ok, I added a secret port to my pcb that plays a song :] you cant see it from here. (sadly I could not install a headphone port)

This, but also don't forget that I2C is the JSON of serial interfaces.
UART is to engineers what CSV is to science researchers. Old school, tried and true, yet complete garbage in terms of extensibility and portability.

Sniff I2C data up to 500kHz with the latest Bus Pirate firmware. The pico-i2c-sniffer project uses all four state machines of an RP2040 PIO to spy on I2C bus traffic. Useful for reverse engineering, debugging, and long duration event logging.

I did a development exercise a 15 months ago where I created a series of I2C client devices (formerly known as I2C slaves) using the ATtiny1616.
In this video, all 9 PCBs are I2C clients. The host (aka master) device was an ESP32 board running CircuitPython.
