Hello all, I am currently working on a research project focused on EMG-based finger reading and am looking to read data from 4 muscle sensors. I am considering purchasing 1 MyoWare 2.0 Wireless Shield DEV-23387 along with 4 MyoWare 2.0 muscle sensors .Would this setup be sufficient for my project, where I need to capture muscle data from 4 fingers? Do I need additional products?
is it possible to power both the 4 MyoWare 2.0 muscle sensors and the ESP32 using a a single MyoWare 2.0 Wireless Shield DEV-23387 or do I need separate setup for the power (e.g., LiPo battery with boost converter to step up to 5V)? would it be sufficient to get the readings for all 4 fingers simultaneously?
I needed the suggestion ASAP due to some shipping issue. Can a technical team member help?
The short answer is no, or you’d need 4x wireless shields (one for each muscle sensor)
But! We have this Getting Started with the MyoWare® 2.0 Muscle Sensor Ecosystem - SparkFun Learn which allows up to 6x muscle sensors that I think you should take a look at 
You’d need a board with an arduino footprint, but that’s easy enough
Thanks Russell. I think I found the right setup for my myoware sensors from the sparkfun video (attached). I need to know if I use 4 batteries with 3.7V 40mAh for 4 muscle sensors just like the video, will it power all the muscle sensors? What about the ESP32? Do I need a separate 5V supply? ESP32 will be connected wirelessly to the computer. Is there a better option to power everything?
Yes, with the caveat that those are not 40mAh, they appear to be these Amazon.com (but yes, as demonstrated in the video it can provide enough power…if you run out you can always just use a battery bank separate for the esp32)
Also, 1.2 volts, not 3.7.
