8 xx /COMM Expansion Connectors
MBX series embedded controllers support EBX form factor expansion
modules such as PC/104, PC/104-Plus, and 8xx/COMM modules. On
MBX860 boards, the 860/COMM expansion connector (P1), a 144-pin
high-density socket, provides the electrical connection for expansion
modules. On MBX821 boards, the 821/COMM expansion connector (P1)
performs a similar function. The pin assignments are listed in the following
two tables.
