IDE burning option board type: the Arduino Duemilanove w/atmega328

Arduino is a piece of USB interface based on open source Simple I/O interface board (including 12 channel digital GPIO, 4 channel PWM output, 6-8 channel 10 bit ADC input channels), and have used similar to Java, C language IDE integrated development environment. Allows you to quickly use the Arduino language and Flash or Processing... Software, such as interactive work.

Arduino can use developed electronic components such as Switch sensors or other controller, LED, stepper motor or other output device. Arduino can also become a can operate independently and software interface of the ditch, for example: flash processing Max/MSP VVVV or other interactive software... . Arduino IDE interface based on open source code, allows you to free download to use to develop more amazing works of interaction.

It has its own culture, a kind of stands for open source culture, idea behind in its culture, is the essence of science and technology and the art of interactive media. For a robot lovers, especially for the lack of knowledge, the friend that do not control, the Arduino can solve your problem, it is a very easy to master control platform.

Iteaduino is ITead Sutido in the original Arduino Duemilanove (ATmega328P) based on some improvements and become fully compatible with the board. It is fully compatible with the Arduino interface and software, so all can be used directly for the Arduino extension plate and the software design.

Teaduino improvement:

1. The working voltage of 3.3 V / 5 V is optional. Arduino can only work in 5 V, all have a lot of time 3.3 V level interface module, IO mouth can not be directly connected, you need to do to level transformation - such as SD card, bluetooth module and so on. Iteaduino can toggle switch to make it work in 3.3 V, then IO mouth level of 3.3 V can directly work with 3.3 V level module.

2. The stronger power. Arduino using FT232RL 3.3 V output power supply, the maximum output current is less than 100 ma, need large current of a peripheral modules, power supply shortage. Iteaduino USES 1117-3.3-3.3 V power supply output, the maximum current of 500 ma. Arduino provide only 500 ma 5 v power supply, and Iteaduino use external power supply, can provide at most 2 a 5 v power supply.

3. The more obvious the LED indicator. Arduino obscured when have expanded plate with the indicator of live, can't see PWRS, TX and RX indicator light. Iteaduino move the light to plate edge, even with the extension board can also see the light.

4. The expansion of the pin leads. Arduino pins and 3 according to the general electronic digital pin blocks/steering gear 3 pin interface leads. Can be connected directly to a lot of electronic building blocks sensor/control module, as well as steering gear, do not need to use the sensor expansion board.

5. Wide input voltage. Arduino support only 7-12 v input, but iteaduino support 7-23 v input.

6. AD sampling is more stable. Arduino AD go line may be arbitrary, the interference is serious, when using IIC foot communications (A4A5), other analog pins will be affected, cannot correct sampling. This kind of problem will not appear in Iteaduino ACD line.



When the work voltage to 5 v the board with the Arduino Duemilanove 100% compatible.

We all kinds of electronic building blocks module provides a number of compatible, including various types of sensors, relay control blocks etc.


  1. External power input used DCDC circuit to replace the Arduino MEGA2560 ", reduced the waste heat loss of electricity, energy saving more than 50%! Input range is wider, from 7 to 27 v, maximum output current is 2 a. To note here, because ATmega2560 itself is ma level of power consumption, our version 1.1 adds a 500 ma PTC (self recovery fuse) is on the board, current 500 ma will disconnect, after powrefailure automatic reply, so current can not be dragged into 2 a, if you need the application of external received 2 a, is the need to bend down - find a zero resistance r, dropped the PTC short circuit. PTC? Beside the switch.. Find their own

    2. 5 V / 3.3 V switch. Find a is Iteaduino series standard, can choose to compatible with 3.3 V IO operation level, external equipment, such or 3.3 V microcontroller development board communications need not do level conversion - such a practical improvement, the Arduino team how to don't update to the new version? Ha ha, because if you go to the chip manual, actually ATMEL is not recommended for 3.3 V to run 16 m drop. Foreigners is rigorous, think the have to design the chip manual, standard 5 v 16 m. But actually AVR design margin is enough, early in the manual 3.3 V is 16 m in the safety area, can use - of course, if you don't trust, then honestly work under 5 V.

    3. Provides multiple electronic building block interface, convenient and quick access to all types of electronic building blocks module, add a button, the LED display or relay switch function. Electronic building blocks (don't know what is ITEAD? You're OUT! Let the outside world a circuit with spell blocks as simple, as long as a line, an electronic building modules, plug-in and Play! ITEAD provides much 29 kinds of all kinds of electronic building blocks, including from the LED, relay, button to all kinds of sensors, very convenient to all kinds of function you need to add to the Arduino)

    5. The Arduino pins for because of the negligence of the original designer (he acknowledged in the Forum), is not compatible with all 2.54 mm spacing, lead to universal board/hole hole plate - can not connect directly to D7 D8 that spacing, the designer was brain-dead incredibly not standard 2.54 spacing, this creates a Arduino standard later. This is very inconvenient, so we will in the side pin leads to the welding plate, this part is standard 2.54 spacing, you can weld line after needle directly welded to the common universal plate/hole hole on the board!
