Neurosity Crown tear-down: from which electronic components is it built from?

Last Updated on September 10, 2024 by pg@petergamma.org

• Neurosity Crown consists of an 8 channel EEG module and a single board computer, and transmission to the single board computer is over WIFI.
• A.J. Keller said the device was developed in Brooklin New York. We suppose it is based on OpenBCI components.
• William Croft said A.J. Keller has left www.openbci.com.
• We suppose the Neurosity Crown uses an ADS1299 EEG chip module.
• Alex Castillo is Co-founder of Neurosity who leads everything software at Neurosity:

• A construction principle of Neurosity is that the EEG module is close to the single board computer, as Alex Castillo explained on YouTube.

Which would mean that the EEG part is not connected to the single board computer over the GPIO pins as it is with PiEEG:

In the Neurosity Notion signal transmission is 250 times a second, we suppose it is WIFI. And EEG data are processed on the headset, as Alex Castillo explains in the following video:

• In the next video we can see a Neurosity Crown tear-down
• Neurosity Crown contains:

• we can see not PiEEG
• we can see no OpenBCI Cyton module
• we can see no OpenBCI WIFI shield
• we can see no Raspberry Pi 4 SBC
• The single board computer they use must be small, we cannot recognize it:

But we suppose it contains:

• A modified OpenBCI Cyton board which has half size of it. One module we see in the video reminds of the OpenBCI Cyton form factor.
• A modified OpenBCI wifi shield which has half size of it. One module reminds of the OpenBCI WIFI shiel form factor.
• A Raspberry Pi zero. And usb connector which we can see could be the one of a Raspberry Pi zero.
