The hardware consists of a simple open hardware design for the Arduino board with an Atmel AVR processor and on-board I/O support. The software consists of a standard programming language and the boot loader that runs on the board. Arduino hardware is programmed using a Wiring-based language (syntax + libraries), similar to C++ with some simplifications and modifications, and a Processing-based Integrated Development Environment (IDE). The project began in Ivrea, Italy in 2005 aiming to make a device for controlling student-built interaction design projects less expensively than other prototyping systems available at the time. As of February 2010 more than 120,000 Arduino boards had been shipped. Founders Massimo Banzi and David Cuartielles named the project after a local bar named “Arduino”. The name is an Italian masculine first name, meaning "strong friend". The English pronunciation is "Hardwin", a namesake of Arduino of Ivrea. More information could be found at the creators web page http://arduino.cc/ and in the Arduino Wiki http://en.wikipedia.org/wiki/Arduino To make the story short – Arduino is easy for beginners who lack Electronics knowledge, but also does not restrict professionals as they can program it in C++ or mix of Arduino/C++ language. There are thousands of projects which makes it easy to startup as there is barely no field where Arduino enthusiasts to have not been already. Arduino has inspired two other major derivatives – MAPLE and PINGUINO. Based on 8-bit AVR technology the computational power of Arduino boards is modest, this is why a team from MIT developed the MAPLE project which is based on ARM7 STM32F103RBT6 microcontroller. The board has same friendly IDE as Arduino and offers the same capabilities as hardware and software but runs the Arduino code much faster. Unfortunately, by year 2016, the MAPLE project is now no longer supported and updated. The remaining resources of the Maple project can be found at http://leaflabs.com In parallel with Arduino another project was started called PINGUINO. This project chose its first implementation to be with PIC microcontrollers, as AVRs were hard to find in some parts of the world like South America so it is likely to see lot of PINGUINO developers are from that part of the world. PINGUINO project founders decided to go with Python instead Java for processing language. For the moment PINGUINO is much more flexible than Arduino as it is not limited to 8bit microcontrollers. Currently the IDE, which has GCC in background, can support 8-bit PIC microcontrollers, 32bit PIC32 (MIPS) microcontrollers and ARM7/CORTEXM3 microcontrollers which makes PINGUINO very flexible because once you make your project you can migrate easily through different hardware platforms and not being bound to a single microcontroller manufacturer. The PINGUINO project can be found at: http://www.pinguino.cc.

We had the possibility to read current customer feedback and to implement what they wanted to see in the original Arduino. 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. 1. 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. 2. The original Arduino/MAPLE design is not very reliable for portable applications as consumes 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 powered applications. 3. 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! 4. Our board has UEXT connector which allows many existing modules like RF, ZIGBEE, GSM, GPS to be connected. 5. 6. 7. 8. 9. 10. Our board has micro SD card Our board has CAN driver on board Our design allows RTC – Real Time Clock. We made our design noise immune. We use separate voltage regulator for the Analog part, which allows the ADC to be read correctly without the digital noise pickup. 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. 11. 12. 13. All components are LOWER than the connectors, so the shields do not interfere with them. mini USB connector is used which is common and used in most cell phones, so you do not have to buy other cables 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. 14. 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. 15. 16. 4 mount holes make board attachment easier Page 3 of 19 ELECTROSTATIC WARNING: The OLIMEXINO-STM32 board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board. BOARD USE REQUIREMENTS: HARDWARE REQUIREMENTS: - Cables: You'll need a USB cable with mini USB connector for connecting the board to a personal computer and MAPLE IDE. The board also gets powered via this cable. - ARM programing tool (optional but recommended): STM32-compatible programmer/debugger is recommended: 1. if you wish to use a general-purpose approach of programming (not bootloader and USB method) 2. if you wish to change the bootloader with MPIDE bootloader 3. if you managed to overwrite the bootloader program and wish to recover the device You can use any STM32F103 compatible programmer or debugger just notice that the board has a 10-pin mini JTAG/SWD connector (0.05” step) – make sure that you have a suitable adapter. You can use ARMJTAG-20-10 adapter for this task. Our ARM-USB-OCD-H, ARM-USB-TINY-H, ARM-JTAG-COOCOX tools are capable of programming the board (remember the adapter). SOFTWARE REQUIREMENTS: - Environment (recommended) By default the board comes with MAPLE IDE bootloader. It is recommended to use MAPLE IDE initially. - Environment (recommended) Since the MAPLE project is now completely abandoned it is recommended to either use an alternative (MPIDE; Espruino IDE; stm32duino; etc) or use general-purpose method of programming. It is important to notice that the STM32 chip has internal bootloader which can be used to change any code without JTAG debugger. Please find instructions on how to use “STM32 Flash Load Demonstrator” in the wiki article: https://www.olimex.com/wiki/How_to_use_OLIMEXINO-STM32_with_Espruino_IDE Note that usually the general-purpose require a programmer or debugger in order to interact with the board.

