# Install Libraries

The Feather Sense is packed full of sensors. If already have CircuitPython installed on your Feather Sense, next you'll need to install a base set of CircuitPython libraries to use the features of the board with CircuitPython.

Follow these steps to get the necessary libraries installed.

### Installing CircuitPython Libraries on your Feather Sense

Firstly, [download the CircuitPython library bundle](https://circuitpython.org/libraries) that matches your version of CircuitPython from CircuitPython.org. The libraries [bundle for old CircuitPython 8.x is available here](https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/download/20250213/adafruit-circuitpython-bundle-8.x-mpy-20250213.zip).

The bundle downloads as a .zip file. Extract the file anywhere on your PC/Laptop. Open the resulting folder.

Open the **lib** folder found within.

Once inside, you'll find a lengthy list of folders and **.mpy** files. To install a CircuitPython library, you drag the file or folder from the bundle lib folder to the **lib** folder on your **CIRCUITPY** drive. If you do not already have a **lib** folder on your **CIRCUITPY** drive, create one now.

Copy the following folders and files from the bundle **lib** folder to the **lib** folder on your **CIRCUITPY** drive:

* **adafruit\_apds9960**
* **adafruit\_bmp280.mpy**
* **adafruit\_bus\_device**
* **adafruit\_lis3mdl.mpy**
* **adafruit\_lsm6ds**
* **adafruit\_register**
* **adafruit\_sht31d.mpy**
* **neopixel.mpy**

Your **lib** folder should look like the image below. These libraries will let you run the demo sensor data acquisition program.
