BOARD FEATURES:

We enter in Arduino field 5 years after the design was introduced, and this allowed

us to see and skip all the errors the Arduino inventors did :-)

We had the possibility to read current customer feedback and to implement what

they wanted to see in the original Arduino.

There are few thinks which we made better than the original Arduino design:

1. We allow the board to work at different frequencies with easily exchange of

the quartz crystal.

2. Original Arduino uses linear power supply, this limits the input voltage

range. We designed the power supply to accept power from 9 to 30V DC thus making

possible to take virtually any power supply adapter on the market, also enable

application which are in industrial power supply 24VDC.

3. We carefully selected all components to work reliable in INDUSTIRAL

temperature range -25+85C so the board can be used in INDUSTIRAL applications

while the original design is to Commercial 0-70C operating temperature.

4. The original Arduino design is not good for portable applications as consumes

too much power with the linear vltage regulators, we put ULTRA LOW

POWER voltage regulators and the consumption is only few microamps, which enables

handheld and battery powered applications.

5. We add Li-Ion rechargable battery power supply option with BUILD-IN on

board charger, so when you attach battery it is automatically charged and kept in

this state until the other power source (USB or external adapter) is removed and it

AUTOMATICALLY will power the board - no jumpers, no switches!

6. Our design can work both on 3.3V and on 5V which is selectable with

switch.

7. Our board have UEXT connector which allow many existing modules like

RF, ZIGBEE, GSM, GPS to be connected.

8. Our desing allow RTC - Real Time Clock.

9. We made our design noise immune, there are number of threads on Arduino

forum for problems with the RESET when board works with motors, this is because

Atmel recommendations were omited in the original design, we fixed this.

10. We use separate voltage regulator for the Analog part, which allow the

ADC to be read correctly without the digital noise pickup.

11. Optionally if someone need higher precision and temperature stability in

Analog reading we have provision on the board for Aref preciese source.

12. The LEDs and the BUTTONs are on the edge of the board so there is easy

access even if the boards have shields on them.

13. All components are LOWER than the connectors, so the shields do not interference

with them.
