Appendix E. Expansion Headers
The M30280FA MCU on the RZB-CC16C-ZDK target board is housed in an 80-pin QFP package. Pin 1
of the package is identified by a little white circle on the board’s top silkscreen. Connectors J1 to J4,
located around the MCU, provide access to almost all of the MCU’s pins. You can use J1-J4 as test
points to check MCU signals or, by mounting your own headers, connect your own expansion board. The
silkscreen identifying the connectors is at the bottom of the ZDK board. The following table shows the
mapping of J1-J4 pins to MCU pins and signal names.
