XIAO ESP32-C3

The board as it appears on the Velxio canvas, with its full pin map read live from the simulator (regenerated by scripts/gen-boards.mjs, so it always matches what you can wire).

XIAO ESP32-C3 board

Family: ESP32-S3 and ESP32-C3 · Languages: Arduino C++, MicroPython, ESP-IDF

Seeed’s tiny C3 — the same single-core RISC-V chip as the C3 DevKit, in the XIAO footprint with a much smaller pin set. Sketches port straight across as long as the GPIO numbers they use exist here; the map below is the authority.

No separate starter: open New ESP32-C3 project and swap the board, or place it from Add Component.
