3.1 Power Supply Circuit

The power supply circuit is depicted in Section 3.1, which provides 5V power rail to encoder circuit and 3.3V power rail to MSPM0C1104. The circuit utilizes two fixed-output LDO, leading to reduced noise and a stable output and two LED lights to indicate the normal operation of the power supply rail.
