Introduction

The Satellite 1 Developer Kit is the first version of our private voice assistant hardware and is the foundation for the larger ecosystem we're building. The Dev Kit comprises of two PCB boards that we call the "Hat" (round board) and the "Core" (rectangular board). When you connect these two components together you get the Satellite1 Dev Kit.



Animation shows how to attach the rectangular Core Board to the round Hat Board, with an optional mmWave presence sensor.

Your Satellite1 Dev Kit can also be installed in one of our many enclsoures and speaker kits to become a more complete product. Read more here.

Satellite1 vs. Home Assistant Voice Preview Edition

The following table compares the main features of the Sat1 and Home Assistant Voice PE products. Both products run the same ESP32-S3 and XMOS chip. Our firmwares are also extremely similar (by design, to increase engagement and keep the community moving together). We think it is fair to say that the Sat1 is more feature rich and produces better sound. Read below:

Feature Satellite1 Home Assistant Voice PE
Microphones Four high-performance microphones (XMOS firmware uses two microphones currently. Future firmware upgrade will utilize all 4 microphones). Two microphones designed to hear voice commands in most environments.
Speaker Output 25W speaker amplifier capable of 48 kHz audio streaming. Also allows 3.5mm jack for external speakers. Built-in 3W speaker for 48 kHz playback; includes a 3.5mm stereo jack for external speakers.
Environmental Sensors Includes room temperature, humidity, and luminosity sensors; supports adding mmWave presence detection (LD2410 or LD2450). Primarily focused on voice assistance; does not include additional environmental sensors.
Form Factor Available as a development kit with 4 buit-in buttons and components for assembly; official enclosure planned for future release. Comes in a ready-to-use injection-molded case with physical controls, including a mute switch and volume dial.
