5.2.1 COM Express® Module Connector Connectors J1 and J2
The pinout of the COM-Express® connectors on the COME-QEC-1, the COMe-bP5020 and the COMe-cP2020 boards are specifically
defined for usage with Freescale® QorIQ® CPUs. Steering member for this definition was the CPU manufacturer Freescale®. The
COM-Express® interface is based on two connectors with two rows (Rows A/B and Rows C/D) with 440 pins total (220 pins for
each of the two connectors). The pinouts for these two connectors are as follows
