ESP32-C3 Super Mini

The ESP32-C3 processor is a single-core SoC based on the open-source 32-bit RISC-V architecture.

It has almost the same size as the XIAO ESP32 C3 but comes with an onboard antenna. Caused by this very small antenna the weak WiFi and BLE RF signal strength may limit the usability.
