About Ramps 1.4:

– MOSFET controllers / outputs and three thermistor circuits.

– ADDITIONAL SECURITY INTEGRATION 5a and component protection

– Control of additional heating bed 11a fuse

– Suitable for 5 polom step by step

– Pololu pin socket, so they can be easily replaced or removed for future designs.

– I2C I2C and SPI for future expansion.

– Connected to all MOSFET PWM versatility.

– SERVO type connector is used to connect to the final stop, the motor and the light emitting diodes. These connectors are gold plated, nominal current of 3a, very compact.

– On the SD card to add-is now available from the Kliment-sdramps

– LED indicates when the heater output

– Option 2 motors connected to z prusa Mendel

About Limit switch parameter:

– Using 22 AWG wire, copper wire inside is very thick, can be resistant to current voltage 2a, 300V.

– An insulating layer over a wide range of temperatures, up to 80 degrees.

– Plug it convenient, to facilitate the use

– Network connection VCC network (+ ramps)

– Connect the black GND cable (de-ramps)

– Green line connection signal (ramps in s)

– Tips: Under normal circumstances, the system must be configured for at least three mechanical switches.

– Advantages: Easy to install, the most common styles.

About LCD 12864:

3D printer using LCD control panel, are ramp extension accessories. The LCD control panel through which you can get spooling is that the 3D model files are copied to the SD card, and print the file through the LCD control panel.

About A4988 driver:
