About this board

The postage-stamp C3 board that turns up in every parts-bin project — same single-core RISC-V ESP32-C3 as the DevKit, sixteen pins, and almost no board around the chip.

Its inputs are driven by the analog engine like the rest of the catalog, so a switch or divider wired to a GPIO reads the voltage the circuit actually produces rather than an idealised level — see analog simulation.

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