Tested on a [Bigtreetech TMC2209 V1.2](https://github.com/bigtreetech/BIGTREETECH-Stepper-Motor-Driver/tree/master/TMC2209/V1.2) and [Bigtreetech TMC2209 V1.3](https://github.com/bigtreetech/BIGTREETECH-Stepper-Motor-Driver/tree/master/TMC2209/V1.3).

It has a rSense of 110 mOhm and it uses one Pin (PDN_UART) for UART RX and TX.
So the PD_UART-Pin needs to be connected to the Raspberrry Pis RX-Pin directly and to the TX-Pin with an 1kOhm resistor.
So the PDN_UART-Pin needs to be connected to the Raspberrry Pis RX-Pin directly and to the TX-Pin with an 1kOhm resistor.
You can read more about this in the datasheet from Trinamic.

Because the TMC2209 uses one shared pin for transmit and receive in the UART communication line, the Raspberry Pi also receives what it sends.
