Ramps 1.4
It has Cartesian robots and regulations of the extruder .
Extended to control other accessories.
Heater / MOSFET outputs and three fan thermistor circuit.
Integration of additional security 5A and component protection
Control of additional heating bed 11A fuse
Suitable for 5 Pololu stepper driver board
Pololu board pin socket, so they can be easily replaced or removed for future designs .
I2C and SPI pins left for future expansion.
Hooked into all MOSFET PWM pin versatility.
Servo type connector is used to connect to the end stop , the motor and the light-emitting diodes. These connectors are gold-plated , rated current of 3A, very compact.
On the SD card to add - is now available from the Kliment - Sdramps
LED indicate when the heater output

Ramps 1.6
Ramps 1.6 is optimized and launched based on Ramps 1.4 & Ramps 1.5
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.
