BOARD FEATURES:
We entered the Arduino/MAPLE field 5 years after the design was introduced, and
this allowed us to see and resolve some of (what we consider) errors made by the

Arduino inventors :-)
We had the possibility to read current customer feedback and to implement what
they wanted to see in the original Arduino.

1.
Original Arduino/MAPLE 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 it possible to take virtually any power supply adapter on the market,

also enable application which are in industrial power supply 24VDC.
2.
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.
3.
The original Arduino/MAPLE design is not very reliable for portable ap-
plications as consumes it too much power with the linear voltage regulators, we put
ULTRA LOW POWER voltage regulators and the consumption is only few mi-
croampers, which enables handheld and battery powered applications.
croampers, which enables handheld and battery powered applications.
4.
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
this state until the other power source (USB or external adapter) is removed and it
AUTOMATICALLY will power the board - no jumpers, no switches!
5.
Our board has UEXT connector which allows many existing modules like
RF, ZIGBEE, GSM, GPS to be connected.
6.
6.
Our board has SD-MMC card
7.
Our board has CAN driver on board
8.
Our design allows RTC - Real Time Clock.
9.
We made our design noise immune.
10.
We use separate voltage regulator for the Analog part, which allows the
ADC to be read correctly without the digital noise pickup.
11.
11.
Optionally if someone needs higher precision and temperature stability in
Analog reading we have provided place on the board for Aref precise source.
12.
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.
13.
All components are LOWER than the connectors, so the shields do not in-
terfere with them.
14.
14.
mini USB connector is used which is common and used in most cell phones,
so you do not have to buy other cables
15.
15.
Original Arduino design had a flaw and the connectors were not spaced at
0.1" thus making breadboarding board use impossible, to keep the compatibility we
have the same spacing but we added next to this connector on 0.1" which customer
can use with perforated boards.
