Introduction:
TMC2130 V2.0 is a new module that is optimized and upgraded to solve the problem that older drivers cannot choose to use the SPI working mode.
TMC2130 V2.0 Upgrade point:
1. SPI working mode of TMC2130 2.0 can directly select driver current, driver subdivision and other parameters through firmware, which makes these parameters more accurate. Using sequexternal sequencers, it can greatly reduce the workload of the chip and effectively avoid problems such as running deviation, losting step and fault caused by the overload of the chip.
2. The newly upgraded driver, its chip is at the bottom, which can better dissipate heat
3. This module is similar to TMC2100, which will generate a lot of heat energy when it working.

Working mode description:
1.STEP/DIR mode:
1.1 SPI position welding 0Ω resistor, making the driver work in STEP/DIR mo
1.2 Work mode selection:SDI(CFG1)/SCK(CFG2)
Note:
In order to enhance the compatibility of drivers, long pin row pin is used in production. When the user uses STEP/DIR mode, it is necessary to check whether the CFG1 pin on the motherboard has connection resistance. If so, it is necessary to remove the resistance or cut off the pin.2. SPI working mode wiring instructions:
Before wiring, it is necessary to select the hardware operation mode of the driver module
2.1 Solder CFG4 and CFG5 as shown in the red area ( CFG4 is connected to GND and CFG5 is connected to VCC); (Welding is correct to enable spreadcycle mode)
2.2 Remove the resistor at the SPI position to put the driver in SPI mode.
The wiring diagram is as follows:
The wiring diagram is as follows:
Found the Aux-3 expansion port on the main board , and the corresponding pin was connected:
