5. System Control and Ecosystem Access

The CK-RX65N provides a power supply regulator, an on-board debugger, simple I/O (switches and LEDs),
and popular I/O ecosystem connectors. These are all described in detail below.
5.1 Power
The CK-RX65N kit is designed for +5 V operation. An on-board switching voltage regulator (ISL8002IRZ) is
used to convert the 5 V supply to a 3.3 V supply. Also fitted is a low dropout regulator (ISL9008AIECZ-T) to
convert the 3.3 V supply to a 1.8 V supply. The 3.3 V supply is used to power the RX MCU and other
peripheral features as well as the microphones and some of the sensors. The 1.8 V supply is used to power
some of the motion and pressure sensors.
