Absolute Maximum Ratings for Arduino card

Most of the Arduino board use the same working voltage at 5V, and their schematic are almost similar (I mean the pin voltage/current rating design). Because DFRobot's cards use different resistence at somewhere, so it might be a little different for some ratings on different pins. Here are some specification about most of DFRduino controller ratings, just for reference:

• Operating Temperature: -55 - 125℃
• Storage Temperature: -65 - 155℃
• Voltage on any Pin except RESET with respect to Ground: -0.5 - Vcc+0.5V
• Maximum Operating Voltage: 6V
• DC Current per I/O Pin: 40.0 mA
• DC Current Vcc and GND Pins: 200.0 mA
