# rp2040-rx
WIP in progress
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
## Pinout
### Analog Microphone
| MCU | Mic |
| ------- | --------- |
| GND | GND |
| 3.3V | VCC / VDD |
| GPIO 26 | Out |
