Device quick connect

[Duhjoker]

Hi guys

I'm working on an all in one gaming project that utilizes most arduino driven boards. I'm in the process of adding and improving ESP32 libraries but I had a question about device connections. Is there a universal way of connecting extra devices to the boards? Something like I2c?

I thought it might be a good idea to add a quick connect to the system so users can use my device any way they want to and not limit it to just game playing.

I2C, or SPI, or UART.

Possibly seedstudio grove style (jst?) connectors
