# rp2040-rx
|
|
|
|
This is a sample project for receiving audio data using [RP2040](https://www.espressif.com/en/products/socs/esp32) microcontroller.
|
|
The chip has a built-in 12-bit ADC which is used to process the analog audio from the external microphone module in real-time.
|
|
|
|
## Setup
|
|
|
|
- Raspberry Pi Pico (or other RP2040 board)
|
|
- Microphone, tested with the following, but others could be also supported:
|
|
- Analog:
|
|
- MAX9814
|
|
- KY-037
|
|
- KY-038
|
|
- WS Sound sensor
