STMicroelectronics NUCLEO-H723ZG STM32 Nucleo-144 Board is designed to provide an affordable and flexible way to try out new concepts and build prototypes. This is made possible by choosing the various combinations of performance and power consumption features that are provided by the STM32 microcontroller. This board features the STM32 microcontroller in an LQFP144 package, three user LEDs, two user and reset push-buttons, and a 32.768kHz crystal oscillator. The NUCLEO-H723ZG board offers a Serial Wire Debug (SWD) connector, an ST Zio expansion connector including ARDUINO® Uno V3, and the ST morpho expansion connector. This board has an onboard ST-LINK debugger/programmer with USB re-enumeration capability for mass storage, virtual COM port, and debug port. The NUCLEO-H723ZG board is Ethernet compliant with IEEE-802.3-2002 and Arm® Mbed Enabled™ compliant.
