3.3V / 5V FT232RL output, 7V - 23V input Arduino Duemilanove board compatible Freaduino v1

Arduino Duemilanove improve board Freaduino v1.0 compatible


Arduino is an open source code base with the Simple i / o platform, and has used a similar java, C language development environment. So you can quickly use the Arduino language and software such as Flash or Processing ... to make interactive works. Arduino can be used to complete the development of electronic components such as Switch or Sensors or other controller, LED, stepper motor, or other output device. Arduino can also operate as an independent platform to communicate with the software, such as: flash processing Max / MSP VVVV or other interactive software ..., Arduino open-source development IDE interface is based on the principle that allows you to download and use to develop more people amazing interactive work.


Freaduino is ElecFreaks Sutido in the original Arduino Duemilanove (ATmega328P) made some improvements on the basis of fully compatible board. It is fully compatible with Arduino interface and software, so you can directly use all the expansion boards for the Arduino design and software.




Freaduino improvement:
1 Operating voltage 3.3V / 5V optional. Arduino can only work in 5V, 3.3V all levels often encountered in the interface module, IO ports can not be directly connected to the conversion level needs to be done - such as SD Card, Bluetooth module.Iteaduino toggle switch so that it can work at 3.3V, this time the IO port voltage is 3.3V and 3.3V can work with the module level. (Note: 3.3V 16M state of the MCU clock is overclocking, but after the actual test, MCU is stable, safe to use)

2 more power. Arduino using FT232RL 3.3V output supply, the maximum output current of less than 100mA, encountered peripheral modules require high current, it will have enough power. Freaduino use 1117-3.3 output 3.3V power supply, the maximum current of 800mA. Arduino's 5V supply only 500mA, LDO and Freaduino change the original design DCDC, can provide up to 2A of 5V power supply.

3 more visible LED. When the lights Arduino board expansion will be blocked plug, can not see the PWR, TX and RX indicators. Freaduino the edge of the light moved to the board, even if there are expansion boards can also see the light.

4 is easier to press the reset button. Arduino reset button in the expansion board inserted will be blocked and can not be reset on the motherboard. Freaduino reset button to move the edge of the board, can easily click to whenever.

5 Wide input voltage. Arduino supports only 7-12V input, but Freaduino support 7-23V input.
