STM32 starter kit NUCLEO-H503RB STM32H503RBT6 ARM CORTEX-M33 NUCLEO-64

The NUCLEO-H503RB is an evaluation kit from ST Microelectronics, featuring the STM32H503RBT6 microcontroller. This microcontroller is based on 32-bit ARM Cortex-M4 core, which reaches a maximum clocking of up to 170 MHz. It contains 512 kB of Flash memory and 112 kB of SRAM, as well as built-in accelerators for mathematical and arithmetic functions to enhance computing performance. The STM32 Nucleo-64 series, to which this kit belongs, offers chips in 64-pin enclosures. The kit has two expansion connectors: one compatible with Arduino Uno R3 and the other ST Morpho, allowing modules and extensions to be added easily. Kit specification:

* Microcontroller: STM32H503RBT6 in an LQFP64 enclosure, providing advanced computing capabilities.

* Control and signalling elements:

* 1 x User LED: For visual indication of programme operation.

* Buttons: 1 x user button and 1 x RESET button to interact with the device.

* Quartz generator:

* LSE: With a frequency of 32.768 kHz, for precise timekeeping.

* Connectors on the board:

* ST Zio: Includes a connector compatible with ARDUINO® Uno V3.

* ST Morpho: Allows easy expansion of the kit's functionality.

* Power options:

* Flexible power sources: via USB VBUS from ST-LINK, directly from the USB connector, or from an external power supply (3.3 V, 5 V, 7-12 V).

* Programmer/Debugger:

* STLINK-V3EC: Integrated programmer/debugger with SWD interface that can also work with external circuits, increasing the diagnostic and programming capabilities of the kit.

The NUCLEO-H503RB kit is ideal for designers and developers who need the flexibility to expand their systems and work efficiently with advanced STM32 microcontrollers.
