1.Background
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.
