theBRAIN

Kits

Expansion kits for sense, GPS, archive, night vision, and larger storage. Far-field voice, dual movable face cameras, and Hailo-8L vision on BRAIN/MAX/OMNI (watch while you talk) already ship in the core box โ€” kits do not re-sell those as upsells. PRO is the AI HAT+ 2 GenAI specialty path.

Flatlay of intended theBRAIN expansion kits

Hardware lists

Concept BOM from the frozen kit research. Flatlays show real circuitry where we have locked plates โ€” more kits get images as we verify each one. Final retail kits and prices freeze with E2.5 / cost model sign-off.

Core internals flatlay โ€” Pi 5, cooler, UPS cells, mic array

Included in every BRAIN

Not sold as an upsell โ€” already in the core unit.

  • Raspberry Pi 5 16GB + official Active Cooler
  • Geekworm X1200 UPS + 2ร— 18650 cells (power via X1200 USB-C)
  • Dual M.2 + Hailo-8L (Geekworm X1004 path โ€” watch and talk at once)
  • microSD boot + internal 256GB NVMe on BRAIN (~236GB usable; larger on MAX/OMNI)
  • ReSpeaker XVF3800 USB 4-mic far-field array
  • 5W/4ฮฉ speaker driven by the mic board's onboard amp (mono โ€” keeps echo cancellation)
  • Dual Camera Module 3 eye pods + long CSI FFC + F/B/L/R docks + blank plates
  • Stereo bar path for both-forward software depth (stills / quiet scenes)
  • ~24โ€“30 NeoPixels in bottom U-channel
  • STEMMA / blank bays / rear grommet ready for later kits
SENSE Core flatlay โ€” SHT45, lux sensor, soil probe, STEMMA cables

BRAIN-SENSE Core

Optional plant / environment kit. Plugs into STEMMA ports already on the shell.

  • SHT45 temperature / humidity (or BME280 + pressure)
  • VEML7700 lux sensor
  • STEMMA capacitive soil moisture probe
  • STEMMA QT cable pack (+ Pi I2C adapter if needed)
SENSE Expanded flatlay โ€” COโ‚‚, spectral, and IMU breakouts

BRAIN-SENSE Expanded

Core kit plus denser air and motion sensing.

  • Everything in SENSE Core
  • SCD40 / SCD41 COโ‚‚ sensor
  • AS7341 spectral / color light sensor
  • IMU (motion / orientation)
GPS kit flatlay โ€” circular GNSS puck and cable

BRAIN-GPS

Field and travel geotagging โ€” one GNSS puck on a side cable.

  • BLE or USB GNSS puck
  • Cable / mount as required for the chosen puck
USB Archive flatlay โ€” external SSD enclosure and cable

USB Archive

External archive volume โ€” does not replace internal NVMe.

  • External USB SSD / HDD 1โ€“2TB class
  • Intended for cold archives and media dumps
NoIR kit flatlay โ€” dual NoIR camera modules, IR illuminators, CSI cables

NoIR Kit

Night vision path for OMNI or as an add-on.

  • Camera Module 3 NoIR pods ร—2
  • IR illuminators for the shell / dock layout
  • Compatible CSI cabling for movable docks
Camarray stereo kit flatlay โ€” dual global-shutter cameras and sync board

Motion3D / Camarray

CSI stereo HAT for hardware-synced depth video โ€” not an M.2 module. Included on OMNI; kit for BRAIN/MAX. Research parts about $260; retail not set.

  • Arducam Camarray-class global-shutter stereo kit (AR0234 family, B0492R-class)
  • UC-512-class HAT: GPIO + one CSI port โ€” does not occupy dual-M.2 Hailo/NVMe slots
  • Hardware sync / HAT bundle as specified for Pi 5
  • Mount path for forward stereo bar (~60โ€“120 mm; 80โ€“100 mm typical desk depth)
  • For moving subjects โ€” dual Cam3 alone is software-synced (stills / slow scenes)
Storage upgrade flatlay โ€” larger NVMe module

Higher storage (MAX / OMNI path)

Hailo-8L is already in every BRAIN/MAX/OMNI. This kit is NVMe capacity only. BRAIN-PRO uses USB SSD instead (AI HAT+ 2 owns PCIe).

  • NVMe upgrade sized to the compute tier (1TB / 2TB+)
  • Fits the dual-M.2 slot already on BRAIN / MAX / OMNI
