  • 4 layers PCB, optimize heat dissipation
  • Input voltage: 12V
  • Power: 270W
  • Can be extended to LCD and other parts
  • There are heater and fan MOSFET outputs and 3 thermistor interfaces
  • 5A greater safety and fusion protection component
  • Heated bed additional checks 11A fuses
  • Pololu design pin socket socket can be easily replaced or removed for future design
  • I2C and SPI pins are available for future expansion
  • Servo connectors are used for connecting limit stops, motors and light-emitting diodes. These connectors are gold plated and have a nominal current of 3A, which is very compact
  • LED lights up when the heater has an outlet
  • Size: 101.5 * 60.5mm
  • Support motor drivers: support A4988 DRV8825 and other motor drivers(support five motor drivers Simultaneously)
  • Patch MOS tube: B55NF06


  • The RAMPS 1.6 is the second RAMPS iteration released by BIQU/BIGTREETECH.
  • It replaces the original green power connector with a pair of screw terminals, adds a larger heatsink over the MOSFETS, and has a larger bed MOSFET.
  • It maintains the surface-mounted fuses and flush MOSFETS of the RAMPS 1.5.
  • The positions of the D1 and D2 diodes have been swapped from the positions in RAMPS 1.4, the D1 diode is now the diode closest to fuse F2. The same is true for RAMPS 1.5, also manufactured by BIQU/BIGTREETECH.
  • The Struture almost same as Ramps 1.5 , the difference is Ramps 1.6 have new 2pin connectors,which more simple and convenient to connect,also will not be burnt easily,what’s more ,Ramps 1.6 have a good Heatsink above MOS tube in order to give a better function to heat dissipation.Beside, the Power of Ramps 1.6 is more larger than Ramps 1.5, the largest power will be up to or 270W , and Ramps 1.5 just can be up to 200W, or samller than 200W.
