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 sup-
ply 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 Com-
mercial 0 – 70C operating temperature.
3.
The original Arduino/MAPLE design is not very reliable for portable applications as con-
sumes it too much power with the linear voltage regulators, we put ULTRA LOW POWER voltage
regulators and the consumption is only few microampers, which enables handheld and battery pow-
ered 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 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.
Our board has micro SD 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 cor-
rectly without the digital noise pickup.
11.
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.
12.
All components are LOWER than the connectors, so the shields do not interfere with them.
13.
mini USB connector is used which is common and used in most cell phones, so you do not
have to buy other cables
14.
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.
15.
All signals on the connectors are printed on top and on bottom of the board, so when you
check with probe you know exactly which port you are measuring.
16.
4 mount holes make board attachment easier
