PCB Assembly & First Boot

Connect the PCBs

The Satellite1 comes in 2 pieces:

  • The "Hat" (round board)
  • The "Core" (rectangular board)

You'll notice a standard Raspberry Pi 40-pin connector on the Hat board (marked in red). Carefully align the Core board's 2 rows of pins with the Hat's 40 pin connector and press them together.

Mount Core to Hat

(Optional) mmWave Presence Sensors

The Satellite1 HAT has two ports for optionally mounting external mmWave presence sensors: LD2410 or LD2450. Please read more about setting up and calibrating your presence sensors here.

First Boot - Powering On

The below instructions assume you have connected the HAT to the CORE and are powering the Satellite1 for the first time:

  1. Take a USB-C cable and plug one end into the USB socket on the Hat labeled "CORE/ESP".
  2. Plug the other end into a 9V USB-C power supply (if you want to power a speaker from the HAT), or a computer 5V USB-C connection (if you're plugging into the headphone jack).
  3. Upon first boot, you will see the blue LEDs count down clockwise as the device flashes the XMOS audio processor.
  4. Finally, the LEDs will begin to sparkle a warm white color. Congrats! Move to the next step.
