MAX86141 Breakout Board for Arduino, Do Pulse Oximetry and Brain FNIRS!
Breakout board for State-of-the-Art Pulse Oximetry and Brain FNIRS. First boards ship early October, right after our HEGduino V2 units to fill all of our current orders.
Features a MAX86141 dual channel 19 bit 4000sps simultaneous sampling ADC, two high sensitivity BPW34S photodiodes, and bright 640nm Red and 940nm Infrared LEDs.
Breadboard-friendly design. Comes with free drivers for Arduino and free software support for brain biofeedback and pulse oximetry.
The last two images of the pulse waveform on this page were taken through our skull, compared to the first image taken on our finger. The signal quality is excellent for FNIRS! Our main goal with this model was to make it the best possible oximeter, powerful enough to accomplish clean signals at depth for FNIRS tasks, where noise has traditionally been a major issue. With the clear pulse/SPO2 signal, it is much easier to validate signal fidelity.
This breakout board is flexible and can be used as a folded finger tip pulse oximeter or a ~1 inch depth-penetrating reflectance oximeter or brain FNIRS device. It is highly durable for general use, easy to use with our free drivers, and is the main ingredient in our HEGduino V2: The Delobotomizer which we use for biofeedback and experimental brain oximetry. We are offering it as a breakout board for all of your creative and research ideas.
Support the future of biofeedback and open source imaging tech by supporting our work! We are dedicated to producing low cost state of the art brain and health tools for the general public to learn and use. Thank you!
