HEGduino 2.0: "The Brain Pulse-Oximeter" AKA "The Delobotomizer"

Here comes affordable, medical-grade Hemoencephalography! We're proud to announce the evolution of our HEGduino kits into a fully fledged device for the medical and enthusiast community alike.


Specs: *These Specifications are Subject to Improvement*

- 3200sps @ 19 bits ADC built for medical pulse oximetry.

- 50mA-200mA adjustible Red and IR LEDs, high sensitivity photodiode.

- 32bit, 4MB, 240MHz dual-core ESP32 microcontroller with rechargable battery support.

- WiFi, BT/BLE, and USB connectivity.

- Fully customizable firmware via Arduino and Espressif.

- Free IoT software and tools to use your HEG on any device with no installs.

Our 2.0 device will be capable of extremely high precision brain pulse oximetry at state-of-the-art speeds. It may even enable measurement of brain waves in your cerebral fluid! We're still testing, but we're convinced we can create a new era of biofeedback thanks to your support!


Expect developer kits to ship before August 2020! These will be considerably nicer than our 1.0 kits as we're touching on every detail to give this a more commercial flair. We'll keep you on a mailing list with periodic updates on our progress. We're targeting a commercial release by the end of 2020 or early 2021. This is early adopter pricing to help support further development.


You will receive:

1 HEGduino 2.0 developer kit (assembled and tested)

1 LiPo Battery

1 USB Cord

1 Custom Headband with industrial design

Free software and support!
