The TMCM-BB1 and TMCM-BB4 are BaseBoards for Trinamic’s Slot Type Modules. TMCM-BB1 is a single-axis board and provides access to one MCU Module and one Driver Module. TMCM-BB4 is a 4-axis board and provides access to 4 + 1 modules slots. The single 36-pin PCI socket is available for the TMCM-0930 module, the main MCU (ARM Cortex-M4) module for the whole system. Other (four) 98-pin PCI socket is accessible for Slot Type motor driver Modules, available as stepper (TMCM-1230; TMCM-1231) or BLDC (TMCM-1637; TMCM-1638) versions. This BaseBoard comes with communication interface options like CAN; RS485 and USB-C, plus separate GPIO headers for both insertable modules.
