SPIKE Compatibility Mode

When the communication protocol is switched to SPIKE mode, the module simulates the output of a SPIKE color sensor. The K210 will generate corresponding color values, reflectance, and RGB data based on the current AI recognition mode.

_***Note: **_When in SPIKE mode, the module must be connected to a SPIKE device. If not connected, the module will not function properly. To reset to factory settings: First, disconnect the power supply. Hold down the button without releasing it while plugging in a Type-C charger. Once the boot screen appears, release the button to restore default configurations.

When the port protocol is switched to SPIKE mode, the K210 simulates the output of a SPIKE color sensor. In different vision modes, the meaning of the color value, reflectance, and RGB values is as follows:

Mode

Color Value

Reflectance

R Value

**G Value **

**B Value **

Additional Notes

  • <font style="background-color:rgba(255, 255, 255, 0.05);">Color Value</font> corresponds to the color index defined in the SPIKE protocol.

  • Reflectance is calculated as <font style="background-color:rgba(255, 255, 255, 0.05);">(R+G+B)/255 × 100</font>, giving a value between 0–100.

  • For unused fields (e.g., Deep Learning, Wi-Fi), RGB values may be 0 or random.

  • In Line Recognition mode, only the lowest detected line is reported back to SPIKE.
