A few days ago, we looked at the WeAct Studio STM32U585CIU6 development board, which features an ultra-low-power STM32U5 Cortex-M33 MCU and was added to MicroPython v1.28. If you’re looking for another STM32U5-based option, especially for compact UI projects, Maker Go now offers an STM32U575 board with a display connector, a microSD card slot, and many more GPIOs
While the STM32U585 on the WeAct board features cryptographic accelerators, the STM32U575VGT6 MCU on the Maker Go board is closely related and still offers the same high-performance Cortex-M33 core running at 160 MHz, along with ultra-low-power capabilities. This new board also adds 8MB of external flash and is designed to accept 1.47-inch or 2.0-inch LCDs directly via a ribbon cable.
STM32U575VGT6 board specifications:
- Microcontroller – ST STM32U575VGT6
- Core – Arm Cortex-M33 Armv8-M core clocked at up to 160 MHz with FPU, Arm TrustZone
- Memory – 786 KB SRAM
- Flash – 1024 KB (1 MB) flash
- GPU – Chrom-ART accelerator (DMA2D) for 2D graphics
- Package – LQFP100 (14 x 14 mm)
- Storage
- 8MB SPI Flash (WSON8 package)
- MicroSD card slot
- Display – FPC expansion interface compatible with 1.47-inch (320×172) and 2.00-inch (320×240) displays
- USB – USB Type-C port for power and programming (supports USB download)
- Expansion – 2x 48-pin headers exposing GPIOs, 3.3V, 5V, and GND
- Debugging/Programming:
- Dedicated SWD download interface (3v3, RST, RX, TX, 5V, GND, DIO, CLK)
- Supports Downloader, USB, and Serial port burning methods
- Misc
- Reset and User/Boot (two-in-one) buttons
- Power LED and RGB LED
- High-speed crystal oscillator
- RTC
- Power Supply – 5V via USB Type-C; 1A high-current DC-DC power supply with ESD protection
- Dimensions – 59.7 mm x 35.8 mm (2350.0mil x 1410.0mil)
The board uses a breadboard-friendly layout, though you will need to solder the provided header pins yourself. The manufacturer mentions that the three primary ways to flash the board are via a standard SWD downloader (like an ST-Link), directly over USB, or via the serial port.
On the software side, there aren’t any specific resources for this board, but STMicroelectronics provides the STM32Cube IDE and HAL libraries for C/C++ development. While there is no official MicroPython firmware release specifically for this board, the MicroPython v1.27 update added core support for the STM32U5 series, which means you should technically have support for the MCU. You can also check out the official STM32CubeU5 GitHub repository for more information.
The STM32U575 development board is available on AliExpress for $15.00, but there aren’t any options to purchase it bundled with a display. While Maker Go mentions “QSZNTEC” and “IO Impulse”, I couldn’t find any information about either, although we suspect the former is a brand and the latter might be the nickname of the hardware designer. Besides Maker Go, the board can also be found on other AliExpress stores at different price points.
