M5StickC Yun Hat(SH20,BMP280,SK6812)

The YUN HAT is an eye - catching cloud - shaped base that measures environment information. It comes with a built - in temperature and humidity sensor SHT20, an air pressure sensor BMP280, and a photoresistor. There are 14 SK6812 4020 RGB LEDs on board. The board has an embedded microprocessor STM32F030F4, which offers concise and efficient program APIs. With its beautiful appearance, it can be a great decoration for your space. Designed for the M5StickC, it's compatible with the top socket of M5StickC. The three - layer structure design is very practical. The upper and lower PCB boards are for fixing and the main circuit respectively, ensuring long - term circuit operation. There's also an independent external power interface. The middle layer is a light - guided acrylic component. Its outer contour cutting surface is partially polished to reduce light scattering and achieve a more even and saturated light effect. The board has one hook hole and two 6*4mm magnet mounting positions, allowing you to easily place it anywhere. Key features include compatibility with M5StickC, on - board microprocessor STM32F030F4, various sensors, RGB LEDs, a three - layer structure, and support for Arduino and UIFlow (Blockly, Python) development platforms. It comes with 1x YUN HAT and 2x Dupont. Applications include environmental information collection, smart home decoration, and fridge magnet use.

Using the YUN HAT is easy. First, connect it to your M5StickC through the top socket. You can use the independent external power interface if needed. To collect environmental information, the built - in sensors like SHT20 and BMP280 will do the job automatically. For the RGB LEDs, you can use the Arduino or UIFlow (Blockly, Python) development platforms to program different light effects. When it comes to placement, you can use the hook hole to hang it or the magnet mounting positions to stick it to a metal surface. As for maintenance, keep it in a dry and clean place. Avoid exposing it to extreme temperatures or moisture. If there's dust on the acrylic part, you can gently wipe it with a soft cloth. That's all you need to know to make the most of your YUN HAT.
