M5Stack BTC Standing Base for M5 Core with integrated SHT30

The M5Stack BTC Standing Base holds an M5Stack Core at an angle, for example as a desk station. It has a built-in Sensirion SHT30 temperature and humidity sensor and powers the Core via USB Type C. The Core plugs in via the pin header on the underside.

Note: M5Stack Basic and Gray can be attached, but are only powered via the base, their battery is not charged. To charge, plug the USB cable into the Core itself. Do not connect other sensors with I2C address 0x44, such as an ENV unit with SHT30, otherwise there is an address conflict.
