Arduino Nano ESP32 specs, pinout & datasheets

Microcontroller board · Arduino

Chip / SoC
ESP32-S3
Clock
240 MHz

Imported entry: generated from open-source board definitions (platformio, circuitpython, micropython), not reviewed by a person. Each fact links to the definition it came from.

Specifications

3 specs
Chip / SoC
ESP32-S3[1]
Clock
240 MHz[1]
Upload limits
16 MB flash, 320 KB RAM[1]

Upload limits are what a sketch or firmware may use after the bootloader, as the build tools enforce them, not the chip’s full memory.

Can I still use it?

4 platforms
Arduino framework
Supported[1]Arduino framework available through PlatformIO.
