- * To use TMC2130, TMC2160, TMC2660, TMC5130, TMC5160 stepper drivers in SPI mode
- * connect your SPI pins to the hardware SPI interface on your board and define
- * the required CS pins in your `pins_MYBOARD.h` file. (e.g., RAMPS 1.4 uses AUX3
- * pins `X_CS_PIN 53`, `Y_CS_PIN 49`, etc.).
- * You may also use software SPI if you wish to use general purpose IO pins.
+ * Trinamic Smart Drivers
  *
- * To use TMC2208 stepper UART-configurable stepper drivers connect #_SERIAL_TX_PIN
- * to the driver side PDN_UART pin with a 1K resistor.
- * To use the reading capabilities, also connect #_SERIAL_RX_PIN to PDN_UART without
- * a resistor.
- * The drivers can also be used with hardware serial.
+ * To use TMC2130, TMC2160, TMC2660, TMC5130, TMC5160 stepper drivers in SPI mode:
+ *  - Connect your SPI pins to the Hardware SPI interface on the board.
+ *    Some boards have simple jumper connections! See your board's documentation.
+ *  - Define the required Stepper CS pins in your `pins_MYBOARD.h` file.
+ *    (See the RAMPS pins, for example.)
+ *  - You can also use Software SPI with GPIO pins instead of Hardware SPI.
+ *
+ * To use TMC220x stepper drivers with Serial UART:
+ *  - Connect PDN_UART to the #_SERIAL_TX_PIN through a 1K resistor.
+ *    For reading capabilities also connect PDN_UART to #_SERIAL_RX_PIN with no resistor.
+ *    Some boards have simple jumper connections! See your board's documentation.
+ *  - These drivers can also be used with Hardware Serial.