RESET CIRCUIT: OLIMEXINO-STM32 reset circuit includes D6 (1N4148), R28 (10kΩ), R29 (330Ω), C31 (100nF), STM32F103RBT6 pin 7 (NRST) and RESET button. CLOCK CIRCUIT: Quartz crystal Q1 8 MHz is connected to STM32F103RBT6 pin 5 (PD0/OSC_IN) and pin 6 (PD1/OSC_OUT). Quartz crystal Q2 32.768 kHz is connected to STM32F103RBT6 pin 3 (PC14/OSC32_IN) and pin 4 (PC15/OSC32_OUT). JUMPER DESCRIPTION: Note that all jumpers on the board are SMD type. You will need to solder/unsoder/cut them in order to reconfigure them. LED1_E This jumper, when is closed, enables LED1. Default state is closed. LED2_E This jumper, when is closed, enables LED2. Default state is closed. D23_E This jumper, when is closed, connects STM32F103RBT6 pin (PC15/OSC32_OUT) – signal D23 to EXT pin 1, and when is opened, D23 is not connected to EXT. Default state is opened. R-T This jumper, when is closed, connects TRST and RESET, and when is opened, TRST and RESET are separated. Default state is opened. Page 7 of 19 CAN_T This jumper, when is closed, CAN termination is enabled, and when is opened, CAN termination is disabled. Default state is opened. D10/D4 This jumper, when is in position D10, UEXT pin 10 (UEXT_#CS) is connected to STM32F103RBT6 pin 20 (PA4/SPI1_NSS/USART2_CK/ADC4) – signal D10, and when is in position D4, UEXT pin 10 (UEXT_#CS) is connected to STM32F103RBT6 pin 57 (PB5/I2C1_SMBAI/TIM3_CH2/SPI1_MOSI) – signal D4. Note that P10_E's effect also is affected by D10/D4. Default state is in position D4. P10_E: When closed the board provides 3.3V to the UEXT_CCS – UEXT pin. Default state is closed. 3V3A/5V This is a new jumper introduced in hardware revision F of the board. It changes the voltage provided to pin #3 of the power shield connector from the default 5V to 3.3VA. IMPORTANT! Hardware revision F introduced changes to the POWER connector of the Arduino shield. Now there are 5V available at pin #3 of the POWER connector by default! It was 3.3V in older revisions. Be careful if you use 3.3V shields! You can revert the voltage of the pin back to 3.3V if you change the position of the 3V3A/5V jumper! Default state is in position 5V. INPUT/OUTPUT: Status Led with name LED1 (green) connected via jumper LED1_E to STM32F103RBT6 pin 21 (PA5/SPI1_SCK/ADC5) – signal D13(SCK/LED1). Status Led with name LED2 (yellow) connected to STM32F103RBT6 pin 15 (PA1/USART2_RTS/ADC1/TIM2_CH2) – signal D3(LED2). Power-on LED (red) with name PWR_LED – this LED shows that the board is power supplied. User button with name BUT connected to STM32F103RBT6 pin 40 (PC9/TIM3_CH4) via R33 (1kΩ) and pin 60 (BOOT0) – signal BOOT0. User button with name RST connected to STM32F103RBT6 pin 7 (NRST).

This is normal, we also do development work and we have damaged A LOT of programmers and boards during our daily job so we know how it works. If our board/programmer has worked fine then stopped, please check if you didn't apply over voltage by mistake, or shorted something in your target board where the programmer was connected etc. Sometimes boards might get damaged by ESD shock voltage or if you spill coffee on them during your work when they are powered. Please note that warranty do not cover problems caused by improper use, shorts, over-voltages, ESD shock etc. If the board has warranty label it should be not broken. Broken labels void the warranty, same applies for boards modified by the customer, for instance soldering additional components or removing components – such boards will be not be a subject of our warranty. If you are positive that the problem is due to manufacturing defect or component you can return the board back to us for inspection. When we receive the board we will check and if the problem is caused due to our fault and we will repair/replace the faulty hardware free of charge, otherwise we can quote price of the repair. Note that all shipping back and forth have to be covered by the customer. Before you ship anything back you need to ask for RMA. When you ship back please attach to it your shipping address, phone, e-mail, RMA# and brief description of the problem. All boards should be sent back in antistatic package and well packed to prevent damages during the transport. Page 19 of 19
