Microphone
About the Microphone PCB
Microphone is an open source PCB design by aezrapour, published on GitHub under the MIT license. It is a 2-layer board measuring 5.5 × 6.1 mm, with 6 components from 6 distinct parts.
Other key parts include the AP130-33RG-7. By type, the board carries 2 capacitors, 2 resistors, 1 IC and 1 connector.
From the project
1. Python Websocket server 2. Flutter Application 3. Esp32 firmware 4. Mobile hotspot or wifi connection to allow communication between flutter app and esp32

1. Launch python env 2. use rinsightwebsocketserverv2`:
This should start the websocket server on your machine on port 8887
