1 Operating voltage 3.3V / 5V optional. Arduino can only work at 5V, 3.3V all often encounter level interface modules,IOport can notbe connected directly.The need forlevel shifting,such asSDcard, Bluetoothmodule. Funduinocan make itworkat 3.3Vviatoggle switch,this time thelevel is3.3VIO portcanworkdirectlywith the3.3V levelmodules.
2 Stronger power. Arduino using FT232RL 3.3V output power, maximum output current is less than 100mA, require large currents encountered peripheral modules will supply shortage. Funduino use 1117-3.3 output 3.3V power supply, the maximum current is 500mA. Arduino 5V power supply only 500mA, while Funduino use an external power supply when the power supply can provide up to 5V 2A.
3 more obvious LED indication. When expansion board plugged it, Arduino LED will be blocked, you can not see PWR, TX and RX indicators. Funduino moved the indicator board edge, even with expansion board can also see the light.
4 is easier to press the reset button. Arduino reset button when the expansion board is inserted will be blocked and can not be reset on the motherboard. Funduino reset button to move the edge of the board, can easily press .
5 Extended 5-pin lead. Arduino analog pins and three digital pins by common electronic building blocks / steering 3PIN interface leads. You can easily connect directly to many electronic building blocks sensor / control module, and steering gear, do not use the sensor expansion board.
6 wide input voltage. Arduino only supports 7-12V input, but Funduino support 7-23V input. |
