AI Thinker ESP32-CAM specs, pinout & datasheets

Microcontroller board · Ai-Thinker

Chip / SoC
ESP32
Clock
240 MHz

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

Specifications

3 specs
Chip / SoC
ESP32[1]
Clock
240 MHz[1]
Upload limits
4 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.
CircuitPython
Supported[3]
Zephyr RTOS
Supported[2]
ESP-IDF
Supported[1]

As published by each project, checked weekly. A platform not listed has no published information here, which is not the same as no support.
