Bot-Logic Power SupplyThe BOT-LOGIC Shield has an on-board high-efficiency switching power supply, eliminating the need for separate batteries for the Arduino and servos. It can use a 4.5V-20V battery pack, supplying a steady 7.0V into the Arduino Vin pin. This keeps the Arduino running cool while the power supply supplies 7.0V to the Arduino even if battery voltage drops as low as 3.0V. This keeps the Arduino running reliably even when servos are drawing significant power.


1) The 7.0V powers the Arduino, not the servos. Servos get voltage directly from the battery through a fuse. so they need to be rated for the voltage range of the battery you choose to connect to the BOT-LOGIC Shield.

2) The normal Vin connector is blocked by a spade lug connector to prevent connection of a power supply to the power jack on the Arduino. Applying power to  this connector while connected to the BOT-LOGIC Shield could damage the Shield as well as the Arduino. The spade lug is not connected electrically and serves no other function.
