Olimex OLIMEXINO-STM32 Development Board
Olimex OLIMEXINO-STM32 Development Board is based on the Arduino open-source electronics prototyping platform and the Maple project. It is designed around the ARM7 STM32F103RBT6 microcontroller, a high-performance ARM Cortex™-M3 32-bit RISC core operating at a 72MHz frequency, with high-speed embedded memory, and an extensive range of enhanced I/Os and peripherals connected to two APB buses. The OLIMEXINO-STM32 Board uses a DC/DC power supply which accepts power from 9 to 30V DC, making it possible to use virtually any power supply adapter on the market and also enabling applications which operate on an industrial power supply of 24VDC. This board uses ultra low power voltage regulators with a consumption of only a few microamps, which enables handheld and battery-powered applications. Olimex OLIMEXINO-STM32 Development Board also features a Li-Ion rechargeable battery power supply option, UEXT connector, SD-MMC card support, CAN driver, RTC, noise immunity, mini USB connector, and a separate voltage regulator for the analog part, which allows the ADC to be read correctly without digital noise pickup. This board has four mount holes to make attachment easier and is reliable in industrial temperatures ranging from -25ºC to +85ºC.
