Detailed Description

Board hardware configuration for TMC51x0 Evaluation Kit.

Defines board-specific hardware parameters for the TMC51x0 Evaluation Kit. These values are used for automatic current calculation and power stage configuration.

Board-specific: These parameters depend on the TMC51x0 EVAL kit hardware:

• Sense resistor value (0.05Ω / 50 mOhm)
• Clock frequency (12 MHz internal clock)
• MOSFET characteristics (BSC072N08NS5: Miller charge ~6nC, BBM time ~100ns)
• Short protection defaults

Note: Supply voltage is motor-specific and should be set from MotorConfig, not BoardConfig. The board can handle 12-36V, but the actual voltage depends on the motor being driven.

These values stay the same regardless of which motor is connected or what platform it's used on.
