Today we're excited to announce that Octopus 16 is officially available on Elecrow. High-density, wireless biosignal acquisition just got a whole lot more portable.
16 Channels, No Wires, No Lab
Octopus 16 brings 16-channel biosignal acquisition to the palm of your hand. Built on the Seeed Studio XIAO ESP32-S3, it streams EEG, EMG, and ECG data wirelessly over Bluetooth—no single-board computer or bulky wired setup required.
At its core are Texas Instruments ADS131M08 analog front-ends, delivering high-quality 24-bit biosignal data across all 16 channels.
Why Octopus 16
- 16 full channels for rich spatial coverage in a compact, wearable form factor
- Wireless Bluetooth streaming — pairs like any Bluetooth device
- 24-bit resolution per channel for research-grade signal capture
- Battery-powered operation isolates the device from mains noise
- PiEEG-Server integrated — visualize your data directly in the browser
- PiEEG Cloud compatible — connect right from your browser, zero install
No gel required. No lab required. Just neural data, wirelessly.
Built for Builders
Octopus 16 is ideal for researchers, students, and developers building advanced BCI prototypes, wireless neural-interface applications, and multi-channel embedded setups. Firmware for the XIAO ESP32-S3 flashes in seconds, and the open-source Python SDK includes tools for FFT analysis and real-time signal visualization.
And because Octopus 16 is fully compatible with PiEEG Cloud, you can connect and start streaming straight from your browser over Web Bluetooth—no installation required.
