- Chip / SoC
- ESP32-C3
- Clock
- 160 MHz
Imported entry: generated from open-source board definitions (platformio, zephyr, circuitpython, micropython), not reviewed by a person. Each fact links to the definition it came from.
Specifications
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?
- Arduino framework
- Supported[1]Arduino framework available through PlatformIO.
