Microcontroller sourcing guide: STM32F1, STM32F4, STM32F7, STM32H7 series. ADD Components stocks STMicroelectronics MCUs in depth — from entry-level to high-performance ARM Cortex-M — with full traceability and anti-counterfeit verification.
Microcontrollers (MCUs) — The Brains of Embedded Systems
A microcontroller integrates a processor core, memory, and programmable I/O peripherals on a single chip. From washing machines to industrial robots to FPV drones, MCUs execute real-time control code in billions of deployed devices.
ADD Components specializes in STMicroelectronics (STM) microcontrollers — the industry's most widely adopted ARM Cortex-M portfolio. We stock STM32F1, STM32F4, STM32F7, and STM32H7 series in depth, serving OEMs across Eastern Europe and Central Asia.
MCU Classification
8-Bit MCUs
Simple, low-cost controllers for basic tasks — appliance timers, LED drivers, sensor polling. Low power consumption, easy to program, still in mass production.
16-Bit MCUs
Mid-range controllers offering more processing power and memory than 8-bit, with better power efficiency than 32-bit in certain niches. Used in automotive body electronics and motor control.
32-Bit ARM Cortex-M MCUs
The dominant embedded processing architecture today. From Cortex-M0 (ultra-low-power) to Cortex-M7 (DSP + FPU, 600+ DMIPS), the STM32 family spans the full performance and power spectrum. This is where the majority of new embedded designs live.

FPV and UAV Focus — STM32 in Flight Controllers
STM32 MCUs power the vast majority of FPV flight controllers — from 3-inch micro quads to industrial inspection drones. The F405 is the current Betaflight gold standard. The F722 and H7 are the go-to for high-loop-time PID controllers, GPS navigation, and autonomous flight stacks. ADD carries deep inventory across all STM32 variants used in flight controller design, including companion sensors (IMU, barometer, OSD) and MOSFET gate drivers for ESCs.
