I have just received my 5 pieces of very cool product based on the ESP32-C6 such as T-QT C6. I never seen on the market for ESP32-C6 something similar such as a small touch panel screen, PMU, etc. in the mini enclose. Notice, that the product description shows the following:
Attention: Currently, ESP32C6 can only be programmed using the Arduino IDE

So, I took this risk for order it anyway, because my development environment is the Microsoft Visual Studio and C# programming, and the result is the following screen snippet:

The above board is running my app such as an IoT Device connected to the Microsoft Azure IoT Central for handling and managing a device telemetry data. It's built using the NanoFramework .NET C# code.

In other words, the T-QT C6 has been flashed with the NanoFramework firmware, connected to the Visual Studio 2022 and using programming technique like at the other projects included its debugging.

Thanks for T-QT C6 team for creating this cool product and I am looking forward for its next version and extensions, for instance, some adapter (stack) to use sensors from the M5Stack product line.

In addition:

Also, why the external pins are not vertically organized in the 2 rows for easy connection, for instance I2C pins such as IO22, IO21, 3.3V, GND (4pins header) which it will allow to use a standard 4pins dupont header to Grove cable.

What was a reason to make a hardwired connector for UART instead of using the standard and flexible configurable connectivity (UART/I2C/GPIO)?
