For closure to this thread, I did send it back and received a full refund! Thank you for all the help here. I raised some small funds to buy a new 16-channel system and I'm sure I'll be back with more questions. Thanks, again!

@wjcroft I measured GND and VDD on the same J3 and read 3.33v. So it sounds like the ADS chip is faulty.

Hi. One of the research assistants in my lab was doing that testing and posting here today. I just checked with him, and he said he used both the AA back and Lithium cell batteries for the testing. He got the same answer with both types of batter…

@wjcroft Found the following voltages: J3 to AVDD : 2.52 v (should be 3.3) AVDD to AGND: -2.52 v (should be + 2.5) AGND to AVSS: -2.52 v

@wjcroft here is the serial monitor dump mentioned above. Looking into the voltage readings now. OpenBCI V3 8-16 channel On Board ADS1299 Device ID: 0x00 LIS3DH Device ID: 0x33 Firmware: v3.1.2 $$$ Board ADS Registers ADS_ID, 00, 00, 0, 0…

@retuitut Will do. Thank you for your input and concern, too!

Understood. Before graduate school, I worked at a company that fixed EEG systems. I have more soldering experience than I ever wanted.

Thank you for the helpful information William. I'll try those things when I get back to the lab. @retiutut. Indeed, we plan to send it back if it does not work. Once our lab gets more funding, which should be soon, we'll be able to buy a new un…

Hi William. I flashed the Cyton board to 3.1.2. When connecting to the dongle, I still get the same issue - accelerometer data streams just fine but there is no EEG stream. I also tried updating the wifi shield and connecting that way (both via w…

Thank you for the help! I'll try flashing the memory and will let you know how it goes. Fingers crossed.

Thank you for the kind words, William. I feel lucky to do my research! I'm happy to chat anytime about ultrasound neuromodulation or technoboosts for mindfulness. And thanks for your input. I'm a big fan of the Open BCI project and was happy to…
