Feature:
Type:Mini-Rambo 1.3 Mainboard Set
Quantity:1 Set
1. Compatible Atmega2560 and Atmega32u2 processors are compatible with all RAMPS class firmware.
2. Crystals for both usb and mcu (timing accurate to 10ppm).
3. 4 Thermistor jacks.
4. All extra pins broken out on both processors (allows using the 32u2 for LUFA AVR programmer, etc.).
5. 2 channel SDRAMPS compatible SPI breakout.
Motor Drivers
1. 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).
2. Digital Trimpot for stepper current control.
3. Current limit on driver IC VCC to prevent permanent latchup.
4. Microstep mode configured by MCU through firmware (no jumpers needed).
5. Test points for driver control signals.
6. Step and Direction pins are on their own ports for synchronous movement.
Capability
1. 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).
2. PWM DC outputs (Extruders, Fans, etc.)
6 Outputs
1. Low resistance mosfets for cool running.
2. Indicator led for each channel.
Power
1. Three independent power rails for flexible input power configurations.
2. Heated Bed, 15A 12-24V (version earlier than 1.1 limted to 14A 16V due to fuse rating, see rambo_development for hacks).
3. Extruders and fans, 5A 12-24V (fuse can be exchanged for up to 10A capacity) 10V-26V input voltage.
4. Motors, 5A 12-24V (fuse can be exchanged for up to 10A capacity) 10V-26V input voltage.
5. Built in SMPS for 5V generation.
PCB
1. 4 Layer.
2. 2oz copper on all layers.
3. High quality
