ESP32
From dankwiki
A series of 32-bit microcontroller unit from Espressif, the successor to their ESP8266.
ESP32-S3
The ESP32-S3 is a fantastic little update to the classic ESP32. Some notes:
- Voltage on GPIO47 and GPIO48 is only 1.8 (VSPI), unlike the other pins (3.3, VDD).
- There are no default I2C pins. All GPIOs can be used with either of the two controllers with no penalty.
