Kits

Expansion kits for sense, GPS, archive, night vision, and acceleration. Far-field voice and dual movable face cameras are already in every BRAIN โ€” kits do not re-sell those as upsells.

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)
  • microSD boot + internal NVMe (tier-dependent size)
  • 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

Upgrade for hardware-synced stereo depth video โ€” included on OMNI; kit for PRO/MAX.

  • Arducam Camarray-class global-shutter stereo kit (AR0234 family)
  • Hardware sync / HAT bundle as specified for Pi 5
  • Mount path for forward stereo bar or docked pair
  • For moving subjects โ€” dual Cam3 alone is software-synced (stills / slow scenes)
Accelerator kit flatlay โ€” M.2 NPU module, dual-M.2 board, NVMe

Accelerator (PRO / MAX / OMNI path)

Optional NPU when real-time vision acceleration is required.

  • Hailo-8L / AI HAT+ class accelerator (or AI HAT+ 2)
  • Dual-M.2 board so NVMe and accelerator coexist
  • NVMe upgrade sized to the compute tier (512GB / 1TB+)
