Detailed Description

Board hardware configuration for TMC51x0 Break-Out Board (BOB)

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

Board-specific: These parameters depend on the TMC51x0 BOB hardware:

• Sense resistor value (0.11Ω / 110 mOhm - typical for BOB)
• Clock frequency (12 MHz internal clock)
• MOSFET characteristics (typical MOSFETs: Miller charge ~30nC, BBM time ~200ns)
• Short protection defaults

Note: BOB boards may vary. Adjust these values based on your specific BOB hardware. Common BOB configurations use 0.11Ω sense resistors and standard MOSFETs.

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.
