SparkFun MicroMod STM32 Processor

SparkFun MicroMod STM32 Processor

We have ✅ 1 available of the SF-DEV-17713 in our Sydney warehouse.

Express post delivery (2-5 business days)

The SparkFun MicroMod STM32 Processor Board brings the power of the STM32F405 ARM Cortex-M4 microcontroller to the MicroMod ecosystem. Operating at up to 168 MHz with a hardware floating point unit (FPU) and full DSP instruction set, this processor board delivers serious performance in a compact M.2 form factor.

The STM32F405 features 1MB of flash memory, 192KB of SRAM (including 64KB of core-coupled memory), and the board adds an additional 128Mb (16MB) of serial flash. Code is uploaded via the DFU bootloader. Simply align the keyed M.2 connector with any MicroMod Carrier Board and secure with the included screw.

Key Features

  • ARM Cortex-M4 Core – 32-bit RISC with FPU, DSP instructions, and memory protection unit
  • Up to 168 MHz – 210 DMIPS / 1.25 DMIPS/MHz (Dhrystone 2.1)
  • 1MB Flash + 192KB SRAM – Plus 16MB additional serial flash onboard
  • DFU Bootloader – Upload code via USB without a separate programmer
  • M.2 MicroMod Connector – Swap processors on any MicroMod Carrier Board
  • Low Power Modes – Sleep, Stop, and Standby for battery-powered applications
  • 1.8–3.6V I/O – Flexible voltage range
