STM32 vs ESP32 Architectures

Depending on your operational environment, we configure custom boards with either deterministic real-time STM chips or cloud-native ESP engines.

STM32 (ARM Cortex) Platforms

Deterministic Control

Best suited for heavy machinery automation, solar telemetry sub-meters, and high-frequency analog sensor analysis.

  • Dual-core ARM Cortex-M4/M7 running up to 480 MHz
  • Hardware-in-the-loop DSP instructions for vibration FFT
  • Galvanic isolated communication interfaces (CAN, RS485)
Power: 3.3V DC STM32CubeMX / RTOS

ESP32 (Tensilica Xtensa) Platforms

Cloud-Native Connectivity

Best suited for battery-powered remote fields (agriculture soil suites), smart relays, and wireless mesh networks.

  • Tensilica 32-bit LX6/LX7 dual-core chips
  • Integrated Wi-Fi & Bluetooth LE antennas
  • Deep sleep modes drawing less than 5µA current
Power: 3.3V / LiPo Battery ESP-IDF / FreeRTOS
