In this tutorial, you will learn how to interface the SD Card Module to the Arduino Mega via a Sensor Shield.ДЇirstly, let's take a close look at the SD card connector on the Mega Sensor Shield. Interfacing SD Card Module to Expansion Shield MEGA Sensor Shield V2 for MEGA 2560 Example: It is possible to use +6 volts if ALL the attached devices are the same such as Servos with that rating.Дedicated Connectors (pins left to right, top to bottom, as the above picture) Usually, this is +5V because most external devices require it. Using an external supply allows more current than the Arduino or Mega can supply, such as current for control of many servos or Relays, and other attached devices. External power Ground must also be connected to the blue terminal strip. Jumper off: +5 (or other appropriate voltage) comes from an external supply connected to the blue terminal strip.The jumper on +5 comes from the Arduino.This version has two options of +5V supply to all the 'V' pins: The 'Analog' 3-pin groups still use the Arduino +5V which is better from an electrical noise perspective.

This is good for large numbers of servos etc. It also has an option to power the 'V' pins on all the Digital I/O 3-pin groups from an external power supply instead of the Arduino +5V. This shield also has connectors specifically for some external devices like an SD Card, Radiocommunications (Bluetooth and others). The Arduino MEGA has many more I/O pins (54 Digital pins and 16 Analog pins)than a standard Arduino.
