Highlights

  • 1.working voltage 3.3V/5V is optional. Arduino can only work under 5V, when the moudle is 3.3V, it could not connect with IO jack directly . A voltage convertor is needed --eg. SD card, bluetooth module etc. While the improved one can work with 3.3V ,by sliding the voltage switcher it could connect the 3.3V module directly.
  • 2.More powerfully power supply. Arduino use FT232RL 3.3V as power output, maxium output current is less than 100mA, when there is larger current external module, the power supply is not enough . The improved one use 1117-3.3 as power supply, maxium current is 500mA. Arduino only has 500mA 5V power supply, when it uses external power supply, it can provide 2A 5V power supply.
  • 3.Clearer LED indication. The indicator on the extending board of Arduino will be hidden, could not see the indicator of PWR, TX & RX . The improved one has moved the indicators to the edge of the board , even there is external board , you can see them well.
  • 4.Can reach the RESET button easier. The RESET button of Arduino will be hidden when insert the extending board , and could not reset the main board . The improved one has moved the button on the edge , you can reach it easily.
  • 5.Extended pin. The anolog pin & 3 digital pin has been lead out through normal Electronic blocks / actuator 3pin of Arduino. This makes connecting with many Electronic blocks' sensor /control module and actuator much easier . No need sensor extending board.
  • 6.Wide input voltage. Arduino only support 7-12V input , while it support 7-23V input.
  • 7.More stable AD sampling. The AD circuit of Arduino is too casual ,interference is severe , when use IIC pin to communicate (A4A5), other anolog pins will be effected, could not sampling correctly. This problem will not happen on ACD circuit. When switch the working voltage to 5V ,this board is 100% compatiable with Arduino Duemilanove.
