Description:
1. Operating voltage 3.3V / 5V optional. Arduino can only work at 5V, so often encountered 3.3V level interface modules, IO ports can not be directly connected to the level needed to make the conversion. Such as SD card, Bluetooth module. Funduino can make it work at 3.3V via toggle switch, this time the level is 3.3V IO port can work directly with the 3.3V level modules.
2. More power. Arduino using FT232RL 3.3V output power, maxi sors / control modules, and steering gear, do not need to use the sensor expansion board.
3. More obvious LED indication. Arduino lights when there is an expansion board will be blocked when plugged in, you can not see PWR, TX and RX indicators. Funduino moved the indicat or to 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 move to the edge of the board, can easily press.
5. Extended pin leads. Arduino analog pins and three digital pins leads by common electronic building blocks / steering 3PIN interface. You can easily connect directly to many electronic building blocks.
6. Wide input voltage. Arduino only supports 7-12V input, but Funduino support 7-23V input.
7. More stable AD sampling. Arduino AD traces is more casual, and serious interference, when using IIC foot communications (A4A5), other analog pin will receive influence, not sampled correctly. This problem does not occur in Funduino the ACD line.
