I’ve been looking through the Edge schematics and other documents. I’d like to work out which Edge fingers / Edge V pins are 3.3V, which are 1.8V and which are the weird 3.0V ones. This isn’t documented anywhere as far as I can see, although the schematic shows clearly which SoC lines each finger/pin connects to.
Is there a good place to look to get a list of which RK3399 GPIO/SPI/I2C/etc. lines are which voltage? I assumed I could find this info somewhere in the RK3399 data sheet or TRM, but I couldn’t locate it when I browsed through.
