TGAM EEG Module 2.9A EEG Signal Conversion Module Support for Matlab/Python/Unity/Labview Development Platforms

Differences:
- The TGAM module versions are divided into 2.8 and 2.9A. 2.9A is a new version, and both versions have the same functions. Testing has found that 2.9A has slightly changed hardware compared to 2.8, upgraded software, faster transmission speed, and more stability. Developers can use both versions and choose according to their own needs.

Introduction:
- TGAM is the core of EEG sensing technology, which uses dry electrodes to read human brain signals, filters out surrounding noise and electrical interference, and converts the detected EEG signals into digital signals.
- The TGAM module includes a TGAT chip, which is a highly integrated single-chip EEG sensor that can output three eSense parameters for Neurosky, perform analog-to-digital conversion, detect abnormal states of poor contact, filter out eye electrical noise and 50/60Hz AC interference.
- It can directly connect to dry contact points, unlike traditional medical wet sensors that require conductive adhesive for use.
- A single EEG channel has three contact points: EEG (EEG acquisition point), REF (reference point), GND (ground point).
- If the contact point does not collect EEG signals for four consecutive seconds or receives poor EEG signals for seven consecutive seconds after power on, this smart module will issue a warning of signal difference through "signal quality strength" to remind the user to adjust the sensor.
- Advanced noise filtering technology that can resist various interferences in the environment of daily life.
- Low energy consumption, battery powered devices suitable for portable consumer products.
- The maximum consumption under 3.3V power supply is 15mA.
- The raw EEG data is measured at 512Hz output.

Original EEG Signal:
- Process and output alpha, beta and other EEG band data.
- Process and output eSense focus and relaxation indices of patented technology for Neurosky, as well as other data for future development.
- The embedded signal quality analysis function can warn of abnormal states such as poor contact or complete lack of contact.
- Blink detection.
