- gk: This is the main board for the gkv4 and includes the high speed components. It is implemented as a 6 layer board with impedance control requirements specified in the PCBnew file. - pmic: This is a standalone 1 inch square board that contains the STPMIC25 power management chip and associated passive components. It is implemented as a 4 layer board and additionally provided as a panelized board. It is mounted using LGA/castellated holes onto the main board. - controls: This is a daughter board…
