Prettyia 3D Printer Accessories Mini-Rambo 1.3A Motherboard Mainboard

Description:

- This board is based off RAMBo, the Arduino MEGA design, and the work of RepRap community,It has 4 stepper drivers and 4 mosfet switched outputs.

- Arduino MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware Crystals for both usb and mcu (timing accurate to 10ppm).

- 3 Thermistor jacks,Motor Drivers,4 A4982 1/16th microstep motor drivers(2 connectors on Z for Prusa Mendel and other dual Z printer designs).

- PWM Outputs for (XY), Z, E0 stepper current control instead of digital trimpot,Current limit on driver IC VCC to prevent permanent latchup

- Microstep mode configured by MCU through firmware (no jumpers needed) Test points for driver control signals,Step and Direction pins are on their own ports for synchronous movement capability PWM DC outputs (Extruders, Fans, Etc.)

- 4 outputs (1 Extruder, 1 BED, 2 low power (fan,etc) Low resistance mosfets for cool running Indicator led for each channel.
