2 Hardware modifications
This section highlights some of the changes required to be made to the hardware before interfacing the radar
baseboard XMC4700 with other Arduino shields.
2.1

Removal of resistors

2
If I C communication is intended to be used as the interface to the target Arduino shield, remove the following
resistors (Figure 3): R70, R71, R73, R74, R77 and R80.

2.2

Selection of IOREF

XMC4700 operates in the 3.3 V domain. Depending on the target Arduino shield, the IOREF can be configured as
5 V or 3.3 V via a jumper on P2 (Figure 4).
To select 3.3 V as IOREF, short pins 1 and 2 of P2.
To select 5 V as IOREF, short pins 2 and 3 of P2.
