The BTC is a M5 Base that allows you stand your M5 Core instead of laying them down or hang on the wall. BTC is not just a seat for holding the M5 Core but also comes with serveral features like temperature and humidity detection (by SHT30), and charging base. Note * Although M5Stack BASIC and GRAY Core can be attached to the base, but BTC can not charge them. After plugging-in a USB cable, the Core is powering without any charger. * Once M5Stack Core has been attached to BTC, it can not connect to an ENV Unit. This is to avoid I2C address conflict with built-in SHT30 sensor of BTC Base.
