# Case Assembly

# Assemble Your EP1 Hardware

Follow the steps below to assemble your EP1 hardware and prepare it for setup.


## Step 1: Assemble the Case


### What you’ll need:

* Case back
* Ball joint
* Locking ring
* Stand

### Insert the Ball Joint


1. Insert the **ball joint** through the front side of the case back.

2. While holding the ball joint in place, thread the **locking ring** over the ball joint from the rear.

   **Tip**: The locking ring has a slight groove—ensure this faces the back of the case.

   The ball joint should feel snug but remain adjustable with moderate pressure. This allows for positioning flexibility.![](https://docs.everythingsmart.io/api/files.get?sig=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJrZXkiOiJ1cGxvYWRzLzEyODlhY2JjLWM2NWItNGNhNy05YjA0LWI3YjZmYzc5ZjFiNS84ZDY5NjNjMy1lOWJiLTQ0MjEtYWZkOS1kYzFiMDNlZTQzMzAvaW1hZ2UucG5nIiwidHlwZSI6ImF0dGFjaG1lbnQiLCJpYXQiOjE3OTM2ODExMDAsImV4cCI6MTc5Mzc2NzUwMH0.Ya2a5pOZnXDgpQBH-W9aZHIVujxc3jXsKYN8ZFvp_Ao)

You may find the fit tight initially due to the 3D printing process. This will ease over time with movement.

## Step 2: Install the Board and Sensors

### What you’ll need:

* EP1 Board
* mmWave Sensor (SEN0395 or SEN0609)
* PIR Sensor

### Insert the EP1 Board


:::tip
Photos may show the stand removed for clarity—this is not required.

:::


1. Press the **EP1 board** into the back of the case until all four corners click into place.

### Insert the mmWave Sensor

Identify your EP1 board revision and sensor type before continuing:

For Dual Slot Boards (Rev 1.3/1.4)

* Compatible only with **SEN0395 (6-pin)** sensors
* Insert into either slot:
  * **Top slot**: Wider horizontal field of view (recommended)
  * **Side slot**: Wider vertical field of view

For Single Slot Boards (Rev 1.5)

* Compatible with **SEN0395 (6-pin)** and **SEN0609 (5-pin)**

Insert based on your sensor:

* **SEN0395 (6-pin)** → Insert to the **far left**; align the V pin with the 5V on the board
* **SEN0609 (5-pin)** → Insert to the **far right**; align the VIN pin with the 5V on the board


:::warning
**Important**: Always align the 5V pin correctly. Incorrect insertion may damage the sensor.  
  
**Handle with care.** Pins can bend easily—remove the sensor when adjusting the board or enclosure.

:::

### Insert the PIR Sensor


1. Push the **PIR sensor** into the center socket on the EP1 board. It only fits in one orientation—do not force it.

When both sensors are installed, your board should resemble the image below:

## Step 3: Complete the Case


1. Clip the **front cover** of the case into place until it snaps securely.  
   ▸ Ensure all corners are fully closed.

Your EP1 is now fully assembled and ready for power.


## Step 4: Power On the EP1

### What you’ll need:

* USB-C cable
* Power brick (any charger providing \~200mA)


1. Connect the USB-C cable to the EP1.
2. Plug the other end into the power brick.  
   ▸ A red LED on the front of the device will illuminate when powered on.

You’re now ready to proceed with the setup process
