Product Description:
This product is a Rumba mainboard featuring an input voltage that is recommended within the range of 12-24V but can tolerate a limit of 6-35V. The stepping driver can cater to six at a time, provided they support SPI socket StepStick. There are also six MOSFET outputs.
The board unprecedentedly bears a capacity of managing a maximum bed current of 20A and a maximum heater current of 5A. For thermistor connections, it provides five, along with six limit switches. The utilized firmware for this motherboard is Marlin bufix-2.0.
In addition, this package includes a TMC2130 V1.1 driver. This versatile device provides mechanisms for adjusting the working current of the two-phase stepper motor, with a single-phase current of 1.2A, (peak value reaching up to 2.5A) and only supports SPI. Its motor can accept an input voltage lying in the range of 4.75~46V while the logic interface input voltage is within 3~5V.
The TMC2130 V1.1 driver offers a high subdivision of 256. One of its unique features is quiet operation, combining optimal motor torque and maximum efficiency. It also integrates high-precision sensorless motor load detection. Notwithstanding the high load drive, the driver ensures it never gets out of sync. Notably, it can help to reduce energy consumption by a staggering 75%.
The package includes the following items:
- Rumba Mainboard
- USB Cable
- TMC2130 driver (quantity: 6)
