STMicroelectronics (STM32) Design Services
STMicroelectronics' STM32 is the broadest Arm Cortex-M microcontroller family, scaling from ultra-low-power (STM32L/U) to high-performance (STM32H) and wireless (STM32WB/WL) parts that share one toolchain.
STM32 is the safe, scalable default for general embedded designs. Because the whole range shares peripherals and the STM32Cube ecosystem, you can move up or down in performance, memory and cost without re-architecting — valuable when requirements shift or parts go short.
Key product families
STM32L / STM32U
Ultra-low-power lines for battery and energy-harvesting designs.
STM32F / STM32G
Mainstream Cortex-M0+/M4 parts balancing cost and capability.
STM32H
High-performance Cortex-M7 for DSP, graphics and demanding control.
STM32WB / STM32WL
Integrated BLE/802.15.4 (WB) and sub-GHz LoRa (WL) wireless MCUs.
When to choose it
- You want one scalable family across a product line
- Motor control, mixed-signal, or deterministic real-time control
- Long-term availability and a large support ecosystem matter
Typical applications
How Rapid Circuitry designs with STMicroelectronics
Rapid Circuitry designs custom STM32 boards across the range, builds firmware on STM32Cube/HAL or bare-metal, and handles the mixed-signal and motor-control layout that these parts are chosen for.
Frequently asked questions
STM32 vs ESP32 — which should I pick?
Pick STM32 when you need a scalable MCU family, deterministic control, rich analog/motor peripherals, or long-term supply. Pick ESP32 when integrated Wi-Fi/Bluetooth at low cost is the priority. Many products use both — an STM32 for control and an ESP32 for connectivity.
Does STM32 support wireless?
Yes. The STM32WB integrates Bluetooth LE and 802.15.4 (Thread/Zigbee), and the STM32WL integrates a sub-GHz LoRa radio, while other STM32 parts pair with external radios.
