Technical Review: STM32H723ZGT6 Development Board - Selection Guide & Specs
Share
The STM32H723ZGT6 sits at the high end of ST's Cortex-M7 lineup, and the development board built around it — often sold as an STM32H723 core board or learning board — is the fastest way to put that performance on your bench. This page summarizes what the chip actually offers and what to check before you buy a board.

What a "development board" adds
The chip alone is an LQFP144 surface-mount part — not breadboard-friendly. A development board breaks out the pins to headers, adds the crystal, reset/boot circuitry, USB connector and usually an SWD header, so you can flash and debug immediately with ST-Link. Typical uses: evaluating the H723 for a product, learning Cortex-M7 peripherals, driving displays via Chrom-ART, or prototyping motor control with the high-resolution timers.
Choosing between H723 and other STM32 lines
- vs STM32F4 (168–180 MHz): the H723 roughly triples CPU performance and doubles ADC speed. Choose F4 when cost matters and the application fits; choose H723 for DSP-heavy work.
- vs STM32H743/H750: the H743 offers more RAM options and a second core variant family; the H723 is the newer value-oriented 550 MHz line. For most learning and evaluation purposes they are interchangeable in tooling.
- vs STM32H723 vs F103 boards: if you are just starting with STM32, an F103 "Blue Pill"-class board is cheaper; move to the H723 when you need the M7's DSP and graphics capability.
What to check on the board before buying
- Debugger: onboard ST-Link or an external SWD header — without one you cannot flash easily.
- Power input: 5 V via USB with an onboard 3.3 V regulator is the norm; confirm the regulator can supply your peripherals.
- Pin labels: a board with silkscreen pin names saves hours against the 144-pin datasheet.
- Boot configuration: BOOT0 jumper or button for serial/DFU boot.
Frequently asked questions
Is STM32H723ZGT6 good for beginners?
It works, but it is a high-end chip. If you are new to embedded, an F103 or F4 board is a gentler start. Choose the H723 board when you specifically need 550 MHz performance, DSP instructions, or the graphics accelerator.
What toolchain does the STM32H723 use?
Standard ST tooling: STM32CubeIDE, STM32CubeMX for configuration, and ST-Link for flashing/debugging. Third-party toolchains (Keil, IAR, PlatformIO, VS Code + Cortex-Debug) also support the H723.
Does the board come with the chip soldered?
Yes — the development board ships with the STM32H723ZGT6 soldered. Check the listing condition notes; every order carries a 1-year warranty.
Can I use Arduino libraries on the STM32H723?
Largely yes via the STM32duino core, with the usual caveat that H7-specific peripherals (Chrom-ART, JPEG codec, hardware JPEG, TCM layout) need HAL-level code rather than Arduino wrappers.
