Satellite1 Dev Kit

The Satellite1 Dev Kit contains the two boards necessary to build your own completely private voice assistant & multi-sensor with advanced audio processing & music playback.  Add your own speaker, mmWave sensor and power supplies.  Print the speaker enclosure at home!

This Dev Kit focuses on controlling your smart home via the Home Assistant platform and their incredible Assist voice control pipeline.

Satellite1 HAT Board:

Features 4 high-performance microphones powered by an XMOS audio processing chip, enabling clear audio capture even in noisy environments. Additionally, the HAT boasts 4 programmable buttons, a headphone jack, and a robust 25W speaker amplifier. It even acts as a multi-sensor by measuring room temperature, humidity, luminosity, and presence when paired with a mmWave radar sensor.

• Powerful Audio Processor: XMOS XU316 with 16-Core 32-Bit RISC running at 800 MHz. 3200MIPs
• Memory: 1024 KB SRAM, 8 MB Flash
• LEDs: 24x WS2812 programmable RGB LEDs 
• Microphones: 4x PDM MEMS microphones
  
• Buttons: 4x Tactile buttons with one hardware controlled mute, for security
  
• Line level audio output: PCM5122
• 25W Mono speaker output: TAS2780
• USB Power delivery, up to 100W: FUSB302
• Ambient Light sensor: LTR-303ALS
• Temperature and Humidity sensor: AHT20
• Millimeter Wave Radar Presence Detection: Attach your own LD2410 or LD2450
  
• Expandability: 40-pin GPIO HAT connector, 2 USB Type-C ports, 80-pin accessory connector for upcoming FutureProofHomes mini-speaker, amplifier and in-ceiling mount (more info coming soon).
• Hardware owned by you. No vendor lock-in, or planned obsolescence.
  
• Power Requirements: The complete assembly requires up to 30W of power at maximum consumption, when using a 20-25W speaker. We recommend at least a 30W power supply, that can deliver 20V @ 1.5A or greater.

Satellite1 Core Board:

The Satellite1 Core Board contains the ESP32-S3 N16R8 processor and Wifi/Bluetooth connections.

• Powerful Processor: ESP32-S3 N16-R8 WROOM 1 with dual-core 32-bit LX7 running at 240 MHz.
• Memory: 384 KB ROM, 512 KB SRAM, 16 MB Flash, 8 MB PSRAM
  Raspberry Pi Compatibility: Supports most Raspberry Pi HATs, eliminating the need for a Raspberry Pi board.
• Open-Source Platform: Flexibility for customization and community-driven development.
• Compact Form Factor: Mimics the Raspberry Pi Zero form factor with additional onboard features.
• Wireless Connectivity: Built-in 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth® 5 (LE) support.
• Multi-Language Programming: Arduino IDE, MicroPython, and CircuitPython compatibility.
• Expandability: 40-pin GPIO breakout, USB port with 2 connectors (one Type-C, and one Micro for compatibility), programmable Red LED.
• User-Friendly Design: Features diagnostic LED’s, boot and reset buttons for easy setup and troubleshooting.
• All 31 GPIO accessible: 28 exposed to the RPi 40 pin header, and 3 exposed as pads.
• Hardware owned by you. No vendor lock-in, or planned obsolescence.
