Hardware information and current voltage levels
The next block of commands prints information of the manufacturer, hardware and firmware versions, and battery levels. The following relates to the output:
- Battery voltage is the same as before. The measurement gives a slightly different value, 9.294V, and it is OK.
- 5V voltage is that of the power supply to the Raspberry Pi through its GPIO. GoPiGo red board has a power regulator that transforms the 9V raw input to a regulated 5V. If the batteries are properly charged, this value should be very close to 5V as shown here:
