## Description

#### What is it?

ESP32S3-MINI-1-N4-R2 board

- Stereo TDK ICS 43434 MEMS microphones
- MAX98357A speaker driver and on-board speaker (**very quiet**)
- LiPo charger circuit
- USB-C for power, charging, and programming.
- Button
- 5 on-board WS2812 LEDs around the edge
- GPIOs clearly marked on silkscreen

Speaker is quite quiet. It actually sounds louder if you cover the front of the speaker?! Obviously my plan was this should be louder, but makes for a great board for testing I2S audio. Heence selling cheaply.
