FAQ
Q1: Regarding the “pinctrl: not found” error.
If you encounter the error:
pinctrl: not found
It indicates that you have installed the Bullseye system. It is recommended to install the Bookworm system instead.
Q2: About the Battery Charger?
To charge the battery, simply connect a 5V/2A Type-C power supply to the Robot Hat’s power port. There’s no need to turn on the Robot Hat’s power switch during charging. You can also use the device while charging the battery.

During charging, the input power is boosted by the charging chip to charge the battery and simultaneously supply the DC-DC converter for external use, with a charging power of approximately 10W. If external power consumption remains high for an extended period, the battery may supplement the power supply, similar to using a phone while charging. However, be mindful of the battery’s capacity to avoid completely depleting it during simultaneous charging and usage.
