STM32-H405 is a general-purpose development board that allows the evaluation of STM32F405.

The STM32F405RG ARM Cortex-M4 processor is part of the latest generation of ARM processors for embedded systems. It has been developed to provide a low-cost platform that meets the needs of a MCU with reduced pin count and low-power consumption, while delivering high computational performance and an advanced system response to interrupts. The ARM Cortex-M4 32-bit RISC processor features exceptional code-efficiency, delivering the high-performance expected from an ARM core in the memory size usually associated with 8- and 16-bit devices.

STM32-H405 is a minimal start-up board for evaluating the new ST Cortex-M4 microcontrollers. The board has a standard 20-pin JTAG/SWD connector. The board features two headers with all microcontroller signals near it, giving the customer an easy way to implement his own schematics and add-ons. The STM32-H405 board is compatible with all the tools and software used in typical ARM development environment.

New version with GD32F405RGT6 pin to pin compatible MCU is available. Notice that software and bianries made for STM32-H405 might not work without re-building with GD32-H405. Your software should support GD32F405 and you should rebuild your project with GD32F405 set as target.
