Taurus Brain Wave Sensor Module

Today, I would like to introduce the Taurus brain wave module developed by our company. (Wuxi Sichiray Co.,Ltd)

Due to the price and supply problems of Neurosky's TGAM chip, we have carried out research and development and improvement on the basis of TGAM.

With the efforts of more than two years, the new brain wave module is coming soon.

At present, brain wave sensor modules are used more and more widely in China, among which the TGAM chip of American Neurosky company is the most popular, However, due to the high price and insufficient supply of TGAM chips, the domestic brainwave research and development road is limited, so our company (Wuxi Sichiray Technology Co., Ltd.) choose to independently develop this Taurus brainwave module. After more than 4 years of research and development cycle and more than 10 optimization and upgrading, Taurus EEG module has finally been successfully launched.

Stable supply, better price, better performance...

The Taurus EEG sensor module is a module designed for the consumer electronics market to collect single-channel EEG signals. The module integrates analog front-end acquisition and data processing, and can directly output brainwave spectrum, original brainwave signal and two indicators of concentration and relaxation. The module integrates hardware filtering and software filtering, and integrates a 50HZ notch filter, which can filter out environmental interference and improve signal quality. The module is compatible with dry and wet electrodes and is easy to wear. The module adopts serial communication, which can be easily integrated into other devices to assist in the development.

The module adopts serial communication mode, the baud rate is 9600 and 115200, the module outputs α, β and other brain wave band data and attention, relaxation data at 9600 baud rate, and sends the original brain wave signal at 115200 baud rate.

• Integrated hardware filtering and software filtering, strong anti-interference ability.
• The module uses a 32-bit processing chip, with fast operation speed and powerful performance.
• The module integrates the analog front end and ADC to output digital signals directly, which reduces the difficulty of use.
