NOTE:
- As a very light component, the pins are a bit fragile, so be careful when you using them, if you'll be plugging in or out often, you'd better secure them to your surface.
- If you are planning on using this for a bread board, jumper wires will need to be soldiered to the leads in order to make a secure connection.
