Several years ago Chinese developers offered us a 32 channel ADS1299 BCI EEG Acquisition Board ESP3 board on Aliexpress for around 1 200 USD.
Then the price for this board slowly increased to about 4 000 USD, until this board disappeared again from Aliexpress.
Now, we are not interested anymore in EEG devices based on the ADS1299 BCI EEG from Texas Instruments.
And we are looking for a printed circuit board for 32 TGAM Modules = 32 x 30 USD = 960 USD.
