Product Description:
The RUMBA Mainboard is featured with specific technical details including an input voltage recommendation of 12-24V, restricted input voltage of 6-35V, a stepping driver capable of supporting SPI socket StepStick, and six MOSFET outputs. It facilitates a maximum bed current and heater current of 20A and 5A respectively. The device includes provisions for five thermistor connections, six limit switches, and runs on Marlin bugfix-2.0 Firmware.
The ST820 Driver Board is a standout feature of this product. With a supply voltage ranging from 7V to 45V, it can generate output current reaching up to 1.5 A rms for each motor phase. The peak current regulation is facilitated through a trimmer. The form factor and its connectivity capabilities are compatible with RAMPS (RepRap Mega Pololu Shield) or similar devices.
This technology is based on the STSPIN820 driver that allows for stepper motor driving with a microstepping resolution up to 1/256th of a step. For safety, it includes overcurrent, short-circuit and overtemperature protections.
The package includes a rumba Mainboard, a USB Cable, and six ST820 drivers.
