Figure 1-2. Connector P4 Pin Assignments
As connector P1 has more importance to an HC05EVS than to an MMDS05, pin assignments
for connector P1 are in Chapter 3.
To configure your P3EM for use as part of an MMDS05, follow the instructions of Chapter 2.
To configure your P3EM for use as part of an HC05EVS, follow the instructions of Chapter 3.
