Using the MikroElektronika Feather Click Shield is easy. First, you need to have your Feather main board ready. Then, select the Click board you want to use from the over 750 available options from MikroE. Place the Click board on top of the mikroBUS socket on the shield and just 'click' it in. You're then ready to start prototyping with your chosen peripheral device. When choosing Click boards, make sure to avoid those with 5V logic output. These can potentially harm input pin 3 on your Feather. Since MikroElektronika doesn't offer Python, Circuit/MicroPython, or Arduino libraries for their Click boards, you'll have to either adjust their C libraries or find new ones. As for maintenance, keep the shield and Click boards in a dry and clean place. Avoid exposing them to extreme temperatures or moisture. This will help keep your Feather Click Shield and Click boards in good working condition for a long time.
