So my project is nearing rev2 - hopefuly the last prototype. Thankfuly all issues have been ironed out with REV1.0 pcb...
I have a load of WS2812 inside the main unit, and I break out to another WS2812 strip outside of the main unit. I am also thinking about adding an i2c line to have a small OLED with this strip.
I am thinking about what kind of connector to use....
so the lines would be:
WS2812 DATA
GND
+5V
i2c SCL
i2c SDA
3v3 - this could be ommitted and I use the 5v line for the WS2812.
I had thought about a jack socket, but there will be lots of these for audio. I want to keep connector styles unique
Same goes for 5 pin DIN socket but there are already MIDI sockets....
other sockets already in place are USB A and B
ethernet
d-sub 15 x3 rows for VGA
A mini DIN maybe?
The cable length will be short no more than 50cm, so I dont see an issue for i2c line. Crosstalk maybe an issue?
Suggestions welcome
