If you want to learn basic KiCad design going from schematic to PCB and make production ready files then have a look on this video. This design is based on the LM555 timer at will let you blink a LED with a frequency that can be adjusted by the trimmer.
The blink rate is between 1.3 to 10.2 Hz
The dutycycle is between 52.2 to 66.7 %
The board is a simple 2 layer board measuring only 40x30mm and there are only used THT.

The ESP32-C6-WROOM-1 module is a multiprotocol powerhouse, designed specifically for the next generation of smart home and IoT interoperability.
It supports the following wireless protocols:
* Wi-Fi 6 (802.11ax): Operates on the 2.4 GHz band. It includes advanced features like TWT (Target Wake Time) for extreme power saving and OFDMA for better efficiency in crowded networks. It is fully backward compatible with 802.11b/g/n.
* Bluetooth 5 (LE): Certified for Bluetooth 5.3, supporting long-range operation (Coded PHY), high-speed (2 Mbps PHY), and Bluetooth Mesh. Note that it does not support Bluetooth Classic.
* IEEE 802.15.4: This hardware foundation enables two key low-power mesh protocols:
** Zigbee 3.0: Ideal for industrial and home automation.
** Thread 1.3: The primary transport layer for the Matter smart home standard.
* Matter: While Matter is an application layer rather than a radio protocol, the module is specifically marketed for building Matter-compliant devices over both Wi-Fi and Thread.
* ESP-NOW: A proprietary, connectionless protocol from Espressif that allows for direct, low-latency communication between ESP devices without a router.
