What is Elata EEG?

Elata EEG is an open-source electroencephalography platform built around a Raspberry Pi 5 and the Texas Instruments ADS1299 analog front-end. The goal is to democratize EEG hardware with a fully open, right-to-repair design that any lab or hacker can build, modify, and extend. The system supports 8+ channels of 24-bit EEG at research-grade resolution, with real-time streaming, a plugin-based DSP pipeline, and a browser-based kiosk UI.

Hardware

Component	Details
Controller	Raspberry Pi 5 (quad-core Arm Cortex, 40-pin GPIO)
ADC	TI ADS1299 EEGFE: 8-channel, 24-bit analog front-end via SPI
Electrodes	Wet Ag/AgCl or gold-cup with conductive paste (e.g. Ten20)
Display	5-inch or 7-inch HDMI touchscreen (optional)
Cables	Dupont jumpers (2.54 mm), optional shielding / ferrite beads

Two board configurations are supported:

V1: Single ADS1299 EVM (8 channels)
V2: Four synchronized ADS1299 EVMs with shared clock and SPI (32 channels)

Software Stack

Layer	Technology
OS	Raspberry Pi OS (Debian)
Firmware / Backend	Rust workspace: `sensors`, `boards`, `pipeline`, `daemon` crates
Frontend	Next.js kiosk with WebSocket data streaming
Hardware Interface	`rppal` crate (GPIO / SPI / I2C)
Plugin System	Event-driven DSP plugins on a shared `EventBus`
License	GPLv3 (strong copyleft)

Quickstart

git clone https://github.com/Elata-Biosciences/elata-eeg
cd elata-eeg
bash scripts/install.sh

The install script handles system dependencies (Rust, Node.js, Chromium), builds all crates and the kiosk, configures systemd services for the daemon and kiosk, sets up auto-login and kiosk mode, and reboots when complete.

Development Mode

# Stop kiosk mode
bash scripts/stop.sh

# Terminal 1: daemon (from repo root)
cargo run --bin eeg_daemon -- --mock   # --mock for testing without hardware

# Terminal 2: kiosk
cd kiosk && npm run dev

The kiosk UI is available at http://localhost:3000. The WebSocket data endpoint runs at ws://localhost:9000/ws/data.
