External debug header
In addition to the onboard OpenSDA interface, the R41Z evaluation board supports the use of
external debuggers. A standard 10-pin SWD/JTAG header is provided with the following
pinout to the target R41Z module:

Peripherals
The R41Z evaluation board includes a set of onboard peripherals and a set of Arduino style
headers that allow for additional peripherals of the user’s choice to be added in the form of
expansion shields. These headers share I/O connections to the R41Z module with the existing
onboard peripherals. If an on-board peripheral will interfere with the operation of a shield,
jumpers can be used to disconnect the on-board device.
