2.10 GPIO Header

i.MX 8M Mini SODIMM carrier board supports another 20pin Header (J16) for providing additional GPIO pins from the i.MX
8M Mini CPU. 4 GPIOs,SAI1 signals,ECSPI interface signals pins SODIMM Edge is directly connected to this GPIO Header.This
GPIO Header (J16) is physically located at the top of the board as shown below.
