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.
