ARM® Cortex®-M4 microcontrollers
Geehy Semiconductor continuously expands its portfolio of 32-bit microcontrollers from the APM32F series, which can successfully replace the currently hard-to-obtain STM32F microcontrollers.
With the beginning of 2022, microcontrollers from the APM32F407 series were introduced, which are equivalents of ST products from the "Foundation line" family of STM32F407.

Technical support
As an authorized distributor of Geehy Semiconductor, Micros offers technical support for migrating from STM32F MCU or any other ARM-based MCU to the APM32F alternative. In many applications APM32F MCUs are drop-in replacements for STM32F MCUs and no changes in the software are necessary. But in some applications some minor changes might be needed.
Geehy Semiconductor has built strong and well-experienced engineering team that is willing to help for any isssues related to the software.
