DCDC power supply allows power supply voltage from 9 to 30V DC thus making it possible to take virtually any power supply adapter on the market, and enable applications which are in the industrial power supply 24VDC.
Carefully selected, all of the components work reliably in the INDUSTIRAL temperature range -25+85C so the board can be used in INDUSTIRAL applications.
ULTRA LOW POWER voltage regulators and the consumption is only few microamps, which enables hand-held and battery powered applications.
Li-Ion rechargeable battery power supply option with a BUILD-IN on board charger, so that when you attach a battery, it is automatically charged and kept in this state until the other power source (USB or external adapter) is removed and then it will AUTOMATICALLY power the board - no jumpers, no switches!
UEXT connector which allow many existing modules like RF, ZIGBEE, GSM, GPS to be connected
RTC - Real Time Clock.
NOISE IMMUNE design.
Optionally if someone needs higher precision and temperature stability in Analog reading, we have provided an Aref precise source.
The LEDs and the BUTTONs are on the edge of the board so that they can be easily accessed even if the boards have shields on them
All of the components are LOWER than the connectors, so that the shields do not interfere with them
A Mini USB connector is used, which is common and is used in most cell phones, so you do not have to buy other cables
The original Arduino design had a flaw and the connectors were not spaced at 0.1". This makes perfo board use impossible, so to keep the compatibility we have the same spacing but we added next to it a connector on 0.1" which customers can use with perforated boards
All signals on the connectors are printed on the top and the bottom of the board, so when you check with probe you will know exactly which port you are measuring
4 mount holes make board attachment easier
miniICSP connector 0.05"step - if you do not want to use Pinguino IDE and want to program this board with PIC-KIT3 you should use also PIC-ICSP convertor board, same applies for Microchip programmers.
