Provides 3.3V as output can also be used to power the MCU Each category pin can be tabulated as follows: The Arduino pins are split into category CN5, CN6, CN8, and CN9. The arduino like pins are female connector pins which exactly match the order and position of Arduino UNO pins and hence any Arduino shield can be used with these development boards. The pin one resembles the Arduino UNO and the blue one is the STM32 style ( Morpho). As you can see, there are two sets of pins. The STM32 Nucleo board pinout is shown above. The Board operates with 3.3V supply but a wide voltage range of 7-12V can be provided to the VIN pin since it has an on-board voltage regulator. Similarly, there are two push buttons where one is user programmable, and the other is to reset the Microcontroller. This board also comes with an integrated ST-LINK/V2-1 programmer and debugger hence it is very easy to get started with this board.Īs shown in the image above, there are three LEDs, where LD1 is for indicating USB communication, LD2 is programmable LED, and LD3 indicates power. The Boards pinout is similar to Arduino UNO and has many other additional pins to expand performance. It features the ARM Cortex M4 32-bit STM32F401RET6 microcontroller which is in LQFP64 package. One 12-bit, 1.The STM32 Nucleo boards are the official Development Boards from STMicroelectronics.Up to 69 I/Os with 5V-tolerant capability and 19 with independent supply V DDIO2.All mappable on external interrupt vectors.Internal 48 MHz oscillator with automatic trimming based on ext.32 kHz oscillator for RTC with calibration.V BATsupply for RTC and backup registers.Digital & I/Os supply: V DD= 2.0 V to 3.6 V.Core: ARM ®32-bit Cortex ®-M0 CPU, frequency up to 48 MHz.These features make the STM32F091xB/xC microcontrollers suitable for a wide range of applications such as application control and user interfaces, hand-held equipment, A/V receivers and digital TV, PC peripherals, gaming and GPS platforms, industrial applications, PLCs, inverters, printers, scanners, alarm systems, video intercoms and HVACs. Depending on the device chosen, different sets of peripherals are included. The STM32F091xB/xC microcontrollers include devices in seven different packages ranging from 48 pins to 100 pins with a die form also available upon request. A comprehensive set of power-saving modes allows the design of low-power applications. The STM32F091xB/xC microcontrollers operate in the -40 to +85 ☌ and -40 to +105 ☌ temperature ranges, from a 2.0 to 3.6 V power supply. The device offers standard communication interfaces (two I 2Cs, two SPIs/one I 2S, one HDMI CEC and up to eight USARTs), one CAN, one 12-bit ADC, one 12-bit DAC with two channels, seven 16-bit timers, one 32-bit timer and an advanced-control PWM timer. The STM32F091xB/xC microcontrollers incorporate the high-performance ARM ®Cortex ®-M0 32-bit RISC core operating at up to 48 MHz frequency, high-speed embedded memories (up to 256 Kbytes of Flash memory and 32 Kbytes of SRAM), and an extensive range of enhanced peripherals and I/Os.
