Figure 1-2. Connectors P4 and P5 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 D32EM for use as part of an MMDS05, follow the instructions of
Chapter 2. To configure your D32EM for use as part of an HC05EVS, follow the
instructions of Chapter 3.
