Important features of Raspberry Pi 3 Model B

The following are the important features:

  • Power:
    • Raspberry Pi is powered by a +5.0V micro USB supply
    • A 2.5 ampere power supply works well to power Pi and it uses a maximum of 1 amp
    • GPIO pins can draw 50 mA of current in total, distributed across all pins where each pin can draw 16 mA
    • The HDMI port uses a 50 mA current, whereas the camera module draws a 250 mA current
    • A USB-based mouse and keyboard can use 100 mA to 1000 mA current

The host system doesn't have diode protection, which means it backfeeds the power to Pi (gives power to Pi). This power that is backfed to Pi bypasses the voltage protection, causing damage to Pi.
  • USB:
    • Raspberry Pi 3 Model B is equipped with four USB 2.0 ports. These...
