Hi,  
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 the following muscles for 4 fingers?

**Muscle Mapping & Electrode Placement:**

- **Flexor Digitorum Superficialis (FDS):** Detects finger flexion for Braille numbers 1–5 (Forearm – flexor side)
- **Thenar Muscle:** Detects thumb pinch for Braille number 6 (Palm base near thumb)
- **Hypothenar Muscle:** Detects index-thumb pinch for app shortcuts (Palm base near pinky)
- **Extensor Digitorum (ED):** Detects swipe gestures for navigation (Forearm – extensor side)

Also, 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?

Did you have any luck with this?

Also how did you boot up the ESP32 Wireless Shield to Arduino IDE?

Also I don’t think you need 4 sensors, 1 would be enough.

It should be possible from one power source 🙂
