Mini-Rambo 1.3 Mainboard Integrated Controller Board + 4pcs Heatsinks For Prusa i3 MK2 3D Printer

Description:

RAMBo (RepRap Arduino-compatible Mother Board) is an all in one RAMPS class motherboard targeting convenience, reliability, and performance.

Features:

Logic

- Arduino MEGA compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware

- Crystals for both usb and mcu (timing accurate to 10ppm)

- 4 Thermistor jacks

- All extra pins broken out on both processors (allows using the 32u2 for LUFA AVR programmer, etc.)

- 2 channel SDRAMPS compatible SPI breakout

Motor Drivers

- 5 A4982 1/16th microstep motor drivers (A4984 1/8th prior to v1.1) (2 connectors on Z for Prusa Mendel and other dual Z printer designs)

- Digital Trimpot for stepper current control

- 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

- Extra driver ports broke out for up to 3 additional drivers (some of the motor extension pins are shared with max endstop and a pin allocated for SPI-SS extensions)

PWM DC outputs (Extruders, Fans, Etc.)

- 6 outputs

- Low resistance mosfets for cool running

- Indicator led for each channel

Power

- Three independent power rails for flexible input power configurations

- Heated Bed, 15A 12-24V (version earlier than 1.1 limted to 14A 16V due to fuse rating, see rambo_development for hacks)

- Extruders and fans, 5A 12-24V (fuse can be exchanged for up to 10A capacity) 10V-26V input voltage

- Motors, 5A 12-24V (fuse can be exchanged for up to 10A capacity) 10V-26V input voltage

- Built in SMPS for 5V generation

PCB

- 4 layer

- 2oz copper on all layers

- High quality, High temperature FR4-TG130 PCB

- Gold ENIG finishing
