STM32F103RBT6 Maple compatible board, Industrial temp.

Description

Maple is an open-source development environment for ARM Cortex based microcontrollers. Maple boards come in an Arduino-compatible format, complete with Arduino pin layouts and programming environment. The Arduino compatible form-factor allows you to use the various available
Arduino Shields
(add-on boards) with Maple processor boards.
This Maple board uses an STM32F103RBT6 microcontroller (ARM Cortex-M3 core) instead of an 8-bit AVR, thus offering much higher computing speed.
The Olimexino-STM32 takes Maple a step further, addressing issues brought up by Arduino and Maple users, implementing features that have been on Arduino users' wish lists for years:
UEXT Connector
As well as Arduino shield connectors, this board has the Olimex universal extension connector, UEXT, which allows you to add peripheral modules easily. The UEXT can provide I2C, RS232, SPI and power to the external device. Please see the for a full list of modules that can plug into the UEXT port.

9-30V power supply.
The original Arduino/Maple uses a linear power supply; this limits the input voltage range. The Olimexino is designed to accept power from 9 to 30V DC, making it possible to use virtually any power supply adapter on the market. This also enables applications which use a 24V DC industrial power supply. Note: The board works with 3.3V shields only.
Industrial temperature range.
The original design was limited to commercial 0-70C operating temperature. All Olimexino components have been selected to work reliably in the industrial temperature range of -25 to
+85 °C,
so the board can be used in industrial applications.
Ultra low power.
The original Arduino/Maple design is not good for portable applications, as it consumes too much power with its linear voltage regulators. The Olimexino uses ultra-low-power voltage regulators — the consumption is only a few microamps — which enables hand-held and battery-powered applications.
Built-in battery charger.
Olimexino adds a Li-Ion rechargable battery power supply option with an on-board charger, so when you attach a battery it is automatically charged and kept in this state until another power source (USB or external adapter) is removed. Then it automatically will power the board — no jumpers, no switches!
UEXT connector.
This connector allows you to add one of many existing Olimex modules (see below).

RTC.
Olimexino allows for a Real-Time Clock.
Noise immune
design.
Separate voltage regulator for Analog.
This allows the ADC to be read correctly without digital noise pickup.
Provision for Aref precise source.
This is in case you need higher precision and temperature stability in analog reading.
LEDs and buttons on edge of board.
Now they can be seen and touched even when you have shields installed.
All components lower than connectors.
No more interference with your shields.
Mini-USB connector.
Now you can use a cable you may already have for a cell phone or other hand-held device.
0.1" spacing.
The original Arduino design had a flaw: the connectors were not spaced at 0.1" which made perforated board use impossible. While Olimexino includes the same connectors for compatibility with existing shields, it also has 0.1" spaced connectors that you can use with perforated boards.
Top and bottom silkscreen.
All signals on the connectors are printed on the top and the bottom of the board, so when you check with a probe you know exactly which port you are measuring.
