansion. Servo connectors are used to connect limit switches, motors, and LEDs. The connectors are gold-plated and have a rated current of 3A, making them very compact. 10. The LED lights up when the cooler has an output. Product Parameters Support for Motor Drivers: Supports A4988, DRV8825, and other motor drivers (supports five motor drivers simultaneously). Input Voltage: 12V Power: 200W MOS Tube Patch: B55NF06 RAMPS 1.6 is optimized and launched based on Ramps 1.4 and Ramps 1.5 by . The structure is almost the same as Ramps 1.5, the difference is that Ramps 1.6 has new 2-pin connectors, which are simpler and more convenient to connect, and will not burn as easily. Additionally, Ramps 1.6 has a heatsink above the MOS tube for better heat dissipation. Furthermore, Ramps 1.6's power is greater than Ramps 1.5; the maximum power will be up to or 270W, while Ramps 1.5 can only handle up to 200W, or less than 200W. Note: Only with 4 drivers. Select 2 motors to connect to Z PrusaMendel. Note: 1. If plugging in a TMC2100 driver, do not insert a short-circuit cap under the driver. 2. Regardless of whether it's ramps 1.5 or 1.6, compared to all drivers, the TMC2130 is the quietest.
