⚠️ Ultrasonic sensor always points forward; line trackers are fixed downward. This limits creative mechanical designs. ⚠️ Vendor lock-in: Some advanced blocks require Yahboom’s extension; generic micro:bit code may not control motors. ⚠️ Not officially supported by BBC: YoloBit is a third-party derivative; updates from Microsoft MakeCode may temporarily break custom blocks. ⚠️ Smaller community: Troubleshooting help is harder to find compared to standard micro:bit or Arduino (fewer Stack Overflow posts). ⚠️ Limited current for motors: The onboard motor driver typically supports up to 200mA per channel – fine for small TT motors, but not for high-torque or geared motors.

The YoloBit builds directly on the micro:bit V2 architecture but adds significant onboard peripherals. ⚠️ Not officially supported by BBC: YoloBit is
