Olimex OLIMEXINO-STM32 Board with STM32F103RBT6 Microcontroller

The Olimex OLIMEXINO-STM32 serves as a versatile development board, drawing inspiration from Arduino and Maple designs while leveraging the power of the STM32F103RBT6 microcontroller. Engineered for reliability in challenging environments, this board features a DCDC power supply capable of accepting input voltages from 9 to 30V DC, making it compatible with a wide range of industrial power sources (24VDC) and ensuring operation across an industrial temperature range of -25 to +85°C. Its robust design focuses on noise immunity, enhanced by a separate voltage regulator for the analog section to guarantee accurate ADC readings.

Beyond its industrial capabilities, the OLIMEXINO-STM32 prioritizes ultra-low power consumption, making it ideal for handheld and battery-powered applications. It includes an onboard Li-Ion rechargeable battery charger, which intelligently manages power, automatically switching to battery power when external sources are removed without requiring manual intervention. This seamless power management, combined with convenient edge-mounted LEDs and buttons, simplifies development and deployment.

Addressing a common limitation in older Arduino designs, the board provides both traditional and precisely spaced 0.1″ pitch connectors, ensuring maximum compatibility with shields and prototyping setups. All signal names are clearly printed on both sides of the PCB, facilitating easy debugging and connection verification, while four mounting holes ensure secure integration into projects.
