A custom PCB was needed for power management of our LiDAR sensor (Velodyne) and the onboard computer (Gigabyte Brix). The PCB takes the nominal 14.8 V from the battery and steps the voltage down to 12 V for the LiDAR and steps up to 19 V for the computer. We also added an AC/DC adapter to the board for early power-on of the computer using a constant power source to get GPS lock-on, which can take several minutes. LEDs are used to check for battery connection, adapter connection, and voltage regulation to the LiDAR, computer, and powerpath controller.
