Miscellaneous3d printer accessories motherboard kit for mega 2560 R3 + A4988 with heat sink usb cable kit
This super kit is designed for 3d printer controlling. Oblique interfaces with the powerful MEGA platform, and has plenty of room for expansion.Â
- It has Cartesian robots and extruder regulations.
- Extended to control other accessories.
- Heater / MOSFET outputs and three-fan thermistor circuit.
- INTEGRATION OF ADDITIONAL SAFETY 5A and component protection
- Additional heating bed fuse control 11A
- Suitable for 5 stepper driver board
- Plug with board pins, so they can be easily replaced or removed for future designs.
- The I2C and SPI pins are left for future expansion.
- Hooked on all the versatility of the MOSFET PWM pin.
- These connectors are gold plated, 3A current rating, very compact.
- On the SD card to add – already available in kliment-sdramps

3D printers use LCD control panel, they are ramp extension accessories. This version is an improved version of the reprap smart controller.
High quality 22AWG custom connection with wire, the inner copper wire is very thick, it can be resistant to 2A current, 300V voltage. It is the common connection of thin copper wire that cannot match.Â
- Red line connecting VCC (+ ramps)
- Connect the black wire GND (ramps-)
- Green line connection signal (ramps in s)
- Tips: Under normal circumstances, the system should be set to at least three mechanical switches.
- Advantages: Easy to install, the most common styles.
- Advantages: easy to carry and disassemble mechanical parts, the service life is shorter.
A4988 is a complete microstepping motor controller with built-in translator for easy operation. The A4988 converter is the key to easy application. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. In micro-step operation, A4988 chop control inside automatically selects the current decay mode (slow or mixed). The mixed decay current control scheme reduces audible motor noise, increases step accuracy, and reduces power consumption. Internal circuit protection includes: hysteresis thermal shutdown, low voltage lockout (UVLO), and cross current protection. A4988 surface mount QFN package, a size of 5mm × 5mm, nominal package height 0.90mm, with an exposed pad for increased heat dissipation.Â
