Customer #1261426 on DEV-21265 - MyoWare 2.0 Muscle SensorCustomer #1261426urn:uuid:9c0bf7dd-7c29-6935-105e-c5a566e659ce2023-11-08T20:27:00-07:00<p>Hi, I wanted to confirm. The Instrumentation amplifier and the bandpass filters are included in the module. Is that right? Or do we need to create this circuitry by ourselves? Thanks</p>

Sorry, the product is patent protected. To prevent counterfeit boards, the Eagle design files and GitHub hardware repository are not shared for boards in the MyoWare 2.0 ecosystem.</p><p>However, there is some information in the block diagrams. If you have not checked it out, be sure to look in the <a href="https://learn.sparkfun.com/tutorials/getting-started-with-the-myoware-20-muscle-sensor-ecosystem/myoware-20-muscle-sensor" rel="nofollow">Getting Started with the MyoWare® 2.0 Muscle Sensor Ecosystem: MyoWare 2.0 Muscle Sensor</a> and <a href="https://cdn.sparkfun.com/assets/learn_tutorials/1/9/5/6/MyoWare_v2_AdvancedGuide-Updated.pdf" rel="nofollow">MyoWare Advanced Guide</a>.
