Unexpected Maker TinyS3 specs, pinout & datasheets
- 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
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.
- MicroPython
- Supported[3]
- CircuitPython
- Supported[2]
As published by each project, checked weekly. A platform not listed has no published information here, which is not the same as no support.
