Open FFBoard TMC4671 driver kit (Without main controller)

The TMC4671 OpenFFBoard driver is the recommended reference motor driver for the Open FFBoard project.

The OpenFFBoard is intended for DIY direct drive steering wheels and other force feedback devices. See the resources below for more information about the project.

The Open FFBoard STM32F407 main controller is NOT INCLUDED. Please purchase it separately as it is required for operation.

It is recommended to also use the TMC4671+Open FFBoard Case to protect your system.

Included components:

• TMC4671 motor driver
• 50W 10r power resistor
• Plugin terminals
• Standoffs and screws
• Heatsinks

Specs:

• 12V-50V (36V-48V recommended)
• 30A current sensors (Use heatsinks >10A)
• Integrated brake resistor circuit for power supply protection
• (ALWAYS connect brake resistor to PB+/PB-)
• Very low sensing noise

Supported motors:

• 3 phase synchronous BLDC servo motors
• 2 phase stepper motors
• DC motors (Currently in development)

Supported encoders (for all motor types):

• ABN quadrature incremental encoder (recommended)
• SinCos analog encoder
• 3 phase analog encoder
• Hall sensors (NOT recommended)
• All encoders supported by OpenFFBoard firmware by position forwarding (experimental)
• BISS-C with rs485 addon
• MT6825, MT6835
• SSI
