Just a question on the I²C clock pins on the A-Star 32U4 Robot Controller SV with Raspberry Pi Bridge.
I would like to use a few I²C sensors on my project but am not certain if the listed SCL/SDA pins are available for 5v A-Star use or reserved for 3.3v Raspberry Pi communication... it would seem the latter:
PD0 3, SCL I²C clock for Raspberry Pi communication
PD1 2, SDA I²C data for Raspberry Pi communication
But the only other SCL/SDA referenced seem to be that actual RasPi ones at GPIO 2 and GPIO 3
