Figure 3-1 Nucleo F7 board and LoRa GW module 

3.1 Nucleo-F746ZG Board 

Information about the STM32 Nucleo board is available on 

www.st.com

 . 

The NUCLEO-F746ZG board embeds an STM32F746ZG MCU, ARM® 32-bit Cortex®-M7 CPU with 

FPU, adaptive real-time accelerator (ART Accelerator™) and L1-cache: 4KB data cache and 4KB 

instruction cache, allowing 0-wait state execution from embedded Flash memory and external 

memories, frequency up to 216 MHz, MPU, 462 DMIPS/2.14 DMIPS/MHz (Dhrystone 2.1), and DSP 

instructions.
