- Standard "Pi / Arduino" SoC-style interfaces including UART, I2C,
SPI, GPIO, PWM, EINT, AC97.
+The "PI / Arduino" style interfaces are provided so as to be pin-comoatibke with the existing "Shield" 3rd party producy markets.

# Interfaces
Much of the advanced section is "under consideration" because there are proprietary firmware issues involved as well as high power consumption and high costs involved. OpenCAPI for example would, in 22nm, at 25 ghz, be an enormous power draw (IBM used 14nm for the POWER9 25ghz SERDES)
