 Charging Instruction
 When used with first-generation Core series controllers such as Basic:
- The USB port of the Base BTC base only supplies power to the host device.
  - To charge the lithium battery inside the Base Bottom, please connect the USB port on the host device.
 
 I2C Address Conflict
 - Do not connect additional sensors with the same I2C address (0x44) as the SHT30 on the I2C bus, otherwise the device will not work properly due to address conflicts.
