ماژول WiFi و بلوتوث ESP32-C3 Super Mini

When using daughterboards, avoid covering the ceramic antenna with any components such as PCBs, metal, or plastic, as this could interfere with the signal.

GPIO12 to GPIO17 are not exposed because they are used internally for the 4MB Flash memory.

The ESP32-C3-Mini does not use a USB to UART bridge chip. When flashing firmware, you need to hold the BOOT button (connected to GPIO9) while connecting the board via the Type-C USB cable. This puts the device into the download mode necessary for flashing firmware.

The “TX” and “RX” markings on the board indicate the default UART0 pins, where TX is connected to GPIO21 and RX to GPIO20​
