From the esp32-c3 datasheet: 'ESP32-C3 has two UART interfaces, i.e. UART0 and UART1'

Note that in the ESP32 series, a lot of peripherals don't have dedicated pins (even if some have default pins) and the same goes for UART1. You can re-route the UART signals to any available GPIO using the GPIO matrix.
