Power supply

This Shield2Go needs to be connected to a 3.3 V DC power supply that provides at least 150 mA. Connect +3.3 V
to pin 7 and ground to pin 6 (GND).
The BGT60LTR11AIP Shield2Go is equipped with a 150 mA Infineon LDO TLS202A1 that provides the necessary
1.5 V for the radar IC, as seen in Figure 16.

Level shifters

The Radar Shield2Go is equipped with 3.3 V to 1.5 V level shifters. The level shifters are responsible for
transforming the voltage signals to 3.3 V. Hence, all inputs/outputs of the Radar Shield2Go work only with 3.3 V
voltage levels. For use with, e.g., 5 V levels, further level shifting is required. The level shifting on the
BGT60LTR11AIP Shield2Go is shown in Figure 17.
