Nucleo U575ZI-Q and X-Nucleo GFX02ZI
The perfect combination for developing IoT applications on the STM Arm M33 Ultra-Low-Power platform.
Pros
- TouchGFX Designer support
- Very intuitive and easy to use
- Powerful Ultra-low-power MCU
Cons
- Low screen resolution
- The demo application does not work out-of-the-box
The STM32 Nucleo U575ZI-Q is a Nucleo-144 development boards with an STM32U575ZIT6Q MCU on-board and connectors for Arduino, ST Zio and morpho accessories. The MCU features an ultra-low-power Arm Cortex-M33 core with a built-in FPU unit, running at 160 MHz. The MCU also packs 2 MB of Flash memory. Additionally, the board features a programmable USB port for interfacing through code.
For a little test, we paired the X-Nucleo GFX02ZI full-color 320×240 LCD screen with the dev board. As of the time of writing, this development board is the only Nucleo-144 model which features full support of such add-on screens using the TouchGFX Designer suite – available from STM’s own website.
TouchGFX designer is pleasant to use and is capable of easily generating starter code for graphical user interfaces, which can then be edited further in the standard Cube IDE.
Unfortunately, the X-Nucleo GFX02ZI display doesn’t have the highest resolution – if it were any lower, many applications would be unsuitable for such a low number of pixels. Still, it’s the best currently supported Nucleo screen. If you want to create a device using an ultra-low-power but high-performance ARM MCU, the Nucleo U575ZI-Q is an excellent starter kit – with its wide range of IOs and the aforementioned USB port which can support various external devices, like keyboards or other UART devices. The board can truly provide days and days of development opportunities just on its own – and we definitely recommend it.
